Fundus changes in sarcoidosis. Review of 33 patients with histological confirmation.

A series of 33 patients with histological evidence of sarcoidosis and a retinopathy is reviewed. The fundus can be involved in the absence of anterior uveitis and involvement may be grossly asymmetrical. The most common lesion was a retinal periphlebitis which can progress to occlusion and neovascularization at the same site or at the optic disc. Focal chorio-retinal changes frequently occur, usually without serious visual loss. Central retinal vein or large branch vein occlusions did not occur and the disease appears primarily to affect the smaller retinal veins.
