Abstract

We studied 28 eyes presenting with subretinal neovascular membrane by means of clinical evaluation and fluorescein angiography. Each patient was an adult under 50 years of age. None of the patients were treated with laser photocoagulation or operation. The patients included 7 males(9 eyes) and 17 females(19 eyes). Idiopathic subretinal neovascular membrane was noted in 71.4% and myopic subretinal neovascular membrane in 28.6%. Visual acuity at the first visit was from finger count to 20/25. Visual acuity of 19 eyes(67.9%) was above 20/100. In 62.5% of the cases, the size of the lesion was less than half the diameter of the disc. Subfoveal type was noted in 75.0%. Visual acuity was maintained or improved in 75.0% and decreased in 25.0%. The subretinal neovscular membranes in patients who were under 50 years of age were mostly small and idiopathic, and located at the subfovea. These patients had good visual acuity compared to patients with subretinal neovascular membrane secondary to age-related macular degeneration.
