Abstract
- To investigate the effect of trabeculectomy with the modification of scleral flap, modified trabeculectomy with partially excised scleral flap(PESF) was performed in one eye and trabeculectomy with non-excised scleral flap(NESF) in the contralateral eyes of five rabbits. Postoperative histologic examinations were done on these eyes at 2 weeks after surgery. And 10 PESF and 12 NESF trabeculectomies was performed in 22 glaucoma patients for the control of intraocular pressure(IOP). Results of histologic examination showed less subconjunctival inflammation and fibrosis in PESF group than NESF group. IOP was controlled successfully in PESF(80%) and NESF(75%) group. Mean IOP was 14.7 +/- 4.1 mmHg in PESF group and 16.4 +/- 2.5 mmHg in NESF group at the 2 month follow-up visit. Duration of anterior chamber reformation was 10.7 days in PESF group and 8.9 days in NESF group. And cases of removal of releasable suture were 5 eyes in NESF group but none in PESF grup. This PESF trabeculectomy seems to be a safe and effective procedure that produces diffuse, persistent blebs and good control of IOP.
