To evaluate less invasive MIVS for removing internal limiting membranes (ILM) without indocyanine green (ICG) for treating epiretinal membrane (ERM).
MIVS (23/25-gauge) was performed in 65 eyes with metamorphopsia due to ERM. The ILM was removed without ICG in all cases.
The visual acuity (VA) (logMAR) improved from 0.18 to 0.09 and 0.04 (P<0.001 for both) after 1 and 6 months, respectively. Multivariate logistic regression analyses revealed that healthy IS/OS and preoperative visual acuity are prognostic factors for good vision(P<0.05). An improvement at least 0.3 logMAR was, however, observed in only 16 (25%) eyes. Regarding a prognostic factor of postoperative VA exceeding 20/20, only a preoperative visual acuity was found by maltifactorial analysis(p<0.01). No ERMs recurred.
MIVS with peeeling of ILM no usage of ICG is effective and safe reducing a rate of ERM recurrence. SInce level of visual improvement is limitted, early vitrectomy is recommended to stabilize postoperative VA at higher level.
