Panayi AC, Wu M, Liu Q, Haug V, Yu Z. The Rising Interest in Canthoplasty: An Analysis of Online Search Trends. J Craniofac Surg 2020;Abstract
Canthoplasty as a cosmetic procedure appears to be on the rise in the West. Online search query data offers a powerful tool for analyzing population trends, including changes in patient interest in surgical procedures. Cosmetic surgeons can utilize the internet to increase patient education and interest, as well as to provide information and address misinformation. In this study we sought to verify the increase in cosmetic canthoplasty, for the first time, through analysis of Internet search data, and to establish trends in the interest of Internet users for cosmetic canthoplasty. These trends were subsequently compared with trends in literature publication to establish whether there is a correlation between patient and surgeon interest in the procedure.
Charles NC, Jakobiec FA, Sherwood P, Belinsky I. Multicameral Steatocystoma Simplex of the Caruncle. Ophthalmic Plast Reconstr Surg 2020;Abstract
A yellow cyst of the caruncle in a 68-year-old man displayed the characteristic sebaceous glands and sebocytes of steatocystoma within the cyst wall, with a unique configuration of multiple branching compartments. The cyst lining was of trichilemmal character, lacking a keratohyalin granular layer, and replicated the immunohistochemical characteristics of a previously reported caruncular steatocystoma with the exception of a positive trichilemmal marker, calretinin, in the present case. Four previous cases of caruncular steatocystoma have been described, only one of which incorporated immunohistochemical analysis. Steatocystoma develops from a sebaceous gland duct, which displayed in this case multiple chambers subdividing what is usually a single round lumen.
Dohlman JC, Cestari DM, Freitag SK. Orbital disease in neuro-ophthalmology. Curr Opin Ophthalmol 2020;31(6):469-474.Abstract
PURPOSE OF REVIEW: Orbital disease represents a diverse spectrum of pathology and can result in a variety of neuro-ophthalmic manifestations. The aim of this review is to provide updates on recent advances in our understanding of orbital disease secondary to thyroid eye disease, myositis, IgG4-related disease, sarcoidosis, granulomatosis with polyangiitis and various tumours. RECENT FINDINGS: With regards to thyroid eye disease, there have been recent advances in the development of steroid-sparing therapies, new modalities for objectively monitoring disease activity and increased understanding of the role of environmental risk factors. There has been interest in characterizing the clinical course and underlying mechanism of optic nerve disease secondary to orbital disorders, which has led to advances in how we monitor for and prevent permanent vision loss. Increased knowledge of orbital tumour subtype histopathology and the development of novel classification systems has had prognostic value and aided medical decision-making. SUMMARY: Orbital disease occurs secondary to a wide variety of diseases and can lead to neuro-ophthalmic manifestations with significant morbidity. Advances in our understanding of different subtypes of orbital disease have improved our ability to treat these potentially debilitating conditions.
Rossin EJ, Szypko C, Giese I, Hall N, Gardiner MF, Lorch A. Factors Associated With Increased Risk of Serious Ocular Injury in the Setting of Orbital Fracture. JAMA Ophthalmol 2020;Abstract
Importance: Orbital fractures are common in ocular trauma, and there is a need to develop predictive tools to estimate risk of concurrent ocular injury. Objective: To identify clinical and radiographic features that are associated with increased risk of substantial ocular injury in the setting of orbital fracture. Design, Setting, and Participants: Retrospective consecutive case series of patients who sustained orbital fractures between 2012 and 2018. Examinations were done at 1 of 2 level 1 trauma centers in the emergency or inpatient setting. A total of 430 consecutive patients (500 eyes) between 2012 and 2017 met inclusion criteria for the training sample. After building a predictive model, 88 additional consecutive patients (97 eyes) between 2017 and 2018 who met inclusion criteria were collected as a test sample. Main Outcomes and Measures: The primary outcome measure was substantial ocular injury distinct from orbital fracture. Results: The mean age of our patient population was 53.5 years (range, 16-100 years). The overall rate of substantial ocular injury was 20.4%, and the rate of injury requiring immediate ophthalmic attention was 14.4%. Five variables were found to be associated with increased risk of substantial ocular injury: blunt trauma with a foreign object (odds ratio [OR], 19.4; 95% CI, 6.3-64.1; P < .001), inability to count fingers (OR, 10.1; 95% CI, 2.8-41.1; P = .002), roof fracture (OR, 9.1; 95% CI, 2.8-30.0; P = .002), diplopia on primary gaze (OR, 6.7; 95% CI, 1.7-25.1; P = .003), and conjunctival hemorrhage or chemosis (OR, 4.2; 95% CI, 2.2-8.5; P < .001). The results were translated into a bedside tool that was tested in an independent group of eyes (n = 97) and found to be associated with substantial ocular injury with a 95% sensitivity (95% CI, 77.2-99.9), 40% specificity (95% CI, 28.9-52.0), 31.8% positive predictive value (95% CI, 27.5-36.5), and 96.8% negative predictive value (95% CI, 81.3-99.5). Conclusions and Relevance: A minority of patients with an orbital fracture had a substantial ocular injury. Certain radiographic and clinical findings were associated with substantial ocular injury. Testing of the algorithm in prospective longitudinal settings appears warranted.
Jafari A, Lehmann AE, Wolkow N, Juliano AF, Bleier BS, Reinshagen KL. Radioanatomic Characteristics of the Posteromedial Intraconal Space: Implications for Endoscopic Resection of Orbital Lesions. AJNR Am J Neuroradiol 2020;Abstract
BACKGROUND AND PURPOSE: Imaging is essential in the diagnostic work-up of patients with orbital lesions. The position of an orbital lesion relative to the inferomedial muscular trunk of the ophthalmic artery determines endoscopic resectability, anticipated technical difficulty, and patient morbidity. Although the inferomedial muscular trunk is not readily identifiable on preoperative imaging, we hypothesize that it is spatially approximate to the location where the ophthalmic artery crosses the optic nerve. Our aim was to determine whether the ophthalmic artery-optic nerve crosspoint anatomically approximates the inferomedial muscular trunk in a cadaver study and can be appreciated on imaging of known posteromedial orbital lesions. MATERIALS AND METHODS: Dissection was performed on 17 fresh-frozen cadaver orbits to assess the relationship between the inferomedial muscular trunk and ophthalmic artery-optic nerve crosspoint. Retrospective review of imaging in 9 patients with posteromedial orbital lesions assessed posteromedial orbital compartment characteristics and the ability to locate the ophthalmic artery-optic nerve crosspoint. RESULTS: In our cadaver study, the mean distance between the ophthalmic artery-optic nerve crosspoint and the inferomedial muscular trunk was 1.21 ± 0.64 mm. Retrospectively, the ophthalmic artery-optic nerve crosspoint was identifiable in 9/9 patients, whereas the inferomedial muscular trunk was not identifiable in any patient. Total or partial effacement of the posteromedial intraconal fat triangle was observed in 9/9 patients. CONCLUSIONS: This study of neurovascular relationships within the posteromedial orbit demonstrates that the ophthalmic artery-optic nerve crosspoint closely approximates the inferomedial muscular trunk and can be seen in patients with posteromedial orbital lesions. Posteromedial intraconal fat effacement may help to localize these lesions. These findings may facilitate multidisciplinary communication and help predict lesion resectability and patient outcomes.
Pennington JD, Bleier BS, Freitag SK. Endoscopic endonasal resection of orbital schwannoma assisted with small-incision medial orbitotomy: case series and surgical technique. Orbit 2020;:1-7.Abstract
PURPOSE: To describe a surgical approach for the resection of schwannomas occurring in the medial aspect of the orbit and to review a series of patients who underwent this novel technique. METHODS: This retrospective, non-comparative case series presents the surgical technique and outcomes of patients who underwent removal of a medial orbital schwannoma via an endoscopic endonasal approach combined with a small-incision medial orbitotomy by a team of two surgeons (BSB and SKF). Patient demographics, pre- and post-operative clinical examination findings, visual field testing, and radiographic studies were reviewed. Operative reports were reviewed for technical details and complications. RESULTS: The patients included a 12 year-old male, 73 year-old female and 8 year-old male. Indications for surgery included: decreased visual acuity, diplopia, proptosis and Humphrey visual field (HVF) deficit, in the presence of a medial orbital biopsy-proven schwannoma. The surgical approach in all three patients was primarily endoscopic endonasal. Additionally, two had transcaruncular orbitotomies and one had a small-incision medial lid crease orbitotomy to assist with lateral tumor dissection. Tumor resection was complete in one case and near-total in two cases. There were no intra-operative surgical complications. Average resected specimen volume was 3.41 cm ± 2.20. All patients had post-operative improvement in visual acuity (VA) and proptosis. Post-operative follow-up intervals were 27.5 months, 12.3 months and 3.5 months, respectively. CONCLUSION: Resection of orbital schwannomas using an endoscopic endonasal approach with small-incision medial transorbital assistance is a safe and effective option for a multidisciplinary surgical team.
Milman T, Jakobiec FA, Lally SE, Shields JA, Shields CL, Eagle RC. Lacrimal Gland Hamartoma (Formerly Termed Dacryoadenoma). Am J Ophthalmol 2020;217:189-197.Abstract
PURPOSE: Since the original description of "dacryadenoma" by Jakobiec and associates, the data on this unusual epibulbar lacrimal gland lesion remain sparse. The aim of this study was to characterize clinically, morphologically, and immunohistochemically this isolated epibulbar lacrimal gland lesion. DESIGN: Retrospective observational case series. METHODS: Institutional pathology records between 2000 and 2019 were searched for all cases of isolated epibulbar lacrimal gland lesions. Tissue from 3 normal lacrimal glands and 1 complex choristoma were included for comparative analysis. Clinical, histopathologic, and immunohistochemical findings were recorded. RESULTS: Four patients with isolated epibulbar lacrimal gland lesions, 2 male and 2 female, with a median age of 18 years (range, 12-57) were identified. All patients presented with recent onset of unilateral pink-to-orange, well-circumscribed subepithelial juxtaforniceal (3/4, 75%), or nasal (1/4, 25%) bulbar conjunctival nodules, which were asymptomatic (3/4, 75%) or associated with foreign body sensation (1/4, 25%). When compared with the normal lacrimal gland and complex choristoma, all isolated epibulbar lacrimal gland lesions were composed predominantly of variably dilated, branching tubular structures with pseudo-apocrine snouts, and either totally absent (2/2, 50%) or rare (2/2, 50%) ducts and rare acinar zymogen granules (3/4, 75%). CONCLUSION: Our study confirms that a subset of isolated epibulbar lacrimal gland lesions differs morphologically and immunohistochemically from normal lacrimal gland tissue and the lacrimal gland in a complex choristoma. These differences range from subtle to overt, suggesting that isolated epibulbar lacrimal gland lesions may have originated from precursor cellular elements indigenous to the conjunctiva (hamartia) and grew into disorganized lacrimal gland tissue.
Franco J, Lee NG. Granulomatosis with polyangiitis presenting as recurrent, multifocal orbital myositis. Orbit 2020;:1-3.Abstract
A 43-year-old woman was referred with a 10 month history of persistent pain in the left orbit. Two years prior, she experienced similar pain in the right orbit. Magnetic resonance imaging (MRI) at the time revealed an enlarged right medial rectus muscle. She was diagnosed with idiopathic orbital myositis and was successfully treated with oral corticosteroids. A year later, she developed symptoms in the left orbit with similar imaging findings. For ten months, she remained on high dose corticosteroids for presumed left medial rectus myositis before presenting to our service. Computed tomography (CT) imaging after corticosteroid taper revealed enlarged left medial rectus and left lateral rectus muscles. Orbital biopsy established a diagnosis of granulomatosis with polyangiitis (GPA), for which she was successfully treated with rituximab. This case underscores the importance of not only proceeding with biopsy in atypical cases of orbital myositis but to also taper steroids prior to biopsy.
Cohen LM, Liou VD, Cunnane ME, Yoon MK. Radiographic analysis of fatty infiltration of the extraocular muscles in thyroid eye disease. Orbit 2020;:1-6.Abstract
PURPOSE: Fatty infiltration of the extraocular muscles has been described radiographically in patients with thyroid eye disease (TED), yet it has not been studied on a large scale nor quantified. Our purpose was to define and characterize this entity in patients with TED. METHODS: An IRB-approved cross-sectional retrospective review of medical records identified patients with a clinical diagnosis of TED and at least one CT of the orbits. A 2:1 age and sex-matched control population consisted of patients without a history nor radiographic evidence of orbital disease or systemic thyroid abnormality. The presence of fatty infiltration in each extraocular rectus muscle was defined using Hounsfield units (HU). Laterality, muscles involved, and pattern of fatty infiltration were also evaluated. Student's t-tests, Chi-square, and Fisher's exact tests were used to compare TED and control groups. RESULTS: The study population consisted of 252 patients with TED and 504 age and sex-matched controls. Fatty infiltration was significantly more prevalent in TED patients (36/252, 14.3%) compared to controls (11/504, 2.2%) ( < .001). The mean density of fat infiltration was significantly lower in TED patients (-40.4 HU) than controls (-34.8 HU) ( = .048). In TED patients, the frequency of muscle involvement was inferior rectus (61.8%), lateral rectus (19.7%), superior rectus (11.8%) and medial rectus (6.6%), which was not significantly different than controls ( > .05). Most muscles (88.2%) in the TED group exhibited a heterogeneous pattern of infiltration, which did not differ from controls ( = .34). CONCLUSIONS: This study characterizes fatty infiltration of the extraocular muscles in patients with TED.
Singer MC, Marchal F, Angelos P, Bernet V, Boucai L, Buchholzer S, Burkey B, Eisele D, Erkul E, Faure F, Freitag SK, Gillespie MB, Harrell RM, Hartl D, Haymart M, Leffert J, Mandel S, Miller BS, Morris J, Pearce EN, Rahmati R, Ryan WR, Schaitkin B, Schlumberger M, Stack BC, Van Nostrand D, Wong KK, Randolph G. Salivary and lacrimal dysfunction after radioactive iodine for differentiated thyroid cancer: American Head and Neck Society Endocrine Surgery Section and Salivary Gland Section joint multidisciplinary clinical consensus statement of otolaryngology, ophth. Head Neck 2020;Abstract
BACKGROUND: Postoperative radioactive iodine (RAI) administration is widely utilized in patients with differentiated thyroid cancer. While beneficial in select patients, it is critical to recognize the potential negative sequelae of this treatment. The prevention, diagnosis, and management of the salivary and lacrimal complications of RAI exposure are addressed in this consensus statement. METHODS: A multidisciplinary panel of experts was convened under the auspices of the American Head and Neck Society Endocrine Surgery and Salivary Gland Sections. Following a comprehensive literature review to assess the current best evidence, this group developed six relevant consensus recommendations. RESULTS: Consensus recommendations on RAI were made in the areas of patient assessment, optimal utilization, complication prevention, and complication management. CONCLUSION: Salivary and lacrimal complications secondary to RAI exposure are common and need to be weighed when considering its use. The recommendations included in this statement provide direction for approaches to minimize and manage these complications.
Freitag SK, Aakalu VK, Tao JP, Wladis EJ, Foster JA, Sobel RK, Yen MT. Ophthalmic Technology Assessment - Sentinel Lymph Node Biopsy for Eyelid and Conjunctival Malignancy: A report by the American Academy of Ophthalmology. Ophthalmology 2020;Abstract
PURPOSE: To determine the efficacy and safety of sentinel lymph node biopsy (SLNB) in the management of eyelid and conjunctival malignancy. METHODS: A literature search was performed in August 2019 and January 2020 for articles published in English in the PubMed and Cochrane Library databases. This search yielded 151 articles that were reviewed for relevancy, of which 27 were deemed to have met the inclusion criteria for this assessment. The data from these articles were abstracted and the articles were rated for strength of evidence by the panel methodologist. RESULTS: All 27 studies were rated level III, and a total of 197 SLNBs were reported. Diagnoses included conjunctival and eyelid cutaneous melanoma (85 and 42 patients, respectively), sebaceous gland carcinoma (35), squamous cell carcinoma (26), Merkel cell carcinoma (6), pigmented epithelioid melanocytoid tumor (1), mucoepidermoid carcinoma (1), and signet ring carcinoma (1). Tracer was found in regional lymph nodes in 100% of patients in 21 of 27 articles and in 191 of 197 patients overall. The number of lymph nodes removed ranged from 1 to 16, with the majority ranging from 1 to 5. Tumor-positive lymph nodes were found in 33 of 197 (16.8%) patients, prompting recommendations for adjuvant treatments. Survival data were reported for 16 of these patients, with follow-up periods ranging from 3 to 36 (average 12.7) months. Fourteen of 16 patients received adjuvant treatments. Nine were alive and well, 1 was alive with metastases, and 6 died from metastatic disease (including 2 patients who refused additional treatment). False-negative SLNB was reported in 5 articles involving 9 of 197 (4.6%) procedures. Complications were documented in 7 of 27 articles and included transient facial nerve weakness, persistent blue-dye staining of the conjunctiva, neck hematoma, and suture abscess. CONCLUSIONS: Sentinel lymph node biopsy is a promising procedure in patients with eyelid and conjunctival malignancy, and it is useful in identifying sentinel lymph nodes. However, at present, there exists insufficient evidence that SLNB improves patient outcomes and survival. Recognition of microscopic metastatic disease may prove beneficial in staging and guiding adjuvant therapy.
Liou VD, Yoon MK. Advances in steroid sparing medical management of active thyroid eye disease. Semin Ophthalmol 2020;:1-8.Abstract
Thyroid eye disease (TED) is an autoimmune inflammatory disease of the orbit and the most common extrathyroidal manifestation of Graves disease. The release of pro-inflammatory cytokines is associated with inflammation of the ocular surface and lacrimal gland along with periorbital skin erythema and edema. Resultant tissue remodeling, fibrosis, and fat deposition can impart permanent physical changes to the ocular adnexa with effects on function and cosmesis. These changes occur in the active phase of disease, and it is during this time that steroids are often relied on to help alleviate symptoms. Due to the common and predictable side effects of long-term and high-dose steroid use, there has been a continuous effort to find alternative steroid-sparing medical management options for TED. This review highlights the various research studies that support the use of these medications.
Jakobiec FA, Hanbazazh M, Barrantes PC, Chodosh J. Adult Primary Capillary Hemangioma of the Sclera: A Previously Undescribed Entity With a Review of Epibulbar Vascular Lesions. Ophthalmic Plast Reconstr Surg 2020;36(4):327-333.Abstract
PURPOSE: The objective of this article is to document a unique case of a primary hemangioma and review epibulbar vascular tumors of the conjunctiva and episclera. METHODS: A case report with detailed histopathologic, histochemical, and immunohistochemical studies coupled with a comprehensive review of the relevant literature with a tabulation of previously reported epibulbar vascular lesions was performed. RESULTS: A vascular tumor developed in a 46-year-old woman over 2-3 months that histopathologically was located in the superficial third of the normally avascular sclera and was composed of capillary caliber vessels. CD31 and CD34 positivity established the vascular nature of the lesion. Despite its adult onset, the tumor was also glut-1 positive, a vascular characteristic of childhood capillary hemangiomas that will ultimately involute. Smooth muscle actin was positive in the endothelial cells and associated pericytes. An ectatic muscular vessel identified in the midst of the lesion was interpreted as an anomalous intrascleral branch of an epibulbar anterior ciliary artery, where it perforated the sclera in the vicinity of the insertion of an extraocular rectus muscle. It was deduced to be the source of the capillary proliferation. A literature review failed to identify any previously reported epibulbar vascular tumor that originated primarily in the sclera or secondarily infiltrated this ocular tunic. CONCLUSION: An adult primary capillary intrascleral neoplasm is described as the rarest of all epibulbar vascular tumors and in keeping with the exceptional status of the ocular endothelium was glut-1 positive. This lesion must be distinguished from an array of other common and esoteric epibulbar vascular conditions.
Tao JP, Aakalu VK, Wladis EJ, Sobel RK, Freitag SK, Foster JA, Yen MT. Bioengineered Acellular Dermal Matrix Spacer Grafts for Lower Eyelid Retraction Repair: A Report by the American Academy of Ophthalmology. Ophthalmology 2020;127(5):689-695.Abstract
PURPOSE: To review the literature on the efficacy and safety of bioengineered acellular dermal matrix (BADM) grafts for lower eyelid retraction repair. METHODS: A literature search was conducted in the PubMed database initially in January 2018 and updated in July 2019 to identify all studies in the English language literature on the use of BADM grafts in eyelid reconstruction. The searches yielded 193 citations, and 15 of the 34 articles selected for full review met all inclusion criteria for this assessment. A panel methodologist then assigned a level of evidence rating for each study. Two of the 15 studies included were rated level II and 13 were rated level III. RESULTS: The definition of success varied, but lower eyelid position improvement using lower lid margin-to-pupillary reflex distance was the most common outcome measure. Other end points were the amount of lagophthalmos, cosmesis, exposure, reoperation, or complications, as well as prosthesis retention in anophthalmic socket cases. The surgeon-reported success rate of these outcomes ranged from 75% to 100%. Minor complications included cyst formation, infection, chemosis, pyogenic granuloma, and corneal abrasion. No serious complications such as blindness, anaphylactic reaction, or terminal disease transmission occurred. Of the 526 implants included for assessment in these disparate studies, 27 cases (5%) required reoperation. CONCLUSIONS: No level I evidence was available, and the existing level II and level III studies have variable primary end points, study design limitations, and only short-term follow-up data. The current literature suggests that BADM grafts represent an implantation option for lower eyelid retraction repair. Short-term results are favorable, and the materials used may fill an important gap in care for patients for whom no acceptable alternatives exist, but long-term safety and efficacy remain unknown.
