PURPOSE:To analyze anatomical outcomes, visual acuity results and secondary epirretinal membrane (ERM) formation rates in patients with macula-off retinal detachment who underwent peeling of the internal limiting membrane (ILM).
Ophthalmology Department of Hospital de Braga, Portugal
Retrospective study including all patients, operated by a single surgeon, who underwent vitrectomy for macula-off retinal detachment during the year 2014 in our department. ILM peeling was performed in all patients. Primary anatomical success, Best Corrected Visual Acuity (BCVA) by decimal scale, secondary epirretinal membrane formation rates and subjective visual complaints were evaluated.
Forty-eight patients were submitted to vitrectomy surgery in 2014 due to primary macula-off retinal detachment. ILM peeling was performed in all the patients. Mean patient age (± standard deviation SD) was 60.2±17 years. Mean follow-up time was 6.2 months. Mean pre-operative visual acuity was 0,31±0.21 on decimal scale. All patients were rendered pseudophakic at the time of vitrectomy. A successful anatomical result (complete retinal attachment without tamponading agent) was achieved after the first surgery in 97.4% of the patients. ILM peeling was not associated with complications either intra or post-operatively. At the final follow-up, no epirretinal membrane had been observed. Mean final visual acuity was 0.52±0.27.
Epiretinal membrane formation rate is estimated to be around 12% after vitrectomy for retinal detachment when the ILM is not peeled. We observed no epiretinal membrane formation in our study. Mean visual acuity improved significantly after vitrectomy with ILM peeling. The procedure was safe as no intra or post-operative complications were observed. Routine ILM peeling in non-complicated macula-off retinal detachment seems to be an effective way to prevent secondary ERM formation after vitrectomy.
