Primary open-angle glaucoma (POAG) is the leading cause of irreversible blindness worldwide and has been associated with multiple genetic risk factors. The gene is a genetic susceptibility factor for POAG, and several single-nucleotide polymorphisms (SNPs) were shown to be associated with POAG in our own prior Primary Open-Angle African American Glaucoma Genetics (POAAGG) study genome-wide association study (GWAS). This study evaluated the association of the locus with baseline optic disc and clinical phenotypic characteristics of glaucoma patients from our African American cohort.

Purpose: To determine the accuracy of identifying referral-warranted retinopathy of prematurity (RW-ROP, defined as any zone I ROP, stage 3 or worse, or plus disease) from retinal image sets using three grading protocols: a single optic disk-centered image, a set of 3 horizontal images, and a 5-image set.

Methods: In this secondary analysis of images from the e-ROP study, a weighted sample of 250 image sets from 250 infants (125 with RW-ROP and 125 without RW-ROP) was randomly selected. The sensitivities and specificities for detecting RW-ROP and its components from a single disk center image, along with nasal and temporal retinal images, were calculated and compared with the e-ROP grading of RW-ROP of all 5 retinal images (disk center and nasal, temporal, superior, and inferior retinal images).

A number of sensory changes occur in the earliest stages of Parkinson's disease (PD), some of which precede the expression of the classic motor phenotype by years (e.g., olfactory dysfunction).

Background: The hang-back loop suspension surgical technique for rectus muscle recession offers potential advantages over the conventional rectus muscle recession, including better exposure at the site of scleral sutures, shorter procedure duration, and lower risk of scleral perforation. Previous reports suggest that the hang-back technique for lateral rectus recession for exotropia results in poorer surgical success and may require a different surgical dosage.

Methods: We compared strabismus in a nonrandomized series of 55 children with exotropia treated with conventional surgery or hang-back surgery.

Purpose: To identify risk factors for the development of choroidal neovascularization (CNV) and vision loss in the Fellow Eye Study of the Choroidal Neovascularization Prevention Trial.

Methods: Retrospective review of 121 patients enrolled in a multicentered, randomized, controlled trial. Patients had neovascular age-related macular degeneration in one eye and more than 10 large drusen in the other eye.
