Abstract
Purpose: To study the role of laser suture lysis in immediate trabeculectomyfailure.Material and Methods: This was a prospective case series study conducted atDepartment of Ophthalmology, Chandka Medical College Hospital Larkana,Pakistan from May 2007 to May 2015. 21 eyes of 20 patients who underwenttrabeculectomy for primary open angle glaucoma and encountered immediatetrabeculectomy failure were included in the study. Immediate trabeculectomyfailure was considered when IOP during first 48 hours after trabeculectomyremained above 25 mm Hg. Laser suture lysis was carried out with Nd: YAGLaser (1064 nm) or with frequency doubled Nd: YAG Laser (532 nm). The preprocedureand post-procedure IOP was noted and IOP below 18 mm Hg wasconsidered as successful laser suture lysis. Data entry and analysis was doneon SPSS version 20.Results: 12 (60 %) patients out of the total 20 patients were males and 8 (40 %)were females. The mean age ± standard deviation of patients was 61.45 ± 7.37years and the age range was 47 to 71 years. IOP came down to normal in all thecases after the laser suture lysis, without encountering any major complications.Mean IOP before laser suture lysis was 30.95 ± 2.20 mm Hg and mean IOP onehour after successful laser suture lysis was 13.38 ± 1.53 mm Hg.Conclusion: Laser suture lysis is a safe, effective and day care procedure in themanagement of immediate trabeculectomy failure.Keywords: Glaucoma, Trabeculectomy, failure, laser, suture.
