A Clinical Study on Rhegmatogenous Retinal Detachment by Macular Involvement

ABSTRACT

We reviewed charts of 148 patients(148 eyes) who were diagnosed with rhegmatogenous retinal detachment and operated from January 1994 to December 1995 and followed for at least 3 months postoperatively at kangnam St. Mary's hospital. We compared preoperative findings, surgical methods, ultimate anatomic success and visual outcome by macular involvement, and evaluated the causes of decrease in visual acuity after operation. Fifty four eyes were A group without involved macula and 94 eyes were B group with involved macula. There were no differences betwetm the two groups according to age, sex distribution, preoperative refractive error and location of retinal breaks. In the eyes with detached macular(B group), the duration and the extent of retinal detachment and the numbers of retinal breaks were more than those of A Group. Postoperatively 52 eyes(96.3%) with spared macular and 84 eyes(89.4%) with detached macular were anatomically reattached. Forty two eyes(77.8%) with spared macula achived visual acuity of 0.3 or better, in contrast to 2.5 eyes(26.6%) with detached macula. The most common causes of decrease in visual acuity after operation were proliferative vitreoretinopathy, macular pucker, cystoid macular edma and subretinal hemorrhage.
