ORAL CURCUMIN TO REDUCE RISK OF PROLIFERATIVE VITREORETINOPATHY FOLLOWING RHEGMATOGENOUS RETINAL DETACHMENT REPAIR.

PURPOSE To evaluate outcomes of patients who underwent rhegmatogenous retinal detachment repair and were started on oral curcumin for proliferative vitreoretinopathy (PVR) prevention. METHODS Retrospective, observational case series of eyes of patients undergoing high-risk rhegmatogenous retinal detachment repair that was started on curcumin postoperatively. Recommended dosage was 500 mg twice daily for 30 days followed by 500 mg daily for 60 days. The primary outcome was recurrent PVR-related rhegmatogenous retinal detachment within 6 months and a single-surgery retinal reattachment rate. Secondary outcomes included epiretinal membrane formation, visual acuity, and curcumin safety profile. RESULTS Thirty-two eyes of 31 patients met the study inclusion criteria. Postoperatively, 2 eyes developed a PVR-related detachment (6.3%), and 2 eyes redetached due to new breaks without PVR (6.3%). Overall, single-surgery retinal reattachment rate was 87.5%. Single-surgery retinal reattachment rate without silicone oil was 92.6% (25/27). Of the 12 cases with Grade C PVR-related retinal detachment, the single-surgery retinal reattachment rate was 91.7%. Postoperatively, 7 eyes developed an epiretinal membrane (21.9%), of which 3 underwent epiretinal membrane removal (9.4%). No patient had gastrointestinal upset or anemia. CONCLUSION This proof-of-concept clinical study suggests that oral curcumin is well tolerated and warrants further investigation for its potential to reduce the risk of PVR after rhegmatogenous retinal detachment repair in eyes at higher risk of PVR.
