![]() These findings may provide a reference for future studies addressing putative pathologic peripheral angiographic findings. There was a high prevalence of peripheral vascular anatomic variations in eyes expected to have normal peripheral retinal vasculature. A study of the fluoresceinangiographic appearance of the retina in normal subjects without ophthalmoscopically obvious pathological changes Author N V Nielsen PMID: 7164784 DOI: 10.1111/j. The prevalences of findings were: arteriovenous shunting (0.00%), vessels crossing the horizontal raphe (44.83%), right angle vessels (70.69%), terminal networks (77.59%), absence of capillary detail (98.28%), ground glass hyperfluorescence (87.93%), drusen (34.48%), and microaneurysms (41.38%). Fluorescein Angiography (FA) is a diagnostic test that utilizes a specialized camera and a fluorescein dye to analyze the blood supply to the retina. The normal retinal fluorescein angiogram I. One or more peripheral anomalies were noted in all patients (P < 0.01). Mean peripheral arterial filling time was 8.65 ± 2.54 seconds (range 3-15 seconds). Dye transit times, peripheral arteriovenous shunting, presence of vessels crossing the horizontal raphe, right angle vessels, terminal networks, absence of capillary detail, ground glass hyperfluorescence, peripheral drusen, and microaneurysms were evaluated.įifty-eight eyes of 31 patients met inclusion criteria. Adult patients with epiretinal membrane or choroidal nevi who underwent imaging with Optos 200 MA/200Tx were included. Retinal vasculitis (/rtnil vskjlats/) is recognized by the following codes as per the International Classification of Diseases (ICD) nomenclature: ICD-9 ICD 9 Data 362.18 Retinal Vasculitis ICD-10 ICD 10 Data H35.061 Retinal Vasculitis, right eye H35.062 Retinal Vasculitis, left eye H35. This study was an observational retrospective cohort study. The range of normal peripheral findings has not been characterized, yet is relevant to studies addressing putative peripheral retinal vascular pathology. Widefield photography and angiography provide access up to 200-degrees of the retinal periphery. ![]()
