Abstract
Purpose: :
To evaluate less invasive MIVS for removing internal limiting membranes (ILM) without indocyanine green (ICG) for treating epiretinal membrane (ERM).
Methods: :
MIVS (23/25-gauge) was performed in 65 eyes with metamorphopsia due to ERM. The ILM was removed without ICG in all cases.
Results: :
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.
Conclusions: :
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.
