Purpose: To compare the outcomes of papillomacular bundle (PMB) sparing internal limiting membrane (ILM) peeling (group LP) and conventional ILM peeling (group CP) for treatment of idiopathic macular hole (MH) of ≤400 μm. Methods: Fifteen eyes were included in each group. In group CP, conventional 360° peeling was done, while in group LP, ILM was spared over PMB. The changes in peripapillary retinal nerve fiber layer (pRNFL) thickness and ganglion cell-inner plexiform layer (GC-IPL) thickness were analyzed at 3 months. Results: MH was closed in all with comparable visual improvement. Postoperatively, retinal nerve fiber layer (RNFL) was significantly thinner in the temporal quadrant in group CP. GC-IPL was significantly thinner in the temporal quadrants in group LP, whereas it was comparable in group CP. Conclusion: PMB sparing ILM peeling is comparable to conventional ILM peeling in terms of closure rate and visual gain, with the advantage of less retinal damage at 3 months.
