During retinal detachment surgery, a drainage retinotomy facilitates subretinal fluid removal from the posterior pole when a retinal tear provides insufficient drainage. Use of this technique is surgeon-dependent due to the inherent localized retinal damage and concern for complications. This review examines visual outcomes and post-operative complications for retinal detachments repaired with the aid of a drainage retinotomy.
A retrospective chart review was performed for all rhegmatogenous retinal detachment (RRD) repairs at our academic institution from 2013 to 2016. We examined primary RRDs repaired with a standard surgical technique: 23-gauge pars plana vitrectomy with a drainage retinotomy, endoscopic laser photocoagulation, and perfluoropropane (C3F8) gas tamponade. Patients were divided into three groups based on macula status: macula-off; macula partially-off (fovea-on), and macula-on retinal detachments. Data was collected on patient demographics, pre-existing ocular conditions, location of detachment, location and number of breaks, pre/post-operative visual acuity, and post-operative complications. Exclusion criteria included diabetic retinopathy, previous retinal detachment, or previous retinal surgery in the affected eye.
A total of 167 eyes met the criteria, including 95 macula-off, 25 macula partially-off, and 47 macula-on RRDs. Final LogMAR visual acuity was 0.54 ± 0.54 for macula-off; 0.13 ± 0.18 for partially-off; and 0.10 ± 0.14 for macula-on at an average follow-up of 13.5 months after surgery. Twenty-one patients (12.6%) had a re-detachment during their follow-up period. Forty-four patients (26.3%) developed post-operative epiretinal membrane, with six patients (3.5%) requiring epiretinal membrane removal. Two patients (1.2%) developed intraoperative choroidal effusion, and one patient (0.6%) had a post-operative choroidal detachment.
Our results for RRDs repaired with the aid of a drainage retinotomy demonstrate similar outcomes to previously published data on RRDs repaired without a drainage retinotomy. A drainage retinotomy can facilitate subretinal fluid removal and retinal reattachment without increasing complication rates. Future studies should be conducted to evaluate for significant visual field defects from the retinotomy site.
