PURPOSE To describe the pathophysiologic and the hemodynamic changes associated with branch retinal vein occlusion (BRVO) on the basis of selected angiographic observations from a cohort of patients with BRVO and related anomalies of retinal blood flow. DESIGN Retrospective, observational case series. PARTICIPANTS A total of 250 patients with incipient(More)
PURPOSE To describe the phenotype and genotype of patients with a diagnosis of oligocone trichromacy (OT). METHODS Six unrelated patients had a detailed ophthalmic examination including color vision testing, a Goldmann visual field test, fundus photography, and full-field electroretinography (ffERG). Five patients also underwent multifocal (mf)ERG,(More)
OBJECTIVES To evaluate comorbidity before and after the diagnosis of branch retinal vein occlusion to determine whether it is a consequence of arterial thickening and therefore could serve as a diagnostic marker for other comorbidities and to evaluate the risk factors for the development of such occlusion. DESIGN Case-control study with prospective(More)
PURPOSE To assess mortality in patients with central retinal vein occlusion (CRVO). DESIGN Registry-based cohort study. PARTICIPANTS AND CONTROLS Four hundred thirty-nine photographically verified CRVO patients and a control cohort of 2195 unexposed subjects matched by age and gender and alive on the date CRVO was diagnosed in the corresponding case. (More)
PURPOSE To assess the impact of branch retinal vein occlusion (BRVO), a condition related to arteriolar wall thickening, as a prognostic marker of mortality. DESIGN Long-term follow-up study comparing cases with background population. PARTICIPANTS Patients diagnosed with BRVO. METHODS Diagnosis of BRVO confirmed by fundus photographic records(More)
PURPOSE To present evidence that precipitation of hard exudate in the retina can occur after reduction of macular edema by successful photocoagulation treatment for retinal branch vein occlusion. METHODS A 59-year-old woman received argon laser retinal photocoagulation treatment for retinal branch vein occlusion over the primarily involved engorged area(More)
PURPOSE To describe two cases of strictly unilateral diabetic retinopathy with macular edema where the precipitating factor appears to have been retinal venous congestion. METHODS Retrospective interventional case study. RESULTS Examination of fundus photographic records demonstrated generalized venous dilation in the affected eyes years in advance of(More)
