Diffuse Retinal Thickening due to Epiretinal Membrane in a Patient with Idiopathic Parafoveal Telangiectasia
MetadataShow full item record
Idiopathic parafoveal telangiectasia (IPT) is characterized by abnormal dilated or ectatic retinal capillaries with exudation. In many studies macular hole or pseudohole was demonstrated in patients with IPT. However, only one case with the coexistence of IPT and epiretinal membrane (ERNI) formation was reported before. In this study, we presented the retinal alterations of a patient with IPT admitted to our clinic with complaint of blurred vision for two months. A hyperreflective band refers to ERM, diffuse thickening and increased reflectance of inner retinal layers and cystic spaces in the inner nuclear layer of the retina were detected in horizontal optic coherence tomography (OCT) images of left eye. Due to the thickening of the inner retinal layers, foveal depression was lost. There was no full-thickness or partial-thickness retinal tissue defect in any OCT scan.
