ABSTRACT

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. ● CONCLUSlON 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.
