Vitamin A And Fish Oils For Preventing The Progression Of Retinitis Pigmentosa., Stephen G. Schwartz, Xue Wang, Pamela Chavis, Ajay E. Kuriyan, Samuel A. Abariga

Wills Eye Hospital Papers

BACKGROUND: Retinitis pigmentosa (RP) comprises a group of hereditary eye diseases characterized by progressive degeneration of retinal photoreceptors. It results in severe visual loss that may lead to blindness. Symptoms may become manifest during childhood or adulthood which include poor night vision (nyctalopia) and constriction of peripheral vision (visual field loss). Visual field loss is progressive and affects central vision later in the disease course. The worldwide prevalence of RP is approximately 1 in 4000, with 100,000 individuals affected in the USA. At this time, there is no proven therapy for RP.

OBJECTIVES: The objective of this review was to …

Wills Eye Hospital Papers

Importance: Primary diffuse large B-cell lymphoma (DLBCL) of the ocular region is rare, and the utility of surgery and radiation therapy remains unresolved.

Objective: To explore the clinical characteristics and determine factors associated with overall survival in primary vitreoretinal lymphoma (PVRL) and ocular adnexal (OA)-uveal DLBCL.

Design, Setting, and Participants: This retrospective analysis included 396 patients with ophthalmic DLBCL from January 1, 1973, through December 31, 2014, using the Surveillance, Epidemiology, and End Results database. The median follow-up was 39.0 months (interquartile range, 5.1-72.9 months). All patients diagnosed with primary DLBCL of the eye or retina (PVRL) or the eyelid, …

Wills Eye Hospital Papers

PURPOSE: To evaluate the response to intravitreal triamcinolone acetonide for macular edema persisting or recurring despite multiple intravitreal bevacizumab (IVB) treatments for central retinal vein occlusion (CRVO).

METHODS: Retrospective interventional case series of 21 eyes with CRVO from 21 patients who were diagnosed with persistent or recurrent macular edema secondary to CRVO and treated with 0.1mL (4mg) intravitreal triamcinolone acetonide (IVTA) after initial treatment with 3 or more IVB injections. Anatomic and visual responses were the study primary outcomes.

RESULTS: Mean logarithm of the minimum angle of resolution visual acuity was 1.19 (20/316) immediately before IVTA injection, and improved to …

High-Speed Optical Coherence Tomography As A Reliable Adjuvant Tool To Grade Ocular Anterior Chamber Inflammation., Ann O. Igbre, Mario C. Rico, Sunir Garg

Wills Eye Hospital Papers

PURPOSE: To evaluate the high-speed anterior segment optical coherence tomography (AS-OCT) grading of the AS inflammation in patients with ocular inflammation.

METHODS: A retrospective consecutive case series study. Patients with clinically visible AS inflammation in at least one eye underwent AS-OCT (Visante; Zeiss Meditec) with three to eight line scans per eye, performed by a trained masked examiner. The images were reviewed for hyperreflective spots, noise, and artifact, and these were correlated to clinical examination.

RESULTS: Seventy-eight eyes of 41 patients were imaged. Forty-seven eyes had anterior chamber cells on clinical examination, and 68 had hyperreflective spots visible on AS-OCT. …

Treatment Of Steroid-Induced Elevated Intraocular Pressure With Anecortave Acetate: A Randomized Clinical Trial., Ingeborg Stalmans, David G. Callanan, Monte S. Dirks, Marlene R. Moster, Alan L. Robin, Joachim Van Calster, Sally A. Scheib, Jaime E. Dickerson, Theresa A. Landry, Michael V. W. Bergamini

Wills Eye Hospital Papers

PURPOSE: The present study is the first randomized clinical trial designed to evaluate the intraocular pressure (IOP)-lowering effect of anecortave acetate (AA) administered at 3 doses (3, 15, or 30 mg) as an anterior juxtascleral depot (AJD) in patients experiencing elevated IOP due to corticosteroid therapy.

METHODS: This was a double-masked, randomized, placebo-controlled, multicenter, parallel group trial. Eligible patients had an IOP of at least 24 mmHg and an IOP increase of at least 10 mmHg relative to their IOP before treatment with steroids. A target IOP was established for each patient at baseline. Patients were randomized to 1 of …

Absence Of Altered Expression Of Optineurin In Primary Open Angle Glaucoma Patients., Khaled K Abu-Amero, Taif Anwar Azad, George L Spaeth, Jonathan Myers, L Jay Katz, Marlene Moster, Thomas M Bosley

Wills Eye Hospital Papers

PURPOSE: To investigate the expression level of the optineurin gene (OPTN) in the blood of primary open angle glaucoma (POAG) patients to determine if altered expression is playing a role in primary open angle glaucoma systemically.

METHODS: Patients (n=47) were eligible for inclusion if they met standard clinical criteria for POAG, including age greater than 40 years, intraocular pressure ≥21 mmHg in at least one eye before treatment, normal-appearing anterior chamber angles bilaterally on gonioscopy, and optic nerve injury characteristic of POAG. Control subjects (n=27) were recruited who were free from glaucoma by examination. DNA from patient was sequenced to …

Unaltered Myocilin Expression In The Blood Of Primary Open Angle Glaucoma Patients., Khaled K Abu-Amero, Taif Anwar Azad, George L Spaeth, Jonathan Myers, L Jay Katz, Marlene Moster, Thomas M Bosley

Wills Eye Hospital Papers

PURPOSE: To investigate the expression of the myocilin gene (MYOC) in the blood of primary open angle glaucoma (POAG) patients to determine if altered systemic expression is playing a role.

METHODS: Patients (n=47) were eligible for inclusion if they met standard clinical criteria for POAG. Control subjects (n=27) were recruited who were free from glaucoma by examination. RNA was extracted from leukocytes of patients and controls and converted to cDNA by reverse transcriptase enzyme, and quantitative PCR was used to assess expression levels of MYOC and the house keeping gene β-globulin (HBB). The ratio of MYOC expression to HBB expression …

The Assessment Of Disability Related To Vision Performance-Based Measure In Diabetic Retinopathy., Kevin J. Warrian, Luciano L. Lorenzana, Dara Lankaranian, Jyoti Dugar, Sheryl S. Wizov, George L. Spaeth

Wills Eye Hospital Papers

PURPOSE: To validate a third-generation performance-based measure of visual function titled "Assessment of Disability Related to Vision" (ADREV) in a study population of patients with diabetic retinopathy.

DESIGN: Prospective, cross-sectional study.

METHODS: Patients with nonproliferative or proliferative diabetic retinopathy, free from ocular comorbidity, were recruited from a single institute and completed the ADREV, the 25-Item National Eye Institute Visual Functioning Questionnaire (VFQ-25), and a clinical ophthalmic examination. Correlation, regression, and bootstrap analysis were conducted to determine the relationship between ADREV scoring and each of the study's clinical and self-report measures of visual ability, while controlling for potential confounders.

RESULTS: Ninety-one …

High-Resolution Analysis Of Dna Copy Number Alterations In Patients With Primary Open-Angle Glaucoma., Khaled K Abu-Amero, Ali Hellani, Patrick Bender, George L. Spaeth, Jonathan Myers, L Jay Katz, Marlene Moster, Thomas M Bosley

Wills Eye Hospital Papers

PURPOSE: To determine whether patients with isolated primary open-angle glaucoma (POAG) have evidence of chromosomal copy number alterations.

METHODS: Twenty-seven Caucasian and African-American POAG patients and 12 ethnically matched controls were carefully screened for possible glaucoma and tested for chromosomal copy number alterations using high resolution array comparative genomic hybridization.

RESULTS: No POAG patient had evidence of chromosomal copy number alterations when compared to normal ethnically matched controls. Additionally, there was no evidence of somatic mosaicism in any tested POAG patient.

CONCLUSIONS: Chromosomal deletions and/or duplications were not detected in POAG patients as compared to controls. Other chromosomal imbalances such …

Wills Eye Hospital Papers

PURPOSE: To evaluate the knowledge glaucoma patients have about their disease and its treatment.

METHODS: One hundred and eighty-three patients were interviewed at the Glaucoma Service of Wills Eye Hospital (Philadelphia, USA, Group 1) and 100 at the Glaucoma Service of University of Campinas (Campinas, Brazil, Group 2). An informal, relaxed atmosphere was created by the interviewer before asking a list of 18 open-ended questions.

RESULTS: In Group 1, 44% of the 183 patients did not have an acceptable idea about what glaucoma is, 30% did not know the purpose of the medications they were taking, 47% were not aware …
