EFFECTIVENESS OF LASER SUTURE LYSIS AFTER TRABECULECTOMY WITH EARLY- POSTOPERATIVE HIGH INTRAOCULAR PRESSURE

Objective: to evaluate the effectiveness of laser suture lysis (lsl) in patients with early high intraocular pressure (iop) after trabeculectomy. material and methods: fourty seven eyes of 42 patients who had high iop and bleb formation after ocular massage in early postoperative period after trabeculectomy and undergone lsl between 2005 and 2013 were evaluated resrospectively. results: twenty-two patients were female, 20 patients were male and the mean age was 62.1±16 (34-81). lsl was performed once in 22 eyes (46.8%) and more than once in 25 eyes(53.2%). the mean number of lsl was 1.63±0.7. the mean iop before trabeculectomy was 30.2 mmhg and it was 24.1±6.3 mmhg (14-42 mmhg) before lsl. the mean interval time between trabeculectomy and performance of suture lysis was 7.9±6.3 days. the mean iops before and immediately after laser suture lysis were 24.15±6.93 mmhg and 17.47±5.81 mmhg respectively in patients that lsl was performed once (p<0.001). the mean iops before and immediately after laser suture lysis were 23.96±7 mmhg and 16.6±4.61 mmhg respectively in patients that lsl was performed more than once (p<0.001). the difference was statistically significant in two groups (p<0.001). at the last visit, the mean iop was 14.6±4.07 mmhg (4-25 mmhg) (p<0.001). the mean follow-up time was 21.4±20.01months (1-89 months). conclusion: laser suture lysis is a safe and effective method in the management of the patients in whom the target iop was not reached after trabeculectomy and it can be performed more than once.
