BACKGROUND: The objective of this study is to describe a system for color photograph evaluation in uveitis and report baseline morphologic findings for the Multicenter Uveitis Steroid Treatment (MUST) Trial. Four-hundred seventy-nine eyes of 255 subjects with intermediate, posterior, and panuveitis had stereoscopic color fundus photographs obtained by certified photographers and evaluated by certified graders using standardized procedures to evaluate morphologic characteristics of uveitis. The posterior pole was evaluated for macular edema, vitreoretinal interface abnormalities, and macular pigment disturbance/atrophy; the optic disk was assessed for edema, pallor, or glaucomatous changes. The presence of neovascularization, vascular occlusion, vascular sheathing, and tractional …

Wills Eye Hospital Papers

Purpose: Intraocular medulloepithelioma (IM), the second most common primary neuroepithelial tumor of the eye, can lead to blindness in the affected eye and in rare cases, is deadly. Intraocular medulloepithelioma lacks targetable biomarkers for potential pharmacologic therapy. The purpose of this study was to identify actionable, tumor-specific proteins for potential diagnostic or therapeutic strategies. We hypothesize that the tumor-specific epigenetic enzyme EZH2 is selectively expressed in IM.

Methods: We conducted a retrospective case series study of five IM from five eyes of four children and one adult. Hematoxylin and eosin (H&E) stains of sections from formalin-fixed, paraffin-embedded blocks of IM …

Retinal Ganglion Cell And Inner Plexiform Layer Loss Correlate With Visual Acuity Loss In Lhon: A Longitudinal, Segmentation Oct Analysis., Stephen J Moster, Mark L Moster, Molly Scannell Bryan, Robert C Sergott

Wills Eye Hospital Papers

PURPOSE: Describe changes in the retina as vision loss progresses in Leber's Hereditary Optic Neuropathy (LHON) using spectral-domain optical coherence tomography (SD-OCT) autosegmentation, and determine if relationship exists between retinal changes and vision loss.

METHODS: From patient records we identified nine LHON patients who underwent periodic neuro-ophthalmologic examinations and high-resolution SD-OCT as part of their care. We describe the impact of LHON progression on each retinal layer, and the relationship between these structural changes and visual acuity using generalized estimating equations and nonparametric tests.

RESULTS: The thickness of the ganglion cell layer (GCL) and inner plexiform layer (IPL) decreased immediately …

Purpose: To determine the sensitivity of the combination of optical coherence tomography angiography (OCTA) and structural optical coherence tomography (OCT) for detecting type 1 neovascularization (NV) and to determine significant factors that preclude visualization of type 1 NV using OCTA.

Methods: Multicenter, retrospective cohort study of 115 eyes from 100 patients with type 1 NV. A retrospective review of fluorescein (FA), OCT, and OCTA imaging was performed on a consecutive series of eyes with type 1 NV from five institutions. Unmasked graders utilized FA and structural OCT data to determine the diagnosis of type 1 NV. Masked graders evaluated FA …


Illness Cognitions And Coping Self-Efficacy In Depression Among Persons With Low Vision., Bonnie A Sturrock, Jing Xie, Edith E Holloway, Mark Hegel, Robin J. Casten, David Mellor, Eva Fenwick, Gwyneth Rees Jun 2016

Illness Cognitions And Coping Self-Efficacy In Depression Among Persons With Low Vision., Bonnie A Sturrock, Jing Xie, Edith E Holloway, Mark Hegel, Robin J. Casten, David Mellor, Eva Fenwick, Gwyneth Rees

Department of Psychiatry and Human Behavior Faculty Papers

PURPOSE: To investigate the mediating role of coping self-efficacy (CSE) between two types of illness cognitions (i.e., acceptance and helplessness) and depressive symptoms in persons with low vision.

METHODS: This was a single-group, cross-sectional study. Patients with visual acuity < 6/12 in the better eye and at least minimal depressive symptoms (≥5 on the Patient Health Questionnaire-9 [PHQ-9]) were recruited from vision rehabilitation services and participated in telephone-administered structured interviews at one time point. Measures were the PHQ-9, CSE Scale, and Illness Cognition Questionnaire. Structural equation modeling (SEM) devised the causal flow of illness cognitions and their observed indirect effects on depressive symptoms via the CSE mediators: problem focused, emotion focused, and social support.

RESULTS: The study comprised 163 patients (mean age 62 years; 61% female), most with age-related macular degeneration (26%) and moderate vision impairment (44%, <6/18-6/60). Structural equation modeling indices indicated a perfect fit (χ2 < 0.001, P = 1.00), accounting for 55% of the variance in depressive symptoms. Lower levels of acceptance and higher levels of helplessness illness cognitions were associated with lower self-efficacy in problem-focused coping (β = 0.38, P < 0.001, β = -0.28, P < 0.01, respectively), which in turn was associated with greater depressive symptom severity (β = -0.54, P < 0.001).

CONCLUSIONS: Lack of acceptance and greater helplessness relating to low vision led to a lack of perceived capability to engage in problem-focused coping, which in turn promoted depressive symptoms. Third-wave cognitive-behavioral treatments that focus on acceptance may be …


Radiotherapy For Iris Metastasis From Esophageal Carcinoma: A Series Of Three Cases., Chandana Das, Carol L Shields Jun 2016

Radiotherapy For Iris Metastasis From Esophageal Carcinoma: A Series Of Three Cases., Chandana Das, Carol L Shields

Wills Eye Hospital Papers

BACKGROUND: Description of three cases of metastatic esophageal carcinoma to the iris and focus on management strategies.

METHODS: A 48-year-old man (Case 1) with previously treated stage IV esophageal carcinoma presented with blurred vision in the left eye (OS) for 3 weeks. Initial fine needle aspiration biopsy (FNAB) was negative for malignant cells, so incisional biopsy was performed and confirmed metastatic carcinoma. A 53-year-old man (Case 2) with previously treated stage III esophageal cancer experienced 2 months of pain and 1 month of blurred vision OS. Documented tumor growth suggested esophageal carcinoma metastasis. A 65-year-old man (Case 3) with previously …

Wills Eye Hospital Papers

BACKGROUND: Uveitis is a term used to describe a heterogeneous group of intraocular inflammatory diseases of the anterior, intermediate, and posterior uveal tract (iris, ciliary body, choroid). Uveitis is the fifth most common cause of vision loss in high-income countries, accounting for 5% to 20% of legal blindness, with the highest incidence of disease in the working-age population.Corticosteroids are the mainstay of acute treatment for all anatomical subtypes of non-infectious uveitis and can be administered orally, topically with drops or ointments, by periocular (around the eye) or intravitreal (inside the eye) injection, or by surgical implantation.

OBJECTIVES: To determine the …


Consecutive Bilateral Decompression Retinopathy After Mitomycin C Trabeculectomy: A Case Report., Ana Raquel Marcos Figueiredo, Isabel Coutinho Sampaio, Maria João Fernandes Dos Santos Menéres, George L. Spaeth Feb 2016

Consecutive Bilateral Decompression Retinopathy After Mitomycin C Trabeculectomy: A Case Report., Ana Raquel Marcos Figueiredo, Isabel Coutinho Sampaio, Maria João Fernandes Dos Santos Menéres, George L. Spaeth

Wills Eye Hospital Papers

BACKGROUND: After a successful trabeculectomy, a sudden intraocular pressure decrease may alter the intracranial to intraocular pressure ratio and cause decompression retinopathy. Frequent Valsalva maneuvers may also play a role in its pathogenesis. This condition may manifest as multiple retinal hemorrhages, edema of the optic disc, macular edema, or a sudden decrease in visual acuity postoperatively. Outcomes for patients are usually good, with spontaneous resolution occurring within a matter of weeks. It has been rarely reported in the literature as a bilateral condition.

CASE PRESENTATION: We present a case of consecutive bilateral decompression retinopathy in a 54-year-old severely obese Caucasian …

Organophosphates have rarely been reported to cause various ocular sequelae including retinal degeneration. Retinal manifestations have been rarely reported and poorly characterized. We describe a case of a 76-year-old man with vision loss beginning in his 20s due to acute on chronic exposure to dimethoate, an organophosphate. He presented with bilateral geographic macular atrophy and midperipheral pigmentary clumping which we characterized by dilated fundoscopic examination, optical coherence tomography, and fundus autofluorescence.
