متن کاملThe Effect of Treatment of Idiopathic Intracranial Hypertension on Prevalence of Retinal and Choroidal Folds.
PURPOSE We described 3 types of folds in the retina and a crease in the outer retina associated with papilledema owing to idiopathic intracranial hypertension (IIH) at presentation. We report the change in folds relative to treatment of IIH over the 6 months. METHODS In this substudy of a randomized clinical trial, study eyes of subjects assigned to acetazolamide (ACZ, n = 44) or placebo (PLB...
