Anatomic Success Of Retina Attachment And Postoperative Vision After Silicone Oil Removal Surgery: A Retrospective Study 1. Chen-Yu Hsu Kaohsiung Medical University Chung-Ho Memorial Hospital, Kaohsiung,Taiwan Purpose: To determine the anatomic success rate and postoperative vision after silicone oil removal surgery of different indications. Method: 28 eyes with RD treated with silicone oil tamponade, with subsequent silicone oil removal, in an institutional setting. Main outcome measures include anatomic success (complete retinal attachment), and BCVA after silicone oil removal. Result: Silicone oil was removal after a mean tamponade period of 17.5±12.5 months. In 8 (29%), 9 (32%), and 2 (7%) eyes, silicone oil was removed because of silicone oil emulsification, silicone oil in anterior chamber, and concomitant with others posterior segment surgery, respectively. Others 9 (32%) eyes received silicone oil removal accompanying with cataract surgery. The overall anatomic success rate after silicone oil removal (in 6 months) was 76%. Logistic regression showed that concomitant cataract surgery (odds ratio: 0.93, 95% CI:0.14 to 6.37) and previous sclera buckling (odds ratio: 5.33, 95% CI: 0.76 to 37.09)were not associated with anatomic success rate. Duration of silicone oil tamponade was statistically associated anatomic success rate (P=.049). Patients receiving concomitant cataract surgery with silicone oil removal had better BCVA than previous, but, without statistically significant difference. Anatomic success was associated with a significantly better BCVA. Conclusion: The indications of silicone oil removal, such as complication resolving, concomitant cataract surgery had no significant difference in anatomic success after silicone oil removal. But patients bad better BCVA after concomitant cataract surgery with silicone oil removal. Besides, longer duration of silicone oil tamponade had higher anatomic success after silicone oil removal. |
