목적 : 망막박리 환자 중 유리체절제술시 실리콘기름을 주입한 눈에 술후 망막전막의 발생에 관여하는 인자를 알아보고자 하였다. 대상과 방법 : 93안을 대상으로 후향적 조사를 시행하였다. 남자가 52안(55.9%), 여자가 41안(44.1%)이었으며, 평균 연령은 51.8세였다. 결과 : 32안(34.8%)에서 망막전막이 발생하였으며, 평균 발생 시기는 술후 3.2개월이었다. 단변량분석에서 망막전막은 술중 망막냉동응고술을 시행한 경우, 박리의 범위가 2 상한을 넘는 경우, 술전 유리체출혈이 있는 경우 유의하게 많이 발생하였다(P<0.05). 다변량분석에서는 술중 망막냉동응고술을 시행한 경우, 술전 유리체출혈이 있는 경우에서 망막전막의 발생과 통계학적으로 유의한 관련이 있었다(P<0.05). 결론 : 실리콘 기름을 주입할 망막박리 안에서 술후의 망막전막 발생을 예방하기 위해 되도록 망막냉동응고술을 피하거나 필요한 최소한의 망막냉동응고술을 시행하고 유리체출혈을 완전하게 제거하는 것이 바람직하리라 생각된다.

Purpose: To evaluate the factors for postoperative formation of epiretinal membrane (ERM) in vitrectomized eyes with silicone oil tamponade for rhegmatogenous retinal detachment (RRD). Methods: Retrospective evaluation was performed in 93 vitrectomized eyes with silicone oil tamponade for RRD. Fifty-two (55.9%) were male and 41 (44.1%) were female, and the mean age was 51.8 years. Results: ERM was developed postoperatively in 32 eyes (34.8%) with a mean onset of formation of 3.2 months postoperatively. Univariate analysis revealed that ERM was significantly more frequent in the eyes receiving cryoretinopexy, in the eyes with RRD involving 2 quadrants or more, and in the eyes with preoperative vitreous hemorrhage(P<0.05). Multivariate analysis revealed that ERM was significantly more frequent in the eyes receiving cryoretinopexy and in the eyes with preoperative vitreous hemorrhage.(P<0.05). Conclusions: We conclude that avoiding or minimizing cryoretinopexy and completely removing vitreous hemorrhage are important to prevent ERM from developing in the cases of vitrectomy with silicone oil tamponade for RRD.
