Idiopathic premacular gliosis in children and adolescents.

We treated three patients under 20 years of age who had idiopathic premacular gliosis, a disorder found primarily in patients older than 50 years of age. Initial visual acuity ranged from 20/20 to 20/50, remained unchanged in one patient, improved in one patient, and decreased in one patient. Final visual acuity ranged from 20/15 to 20/500 with an average follow-up of 60 months (range, ten to 102 months). Included in this series is a 6-year-old boy with idiopathic premacular gliosis. Children and adolescents with idiopathic premacular gliosis may develop progressive visual loss to a level where vitrectomy should be considered.
