Effect of Encircling Silicone Sponge for Retinal Detachment

120 eyes of 119 patients with retinal detachment were treated with an encircling silicone sponge scleral buckling in the department of Ophthalmolgy, Severance Hospital, Yonsei University Medical Center from September 1, 1988, to January 31, 1991. Results were as follow 107 eyes among 120 eyes (89.2%) showed anatomical success, and 54 eyes of them (45%) showed functional success. As the preoperative factors, the case of over 20/70 vision (100%, p>0.05, 100%, p0.05, 57%, p0.05,61%, p0.05, 54%, p<0.05) showed favorable anatomical and functional success rate. The presence and degree of the proliferative vitreoretinaopathy affected the anatomical and functional success rate, but the age of patients did not affect the success of surgery.
