[Idiopathic macular preretinal membrane in the elderly].

Idiopathic macular preretinal membrane was diagnosed in 14 patients, 4 males and 10 females, with age ranging from 47-72 years (mean 59.1 yrs) and a follow-up period from 1 month to 9 years (mean 2 yrs). The initial visual acuity varied from 0.05-1.5. Ophthalmoscopy and fluorescein angiography demonstrated fundus glinting light reflex, retinal fold, macular whitish preretinal membrane, distortion of the retinal vessels, and occasional microaneurysms and lamellar macular hole. The etiology was unknown. Progress of the disease was slow. Vision deteriorated in only 2 cases, and in 11 cases it remained stable for years.
