Pseudoangiomatous Retinal Gliosis

A 54-year-old Hispanic male presented with decreased vision in the right eye over 3 months. Dilated fundus exam of the right eye showed a geographic area of chorioretinal alteration in the far temporal periphery at 9 o’clock, a gliovascular retinal mass superiorly at 12 o’clock with surrounding vitreous adhesion, opacification and lipid exudation extending both temporally and nasally in the peripheral retina. Optical coherence tomography showed an epiretinal membrane. B-scan showed a mounded lesion in the superior quadrants with irregular internal appearance (mostly hyperechoic) and structure. The patient was diagnosed with “pseudoangiomatous retinal gliosis”, which is a reactive grey-pink nodular gliotic mass secondary to ischemia, trauma, inflammation, etc. It may be cause lipid exudation, exudative RD, vitreous hemorrhage, and epiretinal membrane. It is usually observed if not causing visual symptoms. Smaller lesions can be managed with a combination of laser, PDT, and anti-VEGF injections. Larger lesions can be managed with plaque brachytherapy.
