Idiopathic preretinal macular gliosis: a retrospective study of 200 patients.

The charts of the last 200 patients with idiopathic preretinal macular gliosis (IPRMG) seen in the Retina Service of Montefiore Medical Center, Albert Einstein College of Medicine, were reviewed. We found that IPRMG is a disease of older people, tends to have a nonprogressive course, and rarely causes severe visual loss. In our series, 91.5% of the patients were older than 50 years of age, 80% of eyes lost less than two lines of vision, and only 4% of eyes had a visual acuity 20/200.
