OBJECTIVE: To investigate the phenotype and age-related penetrance of primary open-angle glaucoma (POAG) in Australian families with the most common Myocilin mutation (Gln368STOP).

DESIGN: Cross-sectional genetic study.

PARTICIPANTS: Eight pedigrees carrying the Gln368STOP mutation were ascertained from 1730 consecutive cases of POAG in the Glaucoma Inheritance Study in Tasmania.

METHODS: Index cases and available family members were examined for signs of glaucoma, and the presence of ...

OBJECTIVE: To report the spectrum of ophthalmic findings in patients with Stargardt dystrophy or fundus flavimaculatus who have a specific sequence variation in the ABCR gene.

PATIENTS: Twenty-nine patients with Stargardt dystrophy or fundus flavimaculatus from different pedigrees were identified with possible disease-causing sequence variations in the ABCR gene from a group of 66 patients who were screened for sequence variations in this gene.

METHODS: Patients underwent a routine ...

PURPOSE: Mutations of the forkhead transcription factor gene FOXC1 result in anterior segment anomalies. No description of the spectrum of defects resulting from a single point mutation of this gene exists in the ophthalmology literature. We have screened all available patients with Axenfeld-Rieger genes (PITX2 and FOXC1). In this report, we clinically characterize the spectrum of ocular and systemic manifestations in one family resulting from a previously reported point mutation ...

OBJECTIVE: To determine the safety and efficacy of subretinal gene therapy in the RPE65 form of Leber congenital amaurosis using recombinant adeno-associated virus 2 (rAAV2) carrying the RPE65 gene.

DESIGN: Open-label, dose-escalation phase I study of 15 patients (range, 11-30 years of age) evaluated after subretinal injection of the rAAV2- RPE65 vector into the worse-functioning eye. Five cohorts represented 4 dose levels and 2 different injection strategies.

MAIN OUTCOME MEASURES: ...

PURPOSE: To evaluate the outcome of intravitreal injection of aflibercept in cases with exudative age-related macular degeneration, (AMD) resistant to injections of bevacizumab or ranibizumab.

DESIGN: Retrospective observational case series.

METHODS: A retrospective chart review at a single institution was conducted to identify patients with exudative AMD and choroidal neovascularization (CNV) in 1 or both eyes resistant to treatment with ranibizumab or bevacizumab who were switched to ...

OBJECTIVE: To weight the rod-, cone-, and melanopsin-mediated activation of the retinal ganglion cells, which drive the pupil light reflex by varying the light stimulus wavelength, intensity, and duration.

DESIGN: Experimental study.

PARTICIPANTS: Forty-three subjects with normal eyes and 3 patients with neuroretinal visual loss.

METHODS: A novel stimulus paradigm was developed using either a long wavelength (red) or short wavelength (blue) light given as a continuous Ganzfeld stimulus ...

PURPOSE: To correlate visual acuity of patients with Leber's congenital amaurosis (LCA) and early childhood-onset retinitis pigmentosa (RP) with mutations in underlying LCA genes.

DESIGN: Multicentered retrospective observational study.

PARTICIPANTS: After exclusion of 28 subjects, 169 patients with the diagnosis of LCA and 27 patients with early childhood-onset RP were included in the study because the underlying mutations in AIPL1, GUCY2D, RDH12, RPE65, CRX, CRB1, RPGRIP1, CEP290, ...

Age-related macular degeneration (AMD) is the most common cause of vision loss in developed countries. A defining characteristic of this disorder is the accumulation of material between Bruch's membrane and the retinal pigment epithelium (RPE), first as microscopic basal deposits and later as clinically evident drusen. The pathogenesis of these deposits remains to be defined. Biochemical and genetic studies have suggested that inflammation and complement activation may play roles in AMD. ...

PURPOSE: To evaluate genotypic and macular morphologic correlations in patients with RPE65-, CEP290-, GUCY2D-, or AIPL1-related Leber congenital amaurosis (LCA) using spectral-domain optical coherence tomography (SD-OCT).

METHODS: SD-OCT macular scans were performed in 21 patients, including 10 with RPE65, 7 with CEP290, 3 with GUCY2D, and 1 with AIPL1 mutations. An image processing software was used to manually draw segmentation lines by three observers. Lamellar structure was evaluated ...

Retinitis pigmentosa (RP) is a genetically heterogeneous heritable disease characterized by apoptotic death of photoreceptor cells. We used exome sequencing to identify a homozygous Alu insertion in exon 9 of male germ cell-associated kinase (MAK) as the cause of disease in an isolated individual with RP. Screening of 1,798 unrelated RP patients identified 20 additional probands homozygous for this insertion (1.2%). All 21 affected probands are of Jewish ancestry. MAK encodes a kinase ...

BACKGROUND AND OBJECTIVES: Mutations of the peripherin/RDS gene have been reported in autosomal dominant retinitis pigmentosa, pattern macular dystrophy, and retinitis punctata albescens. We report herein the occurrence of three separate phenotypes within a single family with a novel 3-base pair deletion of codon 153 or 154 of the peripherin/RDS gene.

DESIGN: Case reports with clinical features, fluorescein angiography, kinetic perimetry, electrophysiological studies, and molecular ...
