Normal eye/diagnosis diagnostic technique fluorescein angiography ophthalmology. Fundus Fluorescein Angiography (FFA) is a specialist ophthalmic test to visualise the retinal vasculature. Ultra-wide field fluorescein angiography revealed various fluorescence features in the periphery of normal eyes, providing a basis for interpreting normal and pathological changes in peripheral retina and an important reference for clinical work. Far peripheral retinas were found to have mottled florescent band in 42.17% eyes, ground glass hyperfluorescence in 84.34% eyes, granular hyperfluorescence in 12.65% eyes, local mottled fluorescence in 10.84% eyes, vascular anastomosis with a peripheral avascular area in 36.23% eyes, invisible capillary details in 50.67% eyes, vessels passing through the ora serrata in 16.98% eyes, late-phase slight leakage in 32.53% eyes, angiectasis in 18.67% eyes, and microaneurysm in 34.94% eyes. Normal values of a fluorescein angiogram include normal retinal vessels, retina, and choroidal circulation. Slight cataract were present in 64 eyes (38.55%), low to moderate myopia in 50 eyes (30.12%), and unspecified visual disturbances in 52 eyes (31.33%). obstructions, neovascularization, microaneurysms, abnormal capillary permeability, and defects of the retinal pigment epithelium. The mean patient age was 40.78 ± 10.94 years (range: 20-65 years) with a female-to-male ratio of 0.98. The retina is the layer of eye tissue that sends visual information to your brain.
Four different non-vascular and six vascular-associated fluorescence features in far peripheral retina were analyzed.Ī total of 166 eyes in 83 patients met the inclusion criteria. Fluorescein angiography is an imaging test to view the blood vessels in your retina. To analyze the peripheral retinal fluorescence characteristics of normal fundus on ultra-wide field fluorescein angiography (UWFA) images. The appearance of the far peripheral retina in normal eyes was observed using an Optos ultra-wide field fluorescein angiography imaging system.Ī cross-sectional study of ultra-wide field pseudocolor and angiography images obtained using the Optos 200Tx.
