AIM: To analyze the common causes and treatments methods of high intraocular pressure(>21mmHg)after trabeculectomy.

METHODS: Twenty-four eyes of glaucoma patients with high intraocular pressure after trabeculectomy in our hospital from July 2010 to September 2014 were retrospectively studied. The common cause and processing methods were analyzed.

RESULTS: The causes which lead to early postoperative high intraocular pressure included high filtering bleb scar in 11 eyes(46%), filtration obstruction in 4 eyes(17%), malignant glaucoma 3 eyes(12%), iris resection of malignant glaucoma unreasonable 2 eyes(8%), hyphema 2 eyes(8%), wrap cystic filtering bleb 2 eyes(8%), etc. After proper treatments, intraocular pressures of all patients were bellowed 21mmHg.

CONCLUSION: High intraocular pressure with surgery for glaucoma is caused by multiple factors, preoperative and intraoperative avoid as far as possible, postoperative early detection for symptomatic treatment is the key to successful operation.
