Therapeutic effect of two methods of internal limiting membrane dissection on MHCI < 0.7 idiopathic macular hole

Abstract

AIM: To observe the clinical effects of different methods of internal limiting membrane peeling in vitrectomy in treatment of idiopathic macular hole(IMH)with macular hole closure index(MHCI)METHODS: Totally 88 patients(88 eyes)with MHCIRESULTS: At 6mo after operation, the closure rate of macular hole in group A was significantly higher than that in group B(91% vs 75%, Pvs 0.74±0.14, Pvs 23%, Pvs 9%, P>0.05).CONCLUSION: Extended internal limiting membrane dissection is more effective than standard internal limiting membrane dissection in the treatment of IMH with MHCI < 0.7, and the former is better for the recovery of retinal function.
