Deiner MS, Lietman TM, McLeod SD, Chodosh J, Porco TC. Surveillance Tools Emerging From Search Engines and Social Media Data for Determining Eye Disease Patterns. JAMA Ophthalmol 2016;134(9):1024-30.Abstract

IMPORTANCE: Internet-based search engine and social media data may provide a novel complementary source for better understanding the epidemiologic factors of infectious eye diseases, which could better inform eye health care and disease prevention. OBJECTIVE: To assess whether data from internet-based social media and search engines are associated with objective clinic-based diagnoses of conjunctivitis. DESIGN, SETTING, AND PARTICIPANTS: Data from encounters of 4143 patients diagnosed with conjunctivitis from June 3, 2012, to April 26, 2014, at the University of California San Francisco (UCSF) Medical Center, were analyzed using Spearman rank correlation of each weekly observation to compare demographics and seasonality of nonallergic conjunctivitis with allergic conjunctivitis. Data for patient encounters with diagnoses for glaucoma and influenza were also obtained for the same period and compared with conjunctivitis. Temporal patterns of Twitter and Google web search data, geolocated to the United States and associated with these clinical diagnoses, were compared with the clinical encounters. The a priori hypothesis was that weekly internet-based searches and social media posts about conjunctivitis may reflect the true weekly clinical occurrence of conjunctivitis. MAIN OUTCOMES AND MEASURES: Weekly total clinical diagnoses at UCSF of nonallergic conjunctivitis, allergic conjunctivitis, glaucoma, and influenza were compared using Spearman rank correlation with equivalent weekly data on Tweets related to disease or disease-related keyword searches obtained from Google Trends. RESULTS: Seasonality of clinical diagnoses of nonallergic conjunctivitis among the 4143 patients (2364 females [57.1%] and 1776 males [42.9%]) with 5816 conjunctivitis encounters at UCSF correlated strongly with results of Google searches in the United States for the term pink eye (ρ, 0.68 [95% CI, 0.52 to 0.78]; P < .001) and correlated moderately with Twitter results about pink eye (ρ, 0.38 [95% CI, 0.16 to 0.56]; P < .001) and with clinical diagnosis of influenza (ρ, 0.33 [95% CI, 0.12 to 0.49]; P < .001), but did not significantly correlate with seasonality of clinical diagnoses of allergic conjunctivitis diagnosis at UCSF (ρ, 0.21 [95% CI, -0.02 to 0.42]; P = .06) or with results of Google searches in the United States for the term eye allergy (ρ, 0.13 [95% CI, -0.06 to 0.32]; P = .19). Seasonality of clinical diagnoses of allergic conjunctivitis at UCSF correlated strongly with results of Google searches in the United States for the term eye allergy (ρ, 0.44 [95% CI, 0.24 to 0.60]; P < .001) and eye drops (ρ, 0.47 [95% CI, 0.27 to 0.62]; P < .001). CONCLUSIONS AND RELEVANCE: Internet-based search engine and social media data may reflect the occurrence of clinically diagnosed conjunctivitis, suggesting that these data sources can be leveraged to better understand the epidemiologic factors of conjunctivitis.

DeLoss KS, Le H-G, Gire A, Chiu GB, Jacobs DS, Carrasquillo KG. PROSE Treatment for Ocular Chronic Graft-Versus-Host Disease as a Clinical Network Expands. Eye Contact Lens 2016;42(4):262-6.Abstract

BACKGROUND: Keratoconjunctivitis sicca occurs in 40% to 90% of patients with ocular chronic graft-versus-host disease (cGVHD). Ocular symptoms can have profound effects in both the visual function and quality of life of patients with GVHD. We report the impact of prosthetic replacement of the ocular surface ecosystem (PROSE) treatment in patients with cGVHD as a clinical network expands. METHODS: We queried the BostonSight PROSE manufacturing database from January 2002 to December 2011. Patients treated for ocular cGVHD were reported by age, gender, year, and network site where the treatment was undertaken. The baseline and six-month follow-up scores of visual function using a standardized validated instrument, the National Eye Institute Visual Function Questionnaire (NEI VFQ-25), were evaluated for a period in 2006 and again in 2010 after network expansion had occurred. RESULTS: A total of 407 patients with a male:female ratio of 226:181, mean age was 51 years with ocular cGVHD underwent PROSE treatment from January 2002 to December 2011. By 2011, 67% of all cases were treated at network clinics. Baseline characteristics of patients treated throughout the network in 2010 were similar to that of 2006 and 2010 cohorts from the main center. There was a significant improvement of 41 points (P<0.001) in composite NEI VFQ score among patients treated across the network in 2010, similar to the improvement of 30 points (P<0.001) seen among the patients treated at the main center in 2010. There was a trend toward lower baseline self-reported general health status (SRGHS) and VFQ scores among patients treated at network clinics, suggesting that expansion of the network allows treatment of sicker patients (lower general health status) or those more severely affected by ocular cGVHD. CONCLUSIONS: PROSE treatment of ocular cGVHD has increased in the last decade with the establishment of BostonSight network clinics across the United States. Patients treated at network clinics showed similar levels of baseline visual function and SRGHS, and achieved a similar high level of improvement in visual function as those treated at the main center. Patient-reported measures of functional status are useful in evaluating treatment options for patients with cGVHD. PROSE treatment has significant positive impact on the visual function of patients with ocular cGVHD regardless of whether the patient is treated at the main center or at a network site.

Di Zazzo A, Tahvildari M, Florakis GJ, Dana R. Ocular Manifestations of Inherited Phospholipase-Cγ2-Associated Antibody Deficiency and Immune Dysregulation. Cornea 2016;Abstract

PURPOSE: To report the ocular manifestations of phospholipase-Cγ2-associated antibody deficiency and immune dysregulation (PLAID). METHODS: Case report and literature review. RESULTS: A 21-year-old woman diagnosed with PLAID was referred for evaluation of repeated episodes of ocular inflammation resulting in bilateral peripheral corneal pannus with episcleritis and corneal scarring accompanied by systemic manifestations including epidermolysis bullosa and interstitial lung disease. Systemic immunosuppression with corticosteroids and interleukin-1 (IL-1) receptor antagonist (anakinra) was supplemented with topical anakinra to avoid systemic side effects, which resulted in partial improvement of the ocular symptoms. Oral prednisone was restarted to treat active lesions during bouts of inflammation. CONCLUSIONS: Ocular PLAID is a bilateral chronic or recurrent inflammatory disease of the ocular surface leading to severe and early cicatricial ocular surface and corneal involvement because of high IL-1 production. Management of PLAID may require both topical and systemic immunomodulatory treatments, potentially including targeted local anti-IL-1 therapy.

Di Zazzo A, Kheirkhah A, Abud TB, Goyal S, Dana R. Management of High-risk Corneal Transplantation. Surv Ophthalmol 2016;Abstract

The cornea is the most commonly transplanted tissue in medicine. The main cause of corneal graft failure is allograft rejection. The incidence of graft rejection depends on the presence of high-risk characteristics, most notably corneal neovascularization. Although corneal grafting has a high success rates in the absence of these risk factors, high-risk keratoplasty is associated with low success rates because of a high incidence of immune-mediated graft rejection. To improve the survival of high-risk corneal transplantation, various preoperative, intraoperative, and postoperative measures can be considered.; however, the key step in the management of these grafts is the long-term use of local and/or systemic immunosuppressive agents. Although a number of immunosuppressive agents have been employed for this purpose, the results vary significantly across different studies. This is partly due to the lack of an optimized method for their use, as well as the lack of a precise stratification of the degree of risk in each individual patient. New targeted biologic treatments, as well as tolerance-inducing methods, show promising horizons in the management of high-risk corneal transplantation in near future.

BACKGROUND: Immune rejection continues to threaten all tissue transplants. Here we sought to determine whether platelet (P)- and endothelial (E)-selectin mediate T cell recruitment in corneal transplantation and whether their blockade can reduce T cell graft infiltration and improve long-term corneal allograft survival. METHODS: In a murine model of allogeneic corneal transplantation, we used PCR and immunohistochemistry to investigate expression of P- and E-selectin in rejected versus accepted allografts and lymph node flow cytometry to assess expression of selectin ligands by effector T cells. Using P- and E-selectin neutralizing antibodies, we evaluated the effect of blockade on CD4 T cell recruitment, as well as the effect of anti-E-selectin on long-term allograft survival. RESULTS: The P- (93.3-fold, P < 0.05) and E-selectin (17.1-fold, P < 0.005) are upregulated in rejected versus accepted allogeneic transplants. Type 1 T helper cells from hosts with accepted and rejected grafts express high levels of P-selectin glycoprotein ligand 1 and glycosylated CD43. In vivo blockade of P (0.47 ± 0.03, P < 0.05) and E selectin (0.49 ± 0.1, P < 0.05) reduced the number of recruited T cells compared with IgG control (0.98 ± 0.1). Anti-E-selectin reduced the number of mature antigen-presenting cells trafficking to lymphoid tissue compared with control (6.96 ± 0.9 vs 12.67 ± 0.5, P < 0.05). Anti-E-selectin treatment delayed graft rejection and increased survival compared with control, although this difference did not reach statistical significance. CONCLUSIONS: In a model of corneal transplantation, P- and E-selectin mediate T cell recruitment to the graft, E-selectin mediates APC trafficking to lymphoid tissue, and blockade of E-selectin has a modest effect on improving long-term graft survival.

A fully automated and robust method was developed to quantify β-III-tubulin-stained retinal ganglion cells, combining computational recognition of individual cells by CellProfiler and a machine-learning tool to teach phenotypic classification of the retinal ganglion cells by CellProfiler Analyst. In animal models of glaucoma, quantification of immunolabeled retinal ganglion cells is currently performed manually and remains time-consuming. Using this automated method, quantifications of retinal ganglion cell images were accelerated tenfold: 1800 images were counted in 3 h using our automated method, while manual counting of the same images took 72 h. This new method was validated in an established murine model of microbead-induced optic neuropathy. The use of the publicly available software and the method's user-friendly design allows this technique to be easily implemented in any laboratory.

The Clustered, Regularly Interspaced, Short Palindromic Repeats-associated Endonuclease 9 (CRISPR/Cas9)-created MDM2 T309G Mutation Enhances Vitreous-induced Expression of MDM2 and Proliferation and Survival of Cells. J Biol Chem 2016;291(31):16339-47.Abstract

The G309 allele of SNPs in the mouse double minute (MDM2) promoter locus is associated with a higher risk of cancer and proliferative vitreoretinopathy (PVR), but whether SNP G309 contributes to the pathogenesis of PVR is to date unknown. The clustered regularly interspaced short palindromic repeats (CRISPR)-associated endonuclease (Cas) 9 from Streptococcus pyogenes (SpCas9) can be harnessed to manipulate a single or multiple nucleotides in mammalian cells. Here we delivered SpCas9 and guide RNAs using dual adeno-associated virus-derived vectors to target the MDM2 genomic locus together with a homologous repair template for creating the mutation of MDM2 T309G in human primary retinal pigment epithelial (hPRPE) cells whose genotype is MDM2 T309T. The next-generation sequencing results indicated that there was 42.51% MDM2 G309 in the edited hPRPE cells using adeno-associated viral CRISPR/Cas9. Our data showed that vitreous induced an increase in MDM2 and subsequent attenuation of p53 expression in MDM2 T309G hPRPE cells. Furthermore, our experimental results demonstrated that MDM2 T309G in hPRPE cells enhanced vitreous-induced cell proliferation and survival, suggesting that this SNP contributes to the pathogenesis of PVR.

PURPOSE: To evaluate adalimumab as an immunomodulatory treatment for non-infectious ocular inflammatory diseases. METHODS: Characteristics of patients treated with adalimumab were abstracted in a standardized chart review. Main outcomes measured were control of inflammation, corticosteroid-sparing effect, and visual acuity. RESULTS: In total, 32 patients with ocular inflammation were treated with adalimumab. The most common ophthalmic diagnoses were anterior uveitis, occurring in 15 patients (47%), and scleritis, occurring in 9 patients (28%). At 6 months of therapy, among 15 eyes with active inflammation, 7 (47%) became completely inactive, and oral prednisone was reduced to ≤10 mg/day in 2 of 4 patients (50%). On average, visual acuity decreased by 0.13 lines during the first 6 months of treatment. Adalimumab was discontinued because of lack of effectiveness in four patients within 6 months. CONCLUSIONS: Adalimumab was moderately effective in controlling inflammation in a group of highly pre-treated cases of ocular inflammatory disease.

PURPOSE: Management of granulomatosis with polyangiitis (GPA)-associated peripheral ulcerative keratitis (PUK) is challenging and lacks definite guidelines. We aimed to summarize our treatment and outcome experience with patients with GPA-PUK. METHODS: The Massachusetts Eye Research and Surgery Institution patient database was searched from 2005 to 2015 to identify patients with diagnosis of PUK who suffered from GPA. Individual patient histories were examined, and treatment strategies and outcomes were summarized. RESULTS: There were 16 patients who started treatment with a mean duration follow-up of 64 months (range: 12-110 mo). Rituximab and cyclophosphamide, either alone or in combination with other agents, were the most successful agents in controlling inflammation. Rituximab was administered in 11 patients with remission being achieved in all. Cyclophosphamide successfully controlled inflammation in 50% (5/10). Two of the patients (2/5, 40%) who had achieved initial control on cyclophosphamide had flares of their PUK. Two of 11 (18%) patients on rituximab had flares of scleritis and orbital inflammation but not PUK. Two patients, one in each treatment group, stopped treatment after achieving remission after 6 months of therapy but suffered disease recurrence within 2 months of treatment cessation. CONCLUSIONS: Rituximab achieved a high rate of disease control in PUK patients with GPA and is the preferred agent in halting disease progression.

Ebrahimiadib N, Modjtahedi BS, Davoudi S, Foster SC. Treatment of Serpiginous Choroiditis with Chlorambucil: A Report of 17 Patients. Ocul Immunol Inflamm 2016;:1-11.Abstract

PURPOSE: To evaluate the efficacy of chlorambucil in the treatment of serpiginous choroiditis. METHODS: Patient records from the Massachusetts Eye Research and Surgery Institution (MERSI) were reviewed from over the past 10 years. In total, 17 patients with the diagnosis of serpiginous choroiditis treated with chlorambucil were identified. QuantiFERON gold was negative in all of them. Chlorambucil was started at 0.15 mg/kg and dosage was titrated up using weekly white blood cell (WBC) count to achieve a target cell number of 3.0-4.5 × 10(9) cells/L. The goal of therapy was to maintain this value for at least 6-9 months. Adverse effects, recurrence, rate of new choroidal neovascularization (CNVM), and visual acuity before and after treatment were recorded. RESULTS: The mean age of the 17 patients with the diagnosis of serpiginous choroiditis treated with chlorambucil was 46 years, and six patients (35%) were male. The mean duration of treatment for chlorambucil was 8.4 months. None of them developed cancer or persistent side-effects, with a mean follow-up of 53 months. Of the patients, 12 (71%) achieved an average of 45 (5-120) months drug-free remission in their last follow-up. Visual acuity of 33 treated eyes remained within two lines of Snellen acuity in 27 eyes (82%), improved in one eye (3%), and deteriorated in five eyes (15%). Leukopenia was the most common side-effect, which was reversible in all cases. CONCLUSIONS: Chlorambucil in a relatively short duration of time, with an escalating dose guided by weekly WBC was well tolerated, as well as effective in preventing recurrence and maintaining vision in patients with serpiginous choroiditis.

PURPOSE: To compare the efficacy of an internet-based versus traditional referral system for retinopathy of prematurity (ROP) screening in Iran. METHODS: Two referral screening systems were compared in this prospective observational study. Group A (internet-based) comprised premature babies who were registered into an online system for screening. Their appointments were scheduled automatically based on standardized criteria. Group B (conventional) comprised premature babies whose referrals were based on oral or written recommendations. Babies were referred based on standard criteria (gestational age, GA, <37 weeks or birth weight < 3000 g). RESULTS: A total of 2115 neonates were screened between October 2011 and October 2012. From these 1896 met the inclusion criteria (group A n = 856, group B n = 1040). Time of first examination for neonates with GA≤27 weeks was 30.07± 2.72 weeks postmenstrual age in group A and 38.52± 7.03 weeks in group B (p = 0.049), and for neonates with GA>27 weeks was 4.86 ±1.77 and 8.16 ±4.93 weeks after birth in groups A and B, respectively (p < 0.001). All registered babies in group A attended their first screening exam. One case (0.1%) of advanced ROP developed in group A (in a patient with poor follow-up compliance), whereas advanced stages of ROP were seen in 26 cases (2.5%) in group B (p < 0.001). CONCLUSION: An internet-based registration system for ROP screening resulted in fewer cases of delayed first examination and resulted in fewer babies with advanced ROP.

PURPOSE: To describe the clinical and molecular implications of a novel mutation in the NOD2/CARD15 gene on a family and its seven affected members. METHODS: We reviewed the clinical presentations of family members who came to our center for refractory uveitis. Genetic testing and molecular testing was performed. RESULTS: All affected members had adult onset recurrent non-granulomatous panuveitis. The inheritance pattern suggested an autosomal dominant disease and genetic analysis identified a novel mutation in the NOD2 gene that converted amino acid 600 from glutamate to alanine (E600A). Transfection of the E600A NOD2 into human embryonic kidney-293 (HEK293) cells revealed constitutive activation and a reduced ability to respond to the NOD2 ligand, muramyl dipeptide (MDP) as compared with wild-type NOD2. CONCLUSIONS: The E600A mutation in the NOD2 gene may confer a higher penetrance of uveitis but a later onset of milder forms of non-ocular involvement.

Eidet JR, Reppe S, Pasovic L, Olstad OK, Lyberg T, Khan AZ, Fostad IG, Chen DF, Utheim TP. The Silk-protein Sericin Induces Rapid Melanization of Cultured Primary Human Retinal Pigment Epithelial Cells by Activating the NF-κB Pathway. Sci Rep 2016;6:22671.Abstract

Restoration of the retinal pigment epithelial (RPE) cells to prevent further loss of vision in patients with age-related macular degeneration represents a promising novel treatment modality. Development of RPE transplants, however, requires up to 3 months of cell differentiation. We explored whether the silk protein sericin can induce maturation of primary human retinal pigment epithelial (hRPE) cells. Microarray analysis demonstrated that sericin up-regulated RPE-associated transcripts (RPE65 and CRALBP). Upstream analysis identified the NF-κB pathway as one of the top sericin-induced regulators. ELISA confirmed that sericin stimulates the main NF-κB pathway. Increased levels of RPE-associated proteins (RPE65 and the pigment melanin) in the sericin-supplemented cultures were confirmed by western blot, spectrophotometry and transmission electron microscopy. Sericin also increased cell density and reduced cell death following serum starvation in culture. Inclusion of NF-κB agonists and antagonists in the culture medium showed that activation of the NF-κB pathway appears to be necessary, but not sufficient, for sericin-induced RPE pigmentation. We conclude that sericin promotes pigmentation of cultured primary hRPE cells by activating the main NF-κB pathway. Sericin's potential role in culture protocols for rapid differentiation of hRPE cells derived from embryonic or induced pluripotent stem cells should be investigated.

Humans are very adept at extracting the "gist" of a scene in a fraction of a second. We have found that radiologists can discriminate normal from abnormal mammograms at above-chance levels after a half-second viewing (d' ∼ 1) but are at chance in localizing the abnormality. This pattern of results suggests that they are detecting a global signal of abnormality. What are the stimulus properties that might support this ability? We investigated the nature of the gist signal in four experiments by asking radiologists to make detection and localization responses about briefly presented mammograms in which the spatial frequency, symmetry, and/or size of the images was manipulated. We show that the signal is stronger in the higher spatial frequencies. Performance does not depend on detection of breaks in the normal symmetry of left and right breasts. Moreover, above-chance classification is possible using images from the normal breast of a patient with overt signs of cancer only in the other breast. Some signal is present in the portions of the parenchyma (breast tissue) that do not contain a lesion or that are in the contralateral breast. This signal does not appear to be a simple assessment of breast density but rather the detection of the abnormal gist may be based on a widely distributed image statistic, learned by experts. The finding that a global signal, related to disease, can be detected in parenchyma that does not contain a lesion has implications for improving breast cancer detection.

Fadlallah A, Zhu H, Arafat S, Kochevar I, Melki S, Ciolino JB. Corneal Resistance to Keratolysis After Collagen Crosslinking With Rose Bengal and Green Light. Invest Ophthalmol Vis Sci 2016;57(15):6610-6614.Abstract

Purpose: The purpose of this study was to evaluate the resistance to degradation by collagenase A of corneas that have been crosslinked with Rose Bengal and green light (RGX). Methods: The ex vivo crosslinking procedure was performed on enucleated rabbit corneas. Corneas were deepithelialized after applying 30% alcohol. Corneas were stained with Rose Bengal (RB, 0.1%) for 2 minutes and then exposed to green light (532 nm) at 0.25 W/cm2 for times to deliver doses of 50, 100, 150, or 200 J/cm2 (n = 5 per group). Five corneas were pretreated with riboflavin solution (0.1% riboflavin) for 15 minutes and irradiated with ultraviolet A (UVA) light (370 nm, 3 mW/cm2) for 30 minutes. Five corneas underwent only de-epithelialization and were otherwise untreated. Five corneas were stained with RB without light exposure. The central corneas of each group was removed with a 8.5-mm trephine and incubated at 37°C in 0.3% collagenase A solution. Time to dissolution of each cornea was compared across treatments. Results: Corneas treated with RGX were treated with light fluences of 50, 100, 150, and 200 J/cm2; these corneas dissolved completely at 8.3 ± 1.2, 11.1 ± 1.4, 12.4 ± 1.7, and 15.7 ± 1.8 hours, respectively. Corneas treated by riboflavin and UVA light dissolved at 15.7 ± 1.7 hours, and nontreated corneas dissolved at 6.1 ± 1.3 hours. Corneas treated with only RB (no green light) dissolved at 9.3 ± 1.7 hours. Compared with the untreated corneas, all of the RB groups and the riboflavin-UVA-treated group of corneas degraded statistically significantly slower than untreated corneas (P < 0.05). Conclusions: Crosslinking with RGX increased corneal resistance to digestion by collagenase comparable to that produced by riboflavin and UVA treatment.

Scleritis and uveitis are potentially blinding conditions that can be associated with systemic inflammatory diseases. Polymyalgia rheumatica (PMR) is a common rheumatic disorder of the elderly of uncertain etiology. Although there are a few published reports of scleritis and uveitis in PMR patients, the association of PMR to ocular inflammation has not been well established. The aim of this study is to report a series of PMR patients with scleritis and/or uveitis and review the prior published reports of this potential association. We retrospectively reviewed the medical charts of patients with PMR and scleritis or uveitis who were examined in the Ocular Immunology Service of Massachusetts Eye and Ear Infirmary. We also performed a systematic literature search (PubMed; January 1990 until January 2014) to identify earlier published reports. Seven PMR patients with ocular inflammatory disease (OID) were included in our study: two with scleritis, three with anterior uveitis, and two with panuveitis. The onset of PMR preceded the occurrence of OID in six patients, and in one patient uveitis developed 2 months prior to PMR. Five patients demonstrated a temporal association between flares of PMR and OID. In four patients, OID flares developed during tapering of systemic prednisone prescribed for PMR. Four of the five patients who had relapsing PMR had recurrent or persistent uveitis over the course of follow-up. PMR may be associated with both scleritis and uveitis and should be considered as a possible underlying cause of OID.

Field MG, Alasil T, Baniasadi N, Que C, Simavli H, Sobeih D, Sola-Del Valle D, Best MJ, Chen TC. Facilitating Glaucoma Diagnosis With Intereye Retinal Nerve Fiber Layer Asymmetry Using Spectral-Domain Optical Coherence Tomography. J Glaucoma 2016;25(2):167-76.Abstract

PURPOSE: To test whether increased intereye retinal nerve fiber layer (RNFL) asymmetry may be indicative of glaucoma. To determine the best statistical methods and intereye RNFL cutoffs for differentiating between normal and glaucoma subjects to better alert clinicians to early glaucomatous damage. METHODS: Sixty-six primary open-angle glaucoma (OAG) and 40 age-matched normal subjects had both eyes imaged at the Massachusetts Eye and Ear Infirmary with a commercially available spectral-domain optical coherence tomography (OCT) machine. Statistical methodologies were used to find cutoffs that achieved the best sensitivities and specificities for differentiating OAG from normal subjects. RESULTS: Intereye RNFL asymmetry for global average, all quadrants, and all sectors was significantly greater in OAG than normal subjects. Intereye RNFL asymmetry for global average showed the greatest statistical difference (P<0.001) between OAG (23.64±14.90 μm) and normal eyes (3.58±3.96 μm), with 6.60 times greater asymmetry in OAG eyes. The inferior quadrant showed the second greatest difference, with 3.91 times greater asymmetry in OAG eyes. Using a statistically determined cutoff of 6.0 μm as abnormal, intereye RNFL asymmetry for global average achieved a sensitivity of 74.24% and specificity of 90% in differentiating between normal and OAG subjects, achieving a better combination of sensitivity and specificity than intereye RNFL asymmetry of any quadrant or sector. CONCLUSIONS: Intereye RNFL asymmetry may be a useful clinical OCT measurement to provide quantitative assessment of early glaucomatous damage. Newly developed algorithms for intereye RNFL asymmetry may improve the ability to detect glaucoma.

OBJECTIVES: To assess resident cataract surgery outcomes at an academic teaching institution using 2 Physician Quality Reporting System (PQRS) cataract measures, which are intended to serve as a proxy for quality of surgical care. DESIGN: A retrospective review comparing cataract surgery outcomes of resident and attending surgeries using 2 PQRS measures: (1) 20/40 or better best-corrected visual acuity following cataract surgery and (2) complications within 30 days following cataract surgery requiring additional surgical procedures. SETTING: An academic ophthalmology center. PARTICIPANTS: A total of 2487 surgeries performed at the Massachusetts Eye and Ear Infirmary from January 1, 2011 to December 31, 2012 were included in this study. RESULTS: Of all 2487 cataract surgeries, 98.95% achieved a vision of at least 20/40 at or before 90 days, and only 0.64% required a return to the operating room for postoperative complications. Of resident surgeries, 98.9% (1370 of 1385) achieved 20/40 vision at or before 90 days follow-up. Of attending surgeries, 99.0% (1091 of 1102) achieved 20/40 vision at or before 90 days (p = 1.00). There were no statistically significant differences between resident and attending cases regarding postoperative complications needing a return to the operating room (i.e., 0.65%, or 9 of 1385 resident cases vs 0.64%, or 7 of 1102 attending cases; p = 1.00). CONCLUSIONS: Using PQRS Medicare cataract surgery criteria, this study establishes new benchmarks for cataract surgery outcomes at a teaching institution and supplemental measure for assessing resident surgical performance. Excellent cataract outcomes were achieved at an academic teaching institution, with results exceeding Medicare thresholds of 50%. There appears to be no significant difference in supervised trainee and attending cataract surgeon outcomes using 2 PQRS measures currently used by Medicare to determine physician reimbursement and quality of care.
