بررسي مقايسه اي نتايج و عوارض عمل ترابكولكتومي با و بدون بخيه موقت

Purpose: To compare the short and long-term efficacy and complications of releasable suture vs conventional interrupted suture for scleral flap in trabeculectomy. Methods: In a prospective randomized clinical trial, 42 eyes of 42 consecutive patients requiring trabeculectomy for uncontrolled primary glaucoma underwent conventional trabeculectomy (group A) and trabeculectomy with releasable sutures (group B); 21 eyes of 21 patients for each group. Short-term hypotony related complications and long-term intraocular pressure were measured and compared. Results: The mean follow up was 11.7 ± 6.5 months in group A and 9.4 ± 6.4 months in group B. The mean + SD final intraocular pressure at the end of follow up period was 13.95 ± 4 mmHg in group A and 14.57 ± 3 mmHg in group B (P= 0.58). Mean reduction in intraocular pressure at the end of follow up was 54.5% in group A and 56% in group B. Final intraocular pressure was controlled (IOP 20mmHg) without medications in 15 patients in group A giving a success rate of 71.4% and in 14 patients in group B giving a success rate of 66.7%. Flat anterior chamber (grade III) was observed in 2 eyes in group A but in no eyes with releasable suture. At the end of follow up, the two groups were similar regarding intraocular pressure and need for ocular hypotensive medication. Conclusion: Releasable scleral flap sutures reduce the incidence of hypotony and related complication without any effects on long-term control of intraocular pressure and is an effective way with no extra cost or instrument.
