We report the case of a 60-year-old woman who presented with metamorphopsia and progressive vision loss in the right eye. Fundus examination revealed an elevated, white-yellow mass in the peripheral inferotemporal retina, with massive retinal exudation, proliferative vitreoretinopathy, and retinal detachment. Pars plana vitrectomy with tumor endoresection was performed, and a complete excisional biopsy of the lesion was obtained by removing the tumor through the anterior chamber. Histopathological analysis of the specimen confirmed a diagnosis of peripheral, focal, nodular retinal gliosis. Postoperatively, visual function improved greatly, with no recurrence of the disease at 12 months' follow-up. Focal nodular retinal gliosis is a rare, non-neoplastic proliferation of retinal glial cells, with a vascular component. In our case, surgical treatment with pars plana vitrectomy facilitated accurate diagnosis and resulted in effective management of the retinal tumor and associated complications. [ABSTRACT FROM AUTHOR]
