PURPOSE: To compare the anatomical and functional outcomes of vitrectomy involving complete internal limiting membrane peeling (CP) with those of vitrectomy involving fovea-sparing internal limiting membrane peeling (FSP) for the treatment of macular holes measuring >250 µm. METHODS: This prospective, randomized, comparative study included 46 eyes with a medium or large macular hole that was randomized to undergo complete (CP group) or fovea-sparing (FSP group) internal limiting membrane peeling during vitrectomy. The main outcome measures included the foveal retinal sensitivity, visual acuity, and central retinal thickness. RESULTS: Both groups showed significantly improved foveal retinal sensitivity after surgery; the mean foveal retinal sensitivity change at 12 months after surgery was +2.8 ± 2.1 dB in the CP group and +7.2 ± 2.3 dB in the FSP group. The visual acuity also showed a significant improvement in both groups, with no significant differences in values at any time point. Regarding central retinal thickness, there was a significant decrease in the CP group and no change in the FSP group. Nicks or dimples in the inner retinal layers were visible in the fovea and perifovea of nine eyes in the CP group. CONCLUSION: Our findings suggest that both CP and FSP are safe and effective treatments leading to functional and anatomical improvements in patients with all size macular holes. However, the fovea-sparing technique may provide better functional outcomes because of a greater improvement in foveal retinal sensitivity.

Abstract

PURPOSE: To compare the anatomical and functional outcomes of vitrectomy involving complete internal limiting membrane peeling (CP) with those of vitrectomy involving fovea-sparing internal limiting membrane peeling (FSP) for the treatment of macular holes measuring >250 µm. METHODS: This prospective, randomized, comparative study included 46 eyes with a medium or large macular hole that was randomized to undergo complete (CP group) or fovea-sparing (FSP group) internal limiting membrane peeling during vitrectomy. The main outcome measures included the foveal retinal sensitivity, visual acuity, and central retinal thickness. RESULTS: Both groups showed significantly improved foveal retinal sensitivity after surgery; the mean foveal retinal sensitivity change at 12 months after surgery was +2.8 ± 2.1 dB in the CP group and +7.2 ± 2.3 dB in the FSP group. The visual acuity also showed a significant improvement in both groups, with no significant differences in values at any time point. Regarding central retinal thickness, there was a significant decrease in the CP group and no change in the FSP group. Nicks or dimples in the inner retinal layers were visible in the fovea and perifovea of nine eyes in the CP group. CONCLUSION: Our findings suggest that both CP and FSP are safe and effective treatments leading to functional and anatomical improvements in patients with all size macular holes. However, the fovea-sparing technique may provide better functional outcomes because of a greater improvement in foveal retinal sensitivity.
