To evaluate the efficacy of Combined subconjunctival with subscleral Ologen implantation in glaucoma filtering surgery.
15 eyes of 15 patients underwent fornix based trabeculectomy with insertion of ologen implant both subsclerally and subconjunctivally (double ologen) without the use of Mitomycin-C/5-Flurouracil. All patients had a minimum of 12 months follow up. Pre-operative data and post-operative data at 1 week, 1 month, 3 months, 6months and thereafter every 6 months for BCVA, applanation tonometry, bleb morphology & leaks, lens status, antiglaucoma medications, perimetry & any complications were noted.
The average age of patients was 50.86±14.76yrs (range 18-68 years). The male:female ratio was 10:5. The diagnosis were varied with 3 patients having Juvenile open angle glaucoma, 4 patients with Primary open angle glaucoma, 8 patients with Primary angle closure glaucoma. The mean preoperative IOP was 40.67±7.88mmHg. The average follow up was 18.5±4.7mths, with a minimum of at least 12mths. Postoperatively, the IOP at 3mths was 11.13±2.74mmHg; 6mths was 12.11±2.14mmHg; 12mths was 13.33±2.69mmHg. All patients had IOP≤18mmHg with no additional antiglaucoma medications. The preoperative & postoperative BCVA in LogMAR was 0.25±0.21 and 0.28±0.22 (p=0.239). 2 patients had shallow anterior chamber in the initial postoperative day, which was reformed and subsequently patients did well. 1 patient had choroidal detachment and one patient required resutring of conjunctiva in initial postoperative days.
Trabeculectomy with implantation of Ologen implant both subsclerally and subconjunctivally appears to offer encouraging short-term results in terms of IOP control in eyes with primary adult glaucoma.
