Degree, duration, and causes of visual loss in uveitis

Prolonged visual loss occurred in two thirds of uveitis patients, with 70 (22%) patients meeting the criteria for legal blindness at some point in their follow up. Older patients with bilateral inflammation and an increasing duration of reduced vision are at the greatest risk of severe visual loss (< or =6/60). CMO and cataract were responsible for visual loss in 64.5% of patients.
