Main outcomes included the retinal reattachment rate, final best-corrected visual acuity (BCVA), postoperative intraocular pressure, extent of retinotomy, and complications.Results: Final retinal reattachment rates with silicone oil tamponade were 100%. The mean logarithm of the minimal angle of resolution (logMAR) BCVA was significantly improved (P = 0.001). Positive correlation was found between the extent of retinotomy and both preoperative logMAR BCVA (r = 0.663, P = 0.002) and postoperative logMAR BCVA (r = 0.619, P = 0.005). There was no correlation between the extent of retinotomy and the change in preoperative and postoperative logMAR BCVA (r = –0.267, P = 0.268). Negative correlation was found between preoperative logMAR BCVA and the change in logMAR BCVA (r = –0.587, P = 0.008). There was no correlation between the extent of retinotomy and the intraocular pressure at the final visit (r = –0.316, P = 0.188). Corneal decompensation due to silicone oil in the anterior chamber occurred in one eye.Conclusion: Removal of subretinal proliferative tissue with retinal turnover seems to be an effective procedure.Keywords: proliferative vitreoretinopathy, retinotomy, retinal turnover, subretinal proliferative tissue, under direct visualization
