Abstract

Abstract: : Purpose:To describe OCT findings in patients diagnosed with parafoveal telangiectasia (PT). Methods:A retrospective review of patient charts with a diagnosis of PT was performed. Data consisting of visual acuity, slit lamp examination, intraocular pressure, visual fields, fluorescein angiography and OCT was collected. The fluorescein angiography and OCT results were analyzed and compared. Results:Thirteen patients (24 eyes) were included in the study. Eight (62%) were females. Age ranged from 51 to 78 years. Two of thirteen patients (15%) were classified as Type IB PT (2 eyes), and eleven (85%) were classified as Type IIA PT (12 eyes). The main OCT findings were: a) increased tissue reflectivity in twenty three eyes (96%); b) intraretinal cystoid space in twelve eyes (50%); c) seven eyes (29%) had intraretinal pigment funduscopically, OCT detected dark intraretinal area under a hyperreflective band in five of these eyes (71%); d) lamellar hole in two eyes (8%). Fluorescein leakage was detected in all eyes. Conclusion:Increased tissue reflectivity is the most common OCT finding in PT. Although fluorescein leakage was detected in all eyes, only 50% showed visible cystoid spaces on OCT.
