특발성 황반원공에서 내경계막 제거여부 및 Indocyanine green의 사용여부가 수술결과에 미치는 영향

Abstract

The purpose of this study was to evaluate whether indocyanine green (ICG) staining of the retinal internal limiting membrane (ILM) and removal of ILM improves surgical and visual outcomes in idiopathic macular hole surgery. The records of 92 patients (93 eyes) with idiopathic macular hole who had undergone pars plana vitrectomy were retrospectively reviewed. Group 1 (31 eyes) underwent no ILM peeling, group 2 (51 eyes) a peeling of ILM stained 0.5% ICG dye, group 3 (12 eyes) an ILM peeling without use of ICG dye. We compared the anatomic and functional results of three groups. Postoperative anatomic closure rates of the macular hole was 91.4%(85 eyes) of ninety-three eyes, 76.2% in group 1, 98.0% in group 2, 100% in group 3. There was statistically significant difference among the three groups (p=0.002). The postoperative visual acuity improved all these groups, but there was no statistically significant difference of these groups in the postoperative functional success (p=0.709). The complication, such as macular hole reopen, occurred more in group 1 and 3 than group 2 (p=0.017). This study shows that the ICG-assisted peeling of ILM in idiopathic macular hole surgery influence statistically significant different in the postoperative results of anatomic closure, visual acuity, complication.
