Wang F, Liu LQ, Liang RB, Zhang LJ, Shu HY, Liao XL, Pan YC, Wu J, Su T, Shao Y. Decreased Macular Retinal Thickness in Patients With Pterygium. Front Neurol 2022;13:881190.Abstract
Purpose: To explore alterations in macular retinal thickness (RT) and analyze correlation between macular RT and pterygium area, length in pterygium patients. Methods: Totally 13 patients with pterygium (left eye) and 13 healthy controls (left eye) were recruited. OCTA was applied to scan each eye to generate three-dimensional images. Based on the Early Treatment Diabetic Retinopathy Study (ETDRS) method, each image was divided into nine subregions for the ETDRS: central (C); inner superior (IS); outer superior (OS); inner nasal (IN); outer nasal (ON); inner inferior (II); outer inferior (OI); inner temporal (IT); and outer temporal (OT). The macular RT in each subregion was measured. Furthermore, the correlation between RT and the area, length of pterygium was analyzed. Results: The visual acuity of pterygium patient was different from that of the control (P < 0.05). Besides, decreased intraretinal thickness of the IN and ON, increased intraretinal thickness of OT, decreased extraretinal thickness of OT, IN, ON, OS, and decreased retinal full layer thickness of medial superior, OS, IN, ON, and II subregions in pterygium group were observed. There was a negative correlation between RT of the IN and ON subregions and the length of pterygium (r = -0.5803 and r = -0.6013, P = 0.0376 and P = 0.0297). The RT of IN subregion was negatively correlated with pterygium area (r = -0.5844, P = 0.0359). According to the receiver operating characteristic analysis, in the ON subregion, the areas under the curve of the inner retinal thickness, outer retinal thickness and the whole retinal thickness were 1.0 (95% CI: 1.0), 0.882 (95% CI: 0.715 and 0.963), and 1.0 (95% CI: 1.0). The smallest area under the curve of retinal thickness in OT subregion was 0.018 (95% CI: 0-0.059). Conclusion: RT of pterygium patients was significantly decreased, and the main alterations occurred in the temporal side suggesting there might exist retinal structural alterations in pterygium.
Sekimitsu S, Wang J, Elze T, Segrè AV, Wiggs JL, Zebardast N. Interaction of background genetic risk, psychotropic medications, and primary angle closure glaucoma in the UK Biobank. PLoS One 2022;17(6):e0270530.Abstract
BACKGROUND/AIMS: Psychotropic medications have been reported as a risk factor for angle closure disease. However, the interaction between background genetic risk for primary angle closure glaucoma (PACG) and susceptibility to angle closure disease among psychotropic medication users has not been investigated. Here we demonstrate the utility of a genome-wide polygenic risk score (PRS) in identifying and risk-stratifying subjects with PACG and investigate the association between PACG genetic burden and exposure to psychotropic medications on prevalent angle closure. METHODS: This analysis used the UK Biobank dataset, a prospective cohort study of 502,506 UK residents. We constructed a PACG PRS for participants using genome-wide association study summary statistics from a multiethnic meta-analysis using the Lassosum method. RESULTS: Among the 441,054 participants, 959 (0.22%) were identified as PACG cases. Individuals with PACG had higher PRS compared to those without PACG (0.24±1.03 SD vs. 0.00±1.00 SD, p<0.001) and PACG prevalence increased with each decile of higher PRS. Among individuals using psychotropic medication, those with PACG had higher average PRS (0.31±1.00 SD vs. 0.00±1.00 SD, p<0.001) and were more likely to have a PRS in upper deciles of polygenic risk (p = 0.04). At each decile of PRS, psychotropic medication use was associated with increased risk of PACG. These effects were more pronounced and significant in higher deciles. CONCLUSION: We demonstrate the utility of a PRS for identifying individuals at higher risk of PACG. Additionally, we demonstrate an important relationship where the association between psychotropic medications use and PACG diagnosis varies across the polygenic risk spectrum.

Adeno-Associated Virus Serotype 2-hCHM Subretinal Delivery to the Macula in Choroideremia: Two-Year Interim Results of an Ongoing Phase I/II Gene Therapy Trial. Ophthalmology 2022;129(10):1177-1191.Abstract
PURPOSE: To assess the safety of the subretinal delivery of a recombinant adeno-associated virus serotype 2 (AAV2) vector carrying a human choroideremia (CHM)-encoding cDNA in CHM. DESIGN: Prospective, open-label, nonrandomized, dose-escalation, phase I/II clinical trial. PARTICIPANTS: Fifteen CHM patients (ages 20-57 years at dosing). METHODS: Patients received uniocular subfoveal injections of low-dose (up to 5 × 1010 vector genome [vg] per eye, n = 5) or high-dose (up to 1 × 1011 vg per eye, n = 10) of a recombinant adeno-associated virus serotype 2 (AAV2) vector carrying a human CHM-encoding cDNA (AAV2-hCHM). Patients were evaluated preoperatively and postoperatively for 2 years with ophthalmic examinations, multimodal retinal imaging, and psychophysical testing. MAIN OUTCOME MEASURES: Visual acuity, perimetry (10-2 protocol), spectral-domain OCT (SD-OCT), and short-wavelength fundus autofluorescence (SW-FAF). RESULTS: We detected no vector-related or systemic toxicities. Visual acuity returned to within 15 letters of baseline in all but 2 patients (1 developed acute foveal thinning, and 1 developed a macular hole); the rest showed no gross changes in foveal structure at 2 years. There were no significant differences between intervention and control eyes in mean light-adapted sensitivity by perimetry or in the lateral extent of retinal pigment epithelium relative preservation by SD-OCT and SW-FAF. Microperimetry showed nonsignificant (< 3 standard deviations of the intervisit variability) gains in sensitivity in some locations and participants in the intervention eye. There were no obvious dose-dependent relationships. CONCLUSIONS: Visual acuity was within 15 letters of baseline after the subfoveal AAV2-hCHM injections in 13 of 15 patients. Acute foveal thinning with unchanged perifoveal function in 1 patient and macular hole in 1 patient suggest foveal vulnerability to the subretinal injections. Longer observation intervals will help establish the significance of the minor differences in sensitivities and rate of disease progression observed between intervention and control eyes.

PURPOSE: Dry eye disease (DED) is a common age-related ocular surface disease. However, it is unknown how aging influences the ocular surface microenvironment. This systematic review aims to investigate how the aging process changes the ocular surface microenvironment and impacts the development of DED. METHODS: An article search was performed in PubMed, EMBASE, and Web of Science. 44 studies reporting on age-related ocular changes and 14 large epidemiological studies involving the prevalence of DED were identified. 8 out of 14 epidemiological studies were further analyzed with meta-analysis. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines were followed. Study-specific estimates (impact of aging on the prevalence of DED) were combined using one-group meta-analysis in a random-effects model. RESULTS: Meta-analysis revealed the prevalence of DED in the elderly aged 60 years old or older was 5519 of 60107 (9.2%) and the odds ratio of aging compared to younger age was 1.313 (95% confidence interval [CI]; 1.107, 1.557). With increasing age, the integrity of the ocular surface and tear film stability decreased. Various inflammatory cells, including senescent-associated T-cells, infiltrated the ocular surface epithelium, lacrimal gland, and meibomian gland, accompanied by senescence-related changes, including accumulation of 8-OHdG and lipofuscin-like inclusions, increased expression of p53 and apoptosis-related genes, and decreased Ki67 positive cells. CONCLUSIONS: The aging process greatly impacts the ocular surface microenvironment, consequently leading to DED.
Madjedi KM, Stuart KV, Chua SYL, Foster PJ, Strouthidis NG, Luben RN, Warwick AN, Kang JH, Wiggs JL, Pasquale LR, Khawaja AP. The Association of Female Reproductive Factors with Glaucoma and Related Traits: A Systematic Review. Ophthalmol Glaucoma 2022;5(6):628-647.Abstract
TOPIC: This systematic review summarizes evidence for associations between female reproductive factors (age at menarche, parity, oral contraceptive [OC] use, age at menopause, and postmenopausal hormone [PMH] use) and intraocular pressure (IOP) or open-angle glaucoma (OAG). CLINICAL RELEVANCE: Understanding the associations between female reproductive factors and glaucoma may shed light on the disease pathogenesis and aid clinical prediction and personalized treatment strategies. Importantly, some factors are modifiable, which may lead to new therapies. METHODS: Two reviewers independently extracted articles in MEDLINE, Embase, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials databases to identify relevant studies. Eligibility criteria included studies with human subjects aged > 18 years; a measured outcome of either IOP or OAG; a cohort, case-control, cross-sectional, or randomized controlled trial design; a reported measure of association, such as the hazard ratio, relative risk, odds ratio, or mean difference, with an associated confidence interval; and a measured exposure of at least 1 of the following variables: age at menarche, parity, OC use, age at menopause, or PMH use. RESULTS: We included a total of 27 studies. Substantial differences in study designs, exposure and treatment levels, treatment durations, and variable reporting precluded a meaningful quantitative synthesis of the identified studies. Overall, relatively consistent associations between PMH use and a lower IOP were identified. Estrogen-only PMH use may be associated with lower OAG risk, which may be modified by race. No significant associations were found with combined estrogen-and-progesterone PMH use. No strong associations between parity or age at menarche and glaucoma were found, but a younger age at menopause was associated with an increased glaucoma risk, and adverse associations were identified with a longer duration of OC use, though no overall association with OC use was found. CONCLUSIONS: The association between PMH use and lower IOP or OAG risk is a potentially clinically relevant and modifiable risk factor and should be investigated further, although this needs to be interpreted in the context of a high risk of bias across included studies. Future research should examine associations with IOP specifically and how the relationship between genetic factors and OAG risks may be influenced by female reproductive factors.
Elhusseiny AM, Saeed HN. Posterior Polymorphous Corneal Dystrophy in a Pediatric Population. Cornea 2022;41(6):734-739.Abstract
PURPOSE: The aim of this study was to evaluate the clinical and topographic features of posterior polymorphous corneal dystrophy (PPCD) in children aged 15 years or younger with a long-term follow-up. Retrospective case series. METHODS: A retrospective chart review of patients who were diagnosed with PPCD at Boston Children's Hospital from 1999 to 2020 was performed. Data collected included age at the time of diagnosis, slit lamp findings, cycloplegic refraction, best-corrected visual acuity, central corneal thickness, specular microscopy, and corneal topography findings whenever available. RESULTS: Twenty-seven eyes of 19 patients were included (11 unilateral and 8 bilateral cases). Ten patients were girls (52.6%). Left eye was affected in 14 eyes. The mean age at the time of diagnosis was 8.5 ± 3.3 years, with a mean follow-up of 5.3 years. In unilateral cases, there was a statistically significant difference in the endothelial cell density (P = 0.01), coefficient variation (P = 0.03), and hexagonality (P = 0.01) between the affected and the contralateral unaffected eyes. The mean best-corrected visual acuity at initial presentation was 0.8 ± 0.2 compared with 0.9 ± 0.08 in unaffected eyes (P = 0.04). The mean astigmatism was higher in the affected eye (+1.7 diopters) compared with (+1.00) the unaffected eye (P = 0.07). At initial presentation, 7 of 27 eyes had amblyopia, which resolved, either partially or completely, in 5 eyes after treatment. CONCLUSIONS: PPCD can present early in children with astigmatism and anisometropic amblyopia. A careful slit lamp examination for children presenting with anisoastigmatism is necessary to diagnose PPCD. Contrary to adults, presentation is often unilateral. Such patients should be followed up regularly with cycloplegic retinoscopy to prevent and treat refractive amblyopia if present.
Jiro MC, Sigua M, Ivey SL, Maus M, Hennein L, Dio M, Cocohoba J. Ang Ating Mata: Disparities in Eye Health Knowledge, Attitudes and Practices among Older Adult Filipino-Americans in the San Francisco Bay Area Counties. J Immigr Minor Health 2022;Abstract
Filipino-Americans are the third largest Asian-American population, with a median age of 44. However, there is limited literature focusing on the group's ophthalmic care engagement. Timely eye examinations and outreach are necessary to reduce visual impairment in this older community. To assess eye care knowledge, attitudes, and practices, we conducted a cross-sectional study surveying Filipino-Americans within the nine San Francisco Bay Area counties. Associations between primary outcomes and sociodemographic factors were analyzed using chi-squared analysis and student's T-test. In our convenience sample of 256 surveys, a majority of participants are receiving appropriate eye care; those that lacked health and eye insurance, immigrated and are lower income did not receive optimal eye care. Study participants also demonstrated a lack of awareness of eye diseases and risk factors. Our results suggest that culturally sensitive eye health education materials are lacking and should be made accessible for this large and rapidly growing population.
Buch KA, Bouffard MA, Kardon RH, Wills A-MA, Privitera CM, Sharma M, Wray SH. Clinical Correlation Between Vertical Gaze Palsy and Midbrain Volume in Progressive Supranuclear Palsy. J Neuroophthalmol 2022;42(2):246-250.Abstract
BACKGROUND: Supranuclear vertical gaze palsies and slowed vertical saccades are characteristic clinic features of progressive supranuclear palsy (PSP). The "hummingbird sign," reflective of midbrain atrophy, is a classic radiographic sign of PSP. Correlation between eye movement abnormalities and radiographic findings in PSP has been reported previously. However, due to the use of clinical criteria not commonly employed in neuro-ophthalmic practice and neuroimaging techniques that are not widely available, it remains unclear whether correlation between midbrain structure and characteristic ocular-motor disturbances can be helpful to neuro-ophthalmologists seeking to adjudicate difficult or unusual diagnostic cases. METHODS: Patients with a diagnosis of probable PSP according to Movement Disorders Society criteria were studied retrospectively. A neuroradiologist calculated brainstem volumes in enrolled participants and normal controls. Spearman correlations were used to correlate the extent of eye movement limitation as assessed by 2 neuro-ophthalmologists with brainstem volumes. RESULTS: Fourteen participants with PSP and 15 healthy controls with similar age and gender distribution were enrolled and evaluated retrospectively. All 14 participants with PSP had undergone MRIs. Midbrain atrophy significantly correlated with the PSP rating scale (P < 0.001). PSP patients had significantly reduced volumes in the midbrain (P -0.0026), tegmentum (0.0001), tectum (0.0001), and medulla (P = 0.0024) compared with normal controls. Notes documenting quantified ocular motor function were available in 7 of 14 participants with PSP. Midbrain atrophy significantly correlated with in the extent of upward gaze limitation (P = 0.03). CONCLUSIONS: The severity of upward gaze limitation correlates with the severity of midbrain atrophy in patients with PSP. Recognition of this correlation may help to adjudicate diagnostic dilemmas and guide further evaluation.

The Prevalence of Retinal Disease and Associated Central Nervous System Disease in Young Patients with Incontinentia Pigmenti. Ophthalmol Retina 2022;Abstract
PURPOSE: To evaluate the prevalence of retinal disease on fluorescein angiography (FA) in patients with incontinentia pigmenti (IP) and to compare the severity of retinal disease in those with and without known central nervous system (CNS) disease. DESIGN: Multi-institutional consecutive retrospective case series SUBJECTS: New patients with a diagnosis of IP seen at the Casey Eye Institute, Oregon Health and Science University, Moran Eye Center, University of Utah, Wills Eye Hospital, or Bascom Palmer Eye Institute, University of Miami from December 2011 to September 2018. METHODS: Detailed ophthalmoscopic examination and FA were recommended to all new patients and performed on every patient who had parental consent. Ophthalmoscopic findings and FA images were graded for severity by two masked graders on a 3-point scale: 0 = no disease, 1 = vascular abnormalities without leakage, 2 = leakage or neovascularization, 3 = retinal detachment. Presence of known CNS disease was documented. Additional cases were obtained from a pediatric retina listserv for examples of phenotypic variation. MAIN OUTCOME MEASURES: Proportion of eyes noted to have disease on ophthalmoscopy compared with FA. Severity of retinal disease in those with and without known CNS disease. RESULTS: Retinal pathology was detected in 18/35 (51%) by indirect ophthalmoscopy and 26/35 (74%) by FA (p=0.048) in a predominantly pediatric population (median age = 9 months). Ten patients (29%) had known CNS disease at the time of the eye exam. A Wilcoxon ranked sums test indicated that the retinal severity scores for patients with CNS disease (median = 2) were significantly higher than the retinal severity scores for patients without CNS disease (median = 1), z = -2.12, p = 0.034. CONCLUSION: Retinal disease is present in the majority of patients with IP, and the ophthalmoscopic examination is less sensitive than FA for detection of disease. There may be a correlation between the severity of retinal and CNS disease.

Nasal Transposition of the Split Lateral Rectus Muscle for Strabismus Associated With Bilateral 3rd-Nerve Palsy. Am J Ophthalmol 2022;242:165-172.Abstract
PURPOSE: To determine the success rate and complications associated with nasal transposition of the split lateral rectus muscle (NTSLR) for treating bilateral 3rd-nerve palsy. DESIGN: Retrospective, interventional case series. METHODS: An international, multicenter registry was used for the study. The study population was all patients with bilateral 3rd-nerve palsy treated with NTSLR. Sensorimotor evaluations were conducted before and 6 months after unilateral or bilateral NTSLR. Outcome measures were postoperative horizontal alignment ≤15 prism diopters (PD), intraoperative technical difficulties, and vision-threatening complications. The association of patient demographics and surgical technique with each outcome was analyzed using multivariable logistic regression. RESULTS: A total of 34 patients were included, with a median age of 46 years (interquartile range [IQR] = 25-54 years) at surgery. The most common etiologies were ischemic (29%), neoplastic (15%), and congenital (12%). NTSLR performed unilaterally with alternative surgery on the opposite eye (65%) resulted in a median postoperative exotropia of 18 PD (IQR = 7-35 PD), and when performed bilaterally (35%) resulted in postoperative exotropia of 14 PD (IQR = 5-35 PD). Success was achieved in 50% of cases, intraoperative technical difficulties were reported in 18%, and vision-threatening complications occurred in 21%. Attachment of the lateral rectus muscle ≥10 mm posterior to the medial rectus insertion was associated with increased vision-threatening complications (odds ratio = 9.0; 95% CI = 1.3-99). CONCLUSIONS: NTSLR can address the large-angle exotropia associated with bilateral 3rd-nerve palsy. Surgeons should be aware that posterior placement of the lateral rectus muscle may increase the risk of vision-threatening complications, particularly serous choroidal effusion.
Liebman DL, Tam EK, Lithgow MY, Kane JE, Fischbein NJ, Lefebvre DR, Chwalisz BK, Gaier ED. Optic Perineuritis Associated With Cryptococcal Meningitis Presenting With a "Hot Orbit" in a Patient With Chronic Lymphocytic Leukemia. J Neuroophthalmol 2022;42(2):272-277.Abstract
ABSTRACT: A 75-year-old man presented with 3 days of progressive left retro-orbital pain, eyelid swelling, tearing, and pain with extraocular movement. His medical history was significant for type II diabetes mellitus and chronic lymphocytic leukemia, stable on no therapy since diagnosis 8 years prior. The initial examination was significant for diffuse restriction of left ocular motility, marked lid edema, and mild dyschromatopsia. Computed tomography demonstrated asymmetric left periorbital soft tissue swelling and intraconal fat stranding with an irregular left optic nerve sheath complex and clear paranasal sinuses. He was hospitalized for orbital cellulitis and treated empirically with broad-spectrum intravenous antibiotics, but his visual acuity declined over the ensuing 2 days. Subsequent MRI demonstrated left-greater-than-right circumferential optic nerve sheath enhancement, and leptomeningeal enhancement. An orbital biopsy demonstrated monoclonal B-cell lymphocyte aggregation, whereas a lumbar puncture was positive for Cryptococcus antigen with subsequent demonstration of abundant Cryptococcus by Papanicolaou stain. The final diagnosis was optic perineuritis secondary to cryptococcal meningitis presenting with orbital inflammation. Although his clinical course was complicated by immune reconstitution inflammatory syndrome, symptoms and signs of optic neuropathy ultimately resolved after 1 month of intensive antifungal therapy.
