چکیده
INTRODUCTION Trabeculectomy is a commonly used surgical treatment for glaucoma. PURPOSE To evaluate the effectiveness of combination of permanent and releasable scleral flap sutures to minimize the immediate postoperative complications of trabeculectomy. MATERIALS AND METHODS This study was carried out in Department of Ophthalmology, B P Koirala Institute of Health Sciences, Dharan, Nepal. Forty one eyes of 34 patients undergoing trabeculectomy were randomized to undergo either conventional trabeculectomy (Group A= 20 eyes) or trabeculectomy with combination of permanent and releasable scleral flap sutures (Group B =21 eyes). The parameters studied were intraocular pressure (IOP), anterior chamber depth (ACD) and surgical complications over a period of 6 weeks. RESULTS Significantly higher number of eyes belonging to group A (14 eyes) had shallower anterior chamber than group B (7 eyes) on first post operative day (p=0.042). Six eyes (30%) in group A had peripheral or central irido-corneal touch in early postoperative period as compared to only one in Group B. Hypotony was noted in 3 eyes in each group. Two patients in group A required reformation of anterior chamber. Other surgical complications in the two groups were similar. Both the groups had a significant drop in IOP following surgery. However, there was no significant difference in the IOP between the two groups after 6 weeks (Group A: 10.95 +/- 3.03 mmHg vs. Group B: 12.29 +/- 4.67 mmHg; p=0.87). There was a significant drop in IOP following removal of sutures (15.19 +/- 6.15 mmHg to 13.19 +/- 6.13 mmHg; p=006) in group B. CONCLUSION Use of combination of permanent and releasable scleral flap sutures is a safe technique that significantly reduces the incidence of immediate postoperative shallow anterior chamber after trabeculectomy.

BACKGROUND The purpose of this study was to compare the outcomes of trabeculectomy using single sutures or releasable sutures. METHODS This retrospective study analyzed the medical records of 61 patients who had undergone trabeculectomy using single sutures (n = 33, 54.1%) or releasable sutures (n = 28, 45.9%). The scleral flap was secured with a mean 3.9 (range 3-5) single sutures in 33 pati...

PURPOSE Intraocular pressure and aqueous humor flow direction determined by the scleral flap immediately after trabeculectomy are critical determinants of the surgical outcome. We used a large-scale model to objectively measure the influence of flap thickness and shape, and suture number and position on pressure difference across the flap and flow of fluid underneath it. METHODS The model exp...
