Abstract
PURPOSE: To evaluate the status of the macula after surgical treatment of proliferative vitreoretinopathy (PVR). METHOD: Biomicroscopic and fluorescein angiographic examination of the macula was performed in 58 eyes of 58 patients 6 to 7 months after complete gas absorption for rhegmatogenous retinal detachment complicated by PVR (grade C1 to D3). RESULTS: Macular changes were found in 46 eyes (79.3%), and included: cystoid macular edema (30 eyes; 51.7%), epiretinal membranes distant from the macula (3 eyes; 5.1%), macular pucker (7 eyes; 12%), subretinal membranes (5 eyes; 8.6%), and subretinal pigment dispersion (5 eyes; 8.6%). In five eyes, two distinct changes were found. Optic dye leakage occurred in 4 eyes (6.8%). CONCLUSION: Biomicroscopic and fluorescein angiographic examination of the macula can be used to determine why eyes in which rhegmatogenous retinal detachment complicated by PVR is successfully repaired do not achieve good recovery of vision. Spontaneous improvement or disappearance of postoperative cystoid macular edema, with late improvement in visual acuity, may occur in a small number of patients.
