Abstract
To determine if there is an association of vitreous attachment and wet age-related macular degeneration (AMD), diabetic macular edema, and retinal vein occlusion. Systematic review and metaanalysis. Sixteen of 1,025 articles were eligible. In wet AMD, the prevalence of vitreomacular adhesion and posterior vitreous detachment was 23% (654 eyes) and 41% (251), respectively. Vitreomacular adhesion prevalence was 2.15 times that of controls (95% confidence interval, 1.34-3.48; p = 0.002) and 2.54 times that of dry AMD (confidence interval, 0.88-7.36; p 0.09); posterior vitreous detachment prevalence was lower than controls (relative risk 0.77; confidence interval, 0.64-0.93; p = 0.007) and dry AMD (0.56; confidence interval, 0.27-1.14; p = 0.11). It was not possible to determine the prevalence of vitreous attachment in diabetic macular edema, but vitreomacular traction was present in 29% of 188 surgical cases. The prevalence of posterior vitreous detachment in eyes with central and branch retinal vein occlusion was 30% (56 eyes) and 31% (71 eyes), respectively, versus 25% (64 eyes) in controls. Observational studies of sufficient quality indicate that eyes with wet AMD have double the expected prevalence of vitreomacular adhesion and are less likely to have a posterior vitreous detachment. More controlled studies of diabetic macular edema and retinal vein occlusion are needed.
