Authors analysed the clinical characteristics and the surgical results of rhegmatogenous retinal detachment in 70 patients(71 eyes) who were operated GNUH from Feb. 1990 to Feb. 1992. The clinical characteristics of rhegmatogenous retinal detachment were as follows. The result was myopia(39.4%) as the most common associated ocular finding, one break(57.7%) as the number of break, two quadrants(33.8%) as the extent of retinal detachmenthole(53.5%) as the type of break and superior temporal portion(56.3%) and anterior portion including equator(83.1%) as the location of break. The success rate of first operation was 87.3% and the overall success rate of rhegmatogenous retinal detachment maintained anatomical attachment above 6 months and exeluded 3 cases of refused reoperation was 92.3%. The type of break extent of detachment and duration of detachment were not influenced to surgical success rate statistically(P>0.05). The most common cause of first operative failure was proliferative vitreoretinopathy(57%).
