optical coherence tomography findings in idiopathic perifoveal telangiectasia

purpose : to determine the optical coherence tomography (oct) findings in eyes with idiopathic perifoveal retinal telangiectasis (ipt) methods : this study is a retrospective review of patient charts, oct, fundus photography, related to 16 eyes (11 patients). results : the most consistent finding of idiopathic perifoveal telangiectasia seen in 93.7% of eyes (15 eyes) on oct was the presence of hyporeflective intraretinal spaces (cysts) in the absence of retinal thickening. other findings identified in ipt were: loss and disruption of the photoreceptor layer in 87.5% (14 cases), internal limiting membrane draping across the foveola related to an underlying loss of tissue in 25% (4 cases), an abnormal outward disfiguring of outer retinal layers which may be related to outer retinal atrophy in 37.5% (6 cases). conclusion : the oct findings in idiopathic perifoveal telangiectasia were characteristic and are helpful for better understanding its pathogenesis and visual function abnormalities.    iranian journal of ophthalmology 201123(3):21-26 © 2011 by the iranian society of ophthalmology
