To assess the impact of inner limiting membrane peeling during vitrectomy for macula-involving retinal detachment on best-corrected visual acuity (VA).
Retrospective analysis of 89 eyes with primary macula-involving retinal detachment, which was undergoing vitrectomy, endolaser, retinotomy, endodrainage, and SF6 tamponade. Membrane-blue-assisted membrane peeling had been performed in 61 of the eyes (Group 1) but not in the other 28 (Group 2), which served as controls.
Age, lens status, and incidence of proliferative vitreoretinopathy 26.2% versus 39.3%; P = 0.23 in the 2 groups were comparable. The preoperative visual acuity (Early Treatment Diabetic Retinopathy Study letters) was 25.7 ± 27.9 in Group 1 and 28.8 ± 29.9 in Group 2 (P = 0.47). After surgery, these rose from 62.3 ± 30.5 (Group 1) and 34.2 ± 35.8 (Group 2) after 1 week (P = 0.090), through 83.1 ± 8.0 and 57.2 ± 32.4 at 1 month (P = 0.0005), to 92.1 ± 4.5 and 74.4 ± 23.1 Early Treatment Diabetic Retinopathy Study letters after 6 months (P = 0.0005). More than 6-month incidences of proliferative vitreoretinopathy (13.1% vs. 28.6%; P = 0.13) were similar, whereas the redetachment rate (9.8% vs. 32.1%; P = 0.014), the incidence of secondary epiretinal membranes (1.6% vs. 35.7%; P = 0.0005), and the revitrectomy rate were lower in group 1 (9.8% vs. 53.6%; P = 0.0005).
Inner limiting membrane peeling during vitrectomy for macula-involving retinal detachment may substantially contribute to the visual recovery, reducing the incidence of secondary epiretinal membrane formation.
