Patients were classified into successful and unsuccessful groups. Success was defined as retinal reattachment, silicone oil removed, and best-corrected visual acuity (BCVA) \u22655\/200 at the final follow-up visit.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>Forty-three eyes (84.3%) were successfully reattached at the last follow-up. Seventeen (33.3%) eyes were deemed successful and 34 (66.7%) eyes unsuccessful according to our criteria. Compared with the successful group, eyes in the unsuccessful group had more eyes with preoperative BCVA &lt;5\/200 (<jats:italic toggle=\"yes\">P<\/jats:italic> &lt; 0.001), preoperative BCVA of hand motion or worse (<jats:italic toggle=\"yes\">P<\/jats:italic> = 0.002), preoperative flare \u2265Grade 2+ (<jats:italic toggle=\"yes\">P<\/jats:italic> = 0.03), preoperative posterior breaks (<jats:italic toggle=\"yes\">P<\/jats:italic> = 0.02), previous retinectomy (<jats:italic toggle=\"yes\">P<\/jats:italic> = 0.04), and final postoperative hypotony (intraocular pressure \u2264 5 mmHg) (<jats:italic toggle=\"yes\">P<\/jats:italic> = 0.005). Eyes with silicone oil removed were more likely to have BCVA \u22655\/200 (<jats:italic toggle=\"yes\">P<\/jats:italic> &lt; 0.001) at the final follow-up visit. Location of patients &gt;100 miles (<jats:italic toggle=\"yes\">P<\/jats:italic> = 0.04) from Detroit and preoperative BCVA of hand motion or worse (<jats:italic toggle=\"yes\">P<\/jats:italic> = 0.01) were significantly associated with failure in the logistic regression analysis.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion:<\/jats:title>\n            <jats:p>Success after repeat surgery for proliferative vitreoretinopathy should include ambulatory vision, retinal reattachment, and silicone oil removal. We identified several preoperative and perioperative factors that were associated with success in the bivariate and logistic analyses. The decision to perform surgical reoperation in these patients should be based on multiple factors, most importantly preoperative BCVA.<\/jats:p>\n
