Abstract：Objective To investigate the clinical value of a combination of internal limiting membrane peeling and retinotomy in the treatment of traumatic retinal detachment .Methods A prospective analysis was con-ducted on 49 eyes of 49 patients with retinal detachment caused by open eye injuries admitted in the hospital from 2012 to 2014.These patients were randomly divided into two groups: group A (22 eyes) received intra-operative extensive peeling of internal limiting membrane in combination with a large range of peripheral retinotomy ;group B (27 eyes) received conventional vitreous surgical treatment and extermination of retinal traction .During an average follow-up of 6 months to 2 years,postoperative visual recovery,the incidence of recurrent retinal detachment and postoperative incidence of epimacular membrane in the two groups were observed and compared .Results Preoper-ative PVR classification and vision were compared between the two groups ,with no statistically significant difference ( P>0.05);The incidences of recurrent retinal detachment during follow-up were as follows: postoperative retinal detachment occurred in 2 eyes (9.1%) in group A and 11 eyes (40.7%) in group B;chi-square value between the two groups was 6.229;and P value was 0.0125.Postoperative OCT examination showed epimacular membrane in 1 eye (4.5%) for group A and in 9 eyes (33.3%,χ2 =4.540,P=0.033) for group B.Conclusion For patients ith internal limiting membrane peeling at the posterior pole in group A ,the best corrected visual acuity after operation was comparable to that in group B ,with no statistically significant difference .However,the probabilities of occur-rence of recurrent retinal detachment and epimacular membrane in group A were lower than those in group B ,with statistically significant differences .
