Abstract
Background: Neovascular glaucoma is common secondary glaucoma at high risk for failure of glaucoma filtering surgery. Recently, trabeculectomy with adjunctive mitomycin C trabeculectomy has been tried to improve the surgical success rate of conventional trabeculectomy. But, the long-term effects of mitomycin C trabeculectomy for neovascular glaucoma are unknown. Thus, we evaluated the long-term effects of mitomycin C trabeculectomy and its prognostic factors influencing the outcome. Materials and Methods: Medical records of 62 eyes of 55 neovascular glaucoma who had undergone mitomycin C trabeculectomy were retrospectively reviewed. Surgical success was defined as intraocular pressures of 21 mmHg or less with or without glaucoma medications and no loss of light perception. Surgical failure was defined as postoperative loss of light perception in patients with preoperative vision better than light perception, additional glaucoma surgery, or phthisis bulbi in patients with preoperative vision of no light perception. Results: Postoperative success was obtained in 37 (60%) out of 62 eyes after mean followup period of
신생혈관녹내장에 대한 MMC 섬유주절제술의 효과와 그 예후에 영향을 미치는 요인에 대해 알아보고자 하였다. 신생혈관녹내장으로 진단하고 MMC 섬유주절제술을 시행한 55명, 62안을 대상으로 의무기록을 후향적으로 조사하였다. 수술 성공 여부의 기준은 술후 안압하강제 사용에 관계없이 술후 최종 안압이 21 mmHg이하이며 시력상실이 없는 경우를 성공으로 판정하였고, 술전 시력이 광각이상의 환자에서 광각이 소실된 경우와 광각무인 환자에서 안구위축이 발생한 경우 및 안압하강을 위해 추가적 녹내장수술을 시행한 경우는 수술실패로 판정하였다. 평균
