Causes analysis of early postoperative high intraocular pressure of angle-closure glaucoma underwent compound trabeculectomy

AIM:To analyze the causes and treatments of high intraocular pressure(>21mmHg)of angle-closure glaucoma underwent compound trabeculectomy 1mo after surgery. METHODS:This was a retrospective study of our hospital, from March 2010 to March 2013. Thirty-four(38 eyes)of angle-closure glaucoma patients were collected, who underwent compound trabeculectomy with high intraocular pressure(>21mmHg)1mo after operation. We analyzed the causes and summarized the treatments. RESULTS:The causes which lead to early postoperative high intraocular pressure included malignant glaucoma(9 eyes of 8 cases), blood clot and connective tissue block under the scleral flap(15 eyes of 13 cases), hyphema after surgery(5 eyes of 5 cases), sclera flap incision was incarcerated with iris tissue(3 eyes of 3 cases), preoperative high intraocular pressure for a long time(5 eyes of 4 cases), 1 eye of 1 case for unknown reason. After proper treatments, intraocular pressures of all patients were bellowed 21mmHg. CONCLUSION:Early postoperative high intraocular pressure of angle-closure glaucoma underwent compound trabeculectomy is caused by various factors, and the early prevention and timely treatment are key points of a successful operation
