RESUMO
PURPOSE: This study aims to conduct a narrative review about the current role of vitreoretinal surgery in the management of infectious and non-infectious uveitis. METHODS: This review was performed based on a search of the PubMed database or on relevant published papers according to our current knowledge. RESULTS: A total of 91 articles were identified in the literature review. With the advance of microincision vitrectomy surgery (MIVS), pars plana vitrectomy (PPV) has gained increasing popularity in the management of infectious and non-infectious uveitis. For diagnostic purposes, larger amounts of sample can be obtained by MIVS than traditional vitreous aspiration using needles. For treatment purposes, PPV removes vitreous opacities, decreases inflammatory cytokines and mediators of inflammation, and tackles related complications, including hypotony, epiretinal membrane, macular holes, and retinal detachment. Achieving optimum control of inflammation prior to surgery is important for surgical interventions for non-emergent therapeutic indications and complications of uveitis. Peri-operative inflammation management is essential for decreasing the risk of surgical intervention. An overall complication rate of 42-54% was reported with cataract to be the leading cause of complications. CONCLUSION: Most reports affirm the role of PPV in the management of infectious and non-infectious uveitis, although the quality of data remains limited by a lack of applying standardized reporting outcomes, limitations in study design, and a paucity of prospective data.

The molecular basis of intraocular tuberculosis (TB) is not well understood. In this study, we investigated the role of two constituents of viable Mycobacterium tuberculosis - Early Secreted Antigenic Target-6 (ESAT-6), and mycobacterial RNA- in inflammasome activation in the retinal pigment epithelium (RPE), a key site of inflammation in intraocular TB. We found that ESAT-6 induced caspase-1 activation and inflammasome priming in mouse RPE cells, substantially more in wild-type than in Tlr2/3/4/7/9-/-, Myd88-/- or Nlrp3-/- RPE cells. Sub-retinal ESAT-6 injection resulted in greater RPE degeneration in wild-type than in Nlrp3-/- mice. In human ocular TB tissue sections, NLRP3 staining was noted in retina as well as RPE. Mycobacterial RNA, specifically its double stranded component, also induced caspase-1 activation, and the double stranded RNA was immunolocalized to human ocular TB sections. Our observations suggest that inflammasome activation in RPE by viable M. tuberculosis could potentially contribute to human intraocular TB.

PURPOSE: To evaluate the 2-year outcomes of uveitic macular edema. DESIGN: Longitudinal follow-up of a randomized cohort. PARTICIPANTS: At baseline, 148 eyes of 117 patients enrolled in the Multicenter Uveitis Steroid Treatment (MUST) Trial had macular edema, and 134 eyes of 108 patients completed 2-year follow-up. METHODS: Patients enrolled in the study were randomized to either systemic immunosuppression or intravitreal fluocinolone acetonide implant therapy. Macular edema was defined as thickening of the retina (center point thickness≥240 µm) on time-domain optical coherence tomography (OCT) of macula. MAIN OUTCOME MEASURES: Improvement in macular edema (≥20% reduction in central point thickness on OCT), resolution of macular edema (normalization of thickness on OCT), and best-corrected visual acuity (BCVA). RESULTS: Between randomization and 2-years' follow-up, 62% and 25% of eyes in the systemic and implant groups, respectively, received at least 1 supplemental regional corticosteroid injection. By 2-years' follow-up, macular edema improved in 71% of eyes and resolved in 60%. There were no differences between treatment groups in the proportion of eyes with macular edema improving (systemic therapy vs. implant, 65% vs. 77%; P=0.20) and resolving (52% vs. 68%; P=0.28), but eyes randomized to implant had more improvement in macular thickness (median decrease of 180 vs. 109 µm in the systemic therapy group; P=0.04). Eyes with baseline fluorescein angiographic leakage were more likely to improve than those without (76% vs. 58%; P=0.03). Overall, there was a mean 5-letter (1 line) improvement in BCVA at 2 years. Mean changes in BCVA from baseline at 2 years by macular edema response status were: resolution, +10 letters; improvement without resolution, +10 letters (P=0.92); little to no change, 6 letters (P=0.19); and worsening, -16 letters (worsening acuity; P=0.0003). CONCLUSIONS: About two thirds of eyes with uveitic macular edema were observed to experience improvement in the edema and visual acuity with implant or systemic treatment. Fluocinolone acetonide implant therapy was associated with a greater quantitative improvement in thickness. Fluorescein angiography leakage was associated with a greater likelihood of improvement in macular edema.

Purpose: To investigate the use of super-resolution imaging techniques to enable telepathology using low-cost commercial cameras. Design: Experimental study. Participants: A total of 139 ophthalmic pathology slides obtained from the Ophthalmic Pathology service at the University of California, Irvine. Methods: Denoising Diffusion Probabilistic Model (DDPM) was developed to predict super-resolution pathology slide images from low-resolution inputs. The model was pretrained using 150 000 images randomly sampled from the ImageNet dataset. Patch aggregation was used to generate large images with DDPM. The performance of DDPM was evaluated against that of generative adversarial networks (GANs) and Robust UNet, which were also trained on the same dataset. Main Outcome Measures: The performance of models trained to generate super-resolution output images from low-resolution input images can be evaluated by using the mean squared error (MSE) and Structural Similarity Index Measure (SSIM), as well as subjective grades provided by expert pathologist graders. Results: In total, our study included 110 training images, 9 validation images, and 20 testing images. The objective performance scores were averaged over patches generated from 20 test images. The DDPM-based approach with pretraining produced the best results, with an MSE score of 1.35e-5 and an SSIM score of 0.8987. A qualitative analysis of super-resolution images was conducted by expert 3 pathologists and 1 expert ophthalmic microscopist, and the average accuracy of identifying the correct ground truth images ranged from 25% to 70% (with an average accuracy of 46.5%) for widefield images and 25% to 60% (with an average accuracy of 38.25%) for individual patches. Conclusions: The DDPM-based approach with pretraining is assessed to be effective at super-resolution prediction for ophthalmic pathology slides both in terms of objective and subjective measures. The proposed methodology is expected to decrease the reliance on costly slide scanners for acquiring high-quality pathology slide images, while also streamlining clinical workflow and expanding the scope of ophthalmic telepathology.

RESUMO
Introduction: Uveitis and related intraocular inflammations are a major cause of blindness due to retinal damage caused by degeneration and loss of the photoreceptor cells. In mouse experimental autoimmune uveitis (EAU) previously we have shown mitochondrial oxidative stress with marked upregulation of αA crystallin in the inner segments of the photoreceptors. Furthermore, αA crystallin treatment prevented photoreceptor mitochondrial oxidative stress by suppressing innate and adaptive immunity in EAU. Methods: Since these immune processes are modulated by microRNAs, in this study we investigated (a) modulation of microRNAs during development of EAU by αA crystallin administration and (b) microRNA therapeutic intervention. Results: Few microRNAs were significantly upregulated in EAU mice with intravenous injection of αA crystallin and among these, computational bioinformatic analysis revealed that the upregulated microRNA 146a targets the innate and adaptive immune responses. In EAU, intravenous as well as intravitreal administration of this microRNA prevented inflammatory cell infiltration in uvea and retina and preserved photoreceptor cells. Discussion: This protective function suggests that microRNA146a can be a novel therapeutic agent in preventing retinal damage in uveitis.
RESUMO
Sarcoidosis is a multisystem granulomatous inflammation that affects multiple organ systems. The spectrum of extraocular and ocular involvement is wide and may precede systemic involvement. The diagnosis of ocular sarcoidosis relies on a combination of clinical findings, laboratory investigations, and radiographic findings. These include but are not limited to serum angiotensin-converting enzyme (ACE), lysozyme, plain-film radiographs of the chest, computed tomography (CT) scans of the chest, pulmonary function testing, bronchoalveolar lavage, and retinal imaging among others. In this review, we highlight current and evolving systemic investigations and approaches to ophthalmic imaging when considering the diagnosis of ocular sarcoidosis.

PURPOSE: To report a case of Aspergillus fumigatus endogenous endophthalmitis in an immunocompetent patient initially diagnosed as acute retinal necrosis. METHODS: Case report. PATIENT: A 67-year-old woman with a remote history of treated pulmonary tuberculosis and no ocular history presented to an outside retina specialist with a sudden onset of floaters and blurred vision in one eye. Examination and fluorescein angiography at the time revealed findings suspicious for acute retinal necrosis, and the patient was started on oral valganciclovir and an intravitreal injection of ganciclovir. Despite treatment, the patient's vision and pain worsened. After evaluation at the University of Southern California Roski Eye Institute, she was diagnosed with a likely fungal endogenous endophthalmitis based on ultrasound findings and underwent emergent vitrectomy. A chest x-ray demonstrated partial collapse of the right upper lobe with hilar enlargement. RESULTS: Aspergillus fumigatus was cultured from vitreous, blood, and bronchoalveolar lavage samples, suggesting that the patient's infection had a pulmonary origin, most likely from the right upper lobe that had healed from previous tuberculosis infection. DISCUSSION: To the best of our knowledge, this is the first reported case of Aspergillus endogenous endophthalmitis in an immunocompetent patient secondary to pulmonary changes that occurred from previously treated tuberculosis.

This article describes two cases of delayed-onset Cutibacterium acnes (C acnes) endophthalmitis 1 month after cataract surgery manifesting with unusual epiretinal deposits. Both patients were referred for persistent inflammation after cataract surgery. After failing to respond to a vitreous tap with injection of antibiotics, the patients underwent pars plana vitrectomy and in one of the cases partial posterior capsulectomy for a posterior capsular plaque. Intraoperatively, both cases were found to have unusual multifocal epiretinal deposits. The clinical presentations described here represent a highly unique manifestation of C acnes endophthalmitis distinct from the classic anterior segment findings.

PURPOSE: Posttranslational modification of proteins plays an important role in cellular functions and is a key event in signal transduction pathways leading to oxidative stress and DNA damage. In this study, we used matrix-assisted laser desorption/ionization- time of flight (MALDI-TOF) to investigate the posttranslational modifications of the differentially expressed proteins in the retinal mitochondria during early experimental autoimmune uveitis (EAU). METHODS: EAU was induced in 18 B10RIII mice with 25 µg of inter-photoreceptor retinoid-binding protein (IRBP) emulsified with complete Freund's adjuvant (CFA); 18 mice treated with CFA without IRBP served as controls. Retinas were removed from the experimental and control groups on day 7 post immunization; mitochondrial fractions were extracted and subjected to 2 dimentional-difference in gel electrophoresis (2D-DIGE); and the protein spots indicating differential expression were subjected to MALDI-TOF for protein identification and indication of any posttranslational modifications. RESULTS: Of the 13 proteins found to be differentially expressed by 2D-DIGE (including upregulated aconitase, mitochondrial heat shock protein (mtHsp) 70, lamin-1, syntaxin-binding protein, αA crystallin, ßB2 crystallin, along with downregulated guanine nucleotide-binding protein and ATP synthase) nine were found to undergo posttranslational modification. Oxidation was a common modification found to occur on aconitase, mtHsp 70, ATP synthase, lamin-1, ßB2-crystallin, guanine nucleotide-binding protein, and manganese superoxide dismutase (MnSOD). In addition, aconitase hydratase, mtHsp 70, guanine nucleotide-binding protein, ATP synthase, syntaxin-binding protein, ßB2-crystallin, and lamin-1 were also modified by carbamidomethylation. αA-crystallin had a pyro-glu modification. CONCLUSIONS: Several proteins present in the retinal mitochondria are posttranslationally modified during early EAU, indicating the presence of oxidative stress and mitochondrial DNA damage. The most common modifications are oxidation and carbamidomethylation. A better understanding of the proteins susceptible to posttranslational modifications in the mitochondria at the early stage of the disease may serve to advance therapeutic interventions to attenuate disease progression.

OBJECTIVE: To analyze the clinical profiles, histopathologic features, and Mycobacterium tuberculosis polymerase chain reaction testing in patients with ocular tuberculosis. DESIGN: Retrospective case series. PARTICIPANTS: Forty-two patients. METHODS: This retrospective study was approved by the Armed Forces Institute of Pathology (AFIP) Institutional Review Board. The AFIP data banks were screened for cases with diagnosis of ocular tuberculosis using key words such as mycobacterium; tuberculosis; and acid-fast bacilli. Files and slides stained with hematoxylin-eosin and acid-fast staining were reviewed by the Division of Ocular Pathology and by the Infectious Diseases and Parasitic Diseases Pathology Branches. When available; blocks and unstained slides were sent to the Doheny Eye Institute; Los Angeles; California; for quantitative polymerase chain reaction (qPCR) analysis to detect Mycobacterium tuberculosis-specific DNA. MAIN OUTCOME MEASURES: Tuberculin skin test (TST) results, as well as the chest radiograph results, were recorded. When acid-fast bacilli were identified in tissue, their locations-ocular or extraocular sites-were recorded. Emphasis was placed on lymph node involvement and any systemic diseases. RESULTS: In the histopathologic specimens, microscopy revealed a paucity of organisms, and often there were only 1 or 2 organisms associated with or near a giant cell or near an area of necrosis. The qPCR analysis was performed on 6 biopsy specimens. These specimens showed necrotizing granulomatous inflammation from 6 different patients; 3 had positive qPCR results. In 2 of the 3 cases with positive qPCR results, acid-fast bacilli were not found in the tissue sections. In 17 patients, TST results were available; 10 had positive results (60%) and 7 had negative results (40%). Fourteen chest radiograph results were submitted, and 8 (57%) of 14 patients had normal chest films. CONCLUSIONS: This study suggests that in dealing with those populations at increased risk of tuberculosis (e.g., immigrants from endemic areas and human immunodeficiency virus-infected patients) or patients receiving biologic therapy, the ophthalmologist should endeavor to entertain this diagnosis and to rely on the support of infectious disease specialists and pulmonologists to help solidify the diagnosis, because the current methods for the diagnosis have limited sensitivity.

Purpose: To identify the temporal relationship and clinical characteristics of epiretinal membrane (ERM) and macular edema (ME) formation in uveitic eyes.Methods: A total of 269 subjects (444 uveitic eyes) met study inclusion criteria. Comprehensive ophthalmic examination, spectral domain-optical coherence tomography (SD-OCT), and clinical testing were carried out.Results: Of the 444 uveitic eyes, 229 eyes (51.6%) developed an ERM, whereas 87 eyes (19.1%) developed ME. The odds ratios (ORs) of systemic disease causing uveitis and resulting in ERM and ME were significantly higher in posterior uveitis (OR 6.56, 95% CI 2.98-14.46; p < .0001) and panuveitis (OR 10.09, 95% CI 4.05-25.15; p < .0001). Temporal analysis revealed that an ERM was noted concurrently or prior to ME development in 93.8% of eyes.Conclusions: ERM and ME are primarily observed in posterior uveitis and panuveitis associated with systemic diseases. The temporal relationship highlights the importance of characterization of ERM as it relates to the development of uveitic ME.

PURPOSE: The aim of this study was to assess possible correlation between the visual field and electroretinogram (ERG) parameters in birdshot chorioretinopathy (BCR). DESIGN: Retrospective cross-sectional study. METHODS: This single-center study included 21 eyes of 11 patients with BCR with prior ERG and Goldmann kinetic perimetry. Generalized estimating equation was used for statistical analysis, and isopters V4e and I4e were modeled as separate outcomes with each parameter of ERG as the main independent variable. The main outcome measure was presence or absence of correlation between the Goldmann isopters and ERG parameters including the amplitudes and implicit times of dark adapted (DA) and light adapted (LA) a-waves and b-waves (DA 0.01, DA 3.0, DA 10.0, and LA 3.0) and LA 30âHz. RESULTS: There was a strong positive correlation between the size of isopter V4e and all the scotopic and photopic standard ERG amplitudes [Pâ<â0.0001 for all, except LA 3.0 a-wave (Pâ=â0.0019) and LA 30âHz (Pâ=â0.0026)]. For the implicit times, only DA 3.0 a-wave (Pâ=â0.007) and LA 30âHz (Pâ<â0.0001) showed significant negative correlations. There were no correlations between the size of isopter I4e and any ERG amplitudes; however, 3 implicit times showed some negative correlation: DA 3.0 a-wave (Pâ<â0.0001), DA 10.0 b-wave (Pâ=â0.0251), and LA 3.0 b-wave (Pâ<â0.0001). CONCLUSIONS: In this study, the largest isopter of Glodmann visual field showed a strong positive correlation with all standard ERG amplitudes in BCR. This novel finding underscores the role of ERG as an objective visual function test in monitoring the disease activity.

AIMS: To establish expert recommendations for the management of ocular sarcoidosis (OS). METHODS: A question-based survey on the management of OS was circulated to international uveitis experts (members of the International Uveitis Study Group and the International Ocular Inflammation Society) electronically. Subsequently, a consensus workshop was conducted at the 7th International Workshop on Ocular Sarcoidosis (IWOS) in June 2019 in Sapporo, Japan as part of the Global Ocular Inflammation Workshops. Statements on the management of OS that were supported by a two-thirds majority of 10 international panel members of the workshop, after discussion and voting, were taken as consensus agreement. RESULTS: A total of 98 participants from 29 countries responded to the questionnaire survey. The subsequent consensus workshop established recommendations for the management of OS in five sections. The first section concerned evaluation and monitoring of inflammation. The second, third and fourth sections described ocular manifestations that were indications for treatment, and the management of anterior uveitis, intermediate uveitis and posterior uveitis. In the fifth section, the use of systemic corticosteroids and systemic immunosuppressive drugs were detailed. CONCLUSIONS: Recommendations for management of OS were formulated through an IWOS consensus workshop.

OBJECTIVE: To report the diagnostic, clinical, and histopathologic features of a patient with coccidioidomycosis endophthalmitis without concomitant systemic involvement diagnosed by vitreous biopsy. DESIGN: Interventional case report. PARTICIPANTS: One patient. INTERVENTION: Diagnostic pars plana vitrectomy, systemic and intravitreal antifungal treatment, and enucleation. MAIN OUTCOME MEASURES: Diagnostic, clinical, and histopathologic features of chronic coccidioidomycosis endophthalmitis. RESULTS: A 64-year-old white man from Southern California presented with chronic intraocular inflammation in the right eye that had lasted 18 months. He had been unsuccessfully treated with topical and subtenon steroids. At presentation, best-corrected visual acuity was 20/400 in the right eye and 20/20 in the left eye. Ophthalmoscopy of the right eye revealed significant vitritis and multiple yellowish chorioretinal lesions. Evaluation by an internist showed no underlying inflammatory, infectious, or neoplastic systemic illnesses. A vitreous biopsy followed by histopathologic examination showed the presence of multiple Coccidioides sp. microorganisms. The patient was then treated with intravitreal amphotericin B and oral fluconazole. Best-corrected visual acuity initially improved to 20/80, but inflammation progressed and did not respond to 2 subsequent injections of antifungals, 2 additional pars plana vitrectomies, and oral fluconazole. The eye eventually became blind and painful and was enucleated. Histopathologic examination disclosed intraocular granulomas displaying multiple Coccidioides sp. microorganisms. CONCLUSIONS: Coccidioides sp. endophthalmitis may present with no concomitant systemic involvement. Histopathologic examination of the vitreous is helpful in the diagnosis. A high index of suspicion is important, especially in areas where the incidence of coccidioidomycosis is rising.

PURPOSE: To determine the frequency of occurrence of limited clinical features which distinguish patients with Vogt-Koyanagi-Harada (VKH) disease from those with non-VKH uveitis. DESIGN: Comparative case series. PARTICIPANTS: We included 1147 patients. METHODS: All patients with bilateral ocular inflammatory disease presenting to any of 10 uveitis centers in the 3-month period between January 1 and March 31, 2006 (inclusive), were asked to participate. The clinical and historical features of disease were obtained from the participants via direct interview and chart review. Patients were stratified based on whether they were diagnosed with VKH disease or non-VKH uveitis for statistical analysis. MAIN OUTCOME MEASURES: Presence or absence of various clinical features in the 2 populations. RESULTS: Of 1147 patients, 180 were diagnosed with VKH disease and 967 with non-VKH uveitis. Hispanics and Asians were more likely to be diagnosed with VKH than non-VKH disease compared with other ethnicities. In acute disease, the finding of exudative retinal detachment was most likely to be found in VKH disease with a positive predictive value (PPV) of 100 and negative predictive value (NPV) of 88.4, whereas in chronic disease, sunset glow fundus was most likely to be found, with a PPV of 94.5 and NPV of 89.2. CONCLUSIONS: Numerous clinical findings have been described in the past as important in the diagnosis of VKH. The current study reveals that of these, 2 are highly specific to this entity in an ethnically and geographically diverse group of patients with nontraumatic bilateral uveitis. These clinical findings are exudative retinal detachment during acute disease and sunset glow fundus during the chronic phase of the disease.

BACKGROUND: The indications for enucleation have changed significantly over the past 60 years. We conducted a clinicopathologic study of enucleated globes to determine how and why the indications for enucleation have changed over time. METHODS: This retrospective review examined the pathology reports for 3,264 enucleated globes submitted to the Doheny Eye Institute between 1950 and 2006. Three years per decade were examined to generate a representative pool of specimens for each decade. Although the data for the 2000s were only available up to 2006, the data for this decade are drawn from 3 sample years as are all other decades. Pathology reports were reviewed for demographic information (age, sex, and ethnicity), clinical history prior to enucleation, and pathologic findings and diagnoses. Specimens were grouped according to the reason for enucleation into the following categories: atrophic/phthisis bulbi, congenital, glaucoma, infection, longstanding retinal detachment, trauma, tumor, uveitis, and other. RESULTS: During the study period, there were 3,264 enucleated globes. Overall, the total number of enucleations decreased over time from a peak of 1,014 in the 1960s to 275 in the 2000s. Glaucoma was the most common reason for enucleation during the 1950s (23%, 127 globes) and 1960s (31%, 315 globes). However, glaucoma steadily decreased over the following decades, and was responsible for only 8% (23 globes) of enucleations in the 2000s. Neovascular glaucoma (including glaucoma secondary to retinal vein occlusion and diabetic neovascularization) accounted for 21% (27 globes) of enucleations in the 1950s. By the 2000s, this number was 57% (13 globes). Trauma-related glaucoma accounted for 34% (43 globes) of all enucleations due to glaucoma in the 1950s, and 0% (0 globes) in the 2000s. Enucleation of globes with intraocular neoplasms accounted for 14% (79 globes) of total enucleations in the 1950s, 33% (120 globes) in the 1990s, and 51% (141 globes) in the 2000s. Uveal melanoma was the main intraocular neoplasm in the 1950s (77%, 60 globes), and retinoblastoma was the primary tumor in the enucleated globes of the 2000s (69%, 97 globes). CONCLUSIONS: Improved medical and surgical treatment of conditions that lead to end-stage eye disease have led to a decrease in total enucleated globes. This is particularly evident for glaucoma. Changing demographics in Los Angeles and referral patterns are most likely responsible for the increase in retinoblastoma. The absolute number of enucleations secondary to neoplasms has not decreased over time, despite an increase in globe-conserving treatments such as chemotherapy and radioactive plaques.

PURPOSE: The purpose of this study was to determine whether fundus autofluorescence (FAF) and spectral domain-optical coherence tomography (SD-OCT) imaging allow better assessment of retinal pigment epithelium and the outer retina in subjects with chronic Vogt-Koyanagi-Harada disease compared with examination and angiography alone. METHODS: A cross-sectional analysis of a series of seven consecutive patients with chronic Vogt-Koyanagi-Harada disease undergoing FAF and SD-OCT was conducted. Chronic disease was defined as duration of intraocular inflammation >3 months. Color fundus photographs were correlated to FAF and SD-OCT images. The images were later correlated to fluorescein angiography and indocyanine green angiography. RESULTS: All patients had sunset glow fundus, which resulted in no apparent corresponding abnormality on FAF or SD-OCT. Lesions with decreased autofluorescence signal were observed in 11 eyes (85%), being associated with loss of the retinal pigment epithelium and involvement of the outer retina on SD-OCT. In 5 eyes (38%), some of these lesions were very subtle on clinical examination but easily detected by FAF. Lesions with increased autofluorescence signal were seen in 8 eyes (61.5%), showing variable involvement of the outer retina on SD-OCT and corresponding clinically to areas of retinal pigment epithelium proliferation and cystoid macular edema. CONCLUSION: Combined use of FAF and SD-OCT imaging allowed noninvasive delineation of retinal pigment epithelium/outer retina changes in patients with chronic Vogt-Koyanagi-Harada disease, which were consistent with previous histopathologic reports. Some of these changes were not apparent on clinical examination.

We present an interventional case report of exfoliating goblet cell hyperplasia mimicking pterygium. A 44-year-old male with bilateral lesions of the nasal bulbar conjunctiva extending over the cornea, consistent with pterygia, underwent surgical excision of the lesion in his left eye. Histopathologic examination revealed an exophytic lesion made up of proliferated goblet cells with benign cytologic features. Some of the goblet cells were atrophic and seemed to be desquamating from the lesion surface. Cytologic examination of a tear specimen collected from the right eye revealed the presence of exfoliated goblet cells admixed with mucin material. The lesion had not recurred three months after surgery. Exfoliating goblet cell hyperplasia, a condition not previously reported on the ocular surface, may mimic pterygium. Histopathologic examination is required to establish the diagnosis.
