Abstract
Purpose: :
to describe the changes observed with Stratus Optical Coherence Tomography (OCT) in Group 2A Idiopathic Juxtafoveolar Retinal Telangiectasis (IJRT).
Methods: :
The files of 13 patients (25 eyes) were retrospectively reviewed. All eyes underwent OCT 3 examination comprising 6 radial scans, fundus color photography and fluorescein angiography. Retinal foveal thickness (FT) and Central Foveal Thickness (CFT) were calculated from software mapping. OCT data were compared to fundus photography and fluorescein angiography.
Results: :
Foveal cystoid spaces, either very small or more prominent, were present in 20/25 eyes. Some degree of Inner segment/Outer Segment photoreceptor (IS/OS PR) junction line disruption was observed in 18 eyes as from stage 2 of IJRT, and intraretinal pigmentary proliferation, in 8. A foveal detachment without subretinal new–vessels was also present in 2 eyes. Despite these abnormalities, CFT was below or within the range of normal values in all eyes, and FT, in 23/25 eyes. In the more advanced cases severe disruption of IS/OS PR junction and outer retina atrophy were seen.
Conclusions: :
Early in the evolution of of Group 2A IJRT, OCT examination disclosed intraretinal cystoid spaces without foveal thickening, and IS/OS PR junction line disruption. Foveal thinning was present in later stages
