Abstract

 Objective: To find the effectiveness of trabecular aspiration in reducing (IOP) Intraocular pressure in patients with pseudoexfoliation syndrome. Materials and Methods: The patients with pseudoexfoliation glaucoma visiting ophthalmology Outpatient department of R.L. Jalappa hospital were taken for this study. 44 patients out of 56 patients came for the followup. The patients were consecutively segregated

into 2 groups. Group 1 underwent trabecular aspiration and Group 2 underwent trabeculectomy. Trabecular aspiration was done with trabecular aspiration probe directed against trabecular meshwork at 6 o’ clock position. Suction pressure between 100 to 200 mm Hg was applied over 5 to 6 clock hours. Trabeculectomy was done in group 2 patients. In this technique a fistula was created to allow aqueous outflow from anterior chamber to subtenons space under guard of scleral flap. It is a prospective
randomised control trial. Both the group patients were followed for 1 week, 2 weeks,1 month, 2 months and 3 months. Intraoperative and postoperative complications like hyphaema,shallow anterior chamber were noted. Results: The mean IOP was 16.27 mm Hg and 12.6 mm Hg in Group 1 and Group 2 respectively on first postoperative day. The p value of < 0.001 showed IOP was statistically significant between the two groups. First postoperative week showed mean IOP 16.18 mmHg in group 1 and 12.36 mm Hg
in group 2. p value being <0.001 showed the difference between IOP in two groups was statistically significant even upto three months. Conclusion: The IOP reduction was more in trabeculectomy group than trabecular aspiration group. Complications such as hyphaema and shallow anterior chamber were seen in trabeculectomy group.
