Study investigates role of PVD and VMA in progression of AMD

A higher incidence of vitreoretinal interface abnormalities was found in patients with exudative age-related macular degeneration as compared with patients with dry AMD and normal subjects, according to a study. The study included 206 eyes of 138 patients divided into three groups: exudative AMD, nonexudative AMD and age-matched controls. Presence of posterior vitreous detachment (PVD) and vitreomacular adhesion (VMA) was evaluated by B-mode ultrasonography and spectral-domain OCT, respectively, at baseline, 6 months and 12 months.
