• Supplemental photocoagulation on the buckle appears to be a useful therapeutic modality in selected cases of persistent retinal detachment. In a retrospective review, 71 (63%) of 113 eyes were successfully treated with photocoagulation, thus avoiding the need for surgical revision. Median response time between treatment and postoperative subretinal fluid absorption in the successfully treated eyes was two days, with the majority responding within one day. The one favorable prognostic factor was the use of a soft silicone segmental sponge. Unfavorable prognostic factors included the following: contour of subretinal fluid (combined, ie, both anterior and posterior to the buckle); excessive amount of subretinal fluid; inadequate support of break(s); multiple drainages at first operation; rolled edge in association with a giant break; and residual vitreous traction on the break. Postoperative photocoagulation alone on the buckle did not appear to influence the rate of development of premacular fibroplasia or proliferative vitreoretinopathy.
