RESUMO
@#AIM: To investigate the effect of compound trabeculectomy in patients with primary acute angle closure glaucoma under persistent high intraocular pressure. <p>METHODS: From February 2015 to February 2016, we selected 62 cases(62 eyes)of primary acute angle closure glaucoma in our hospital, the control group 34 patients 34 eyes(preoperative intraocular pressure control in the normal range, intraocular pressure ≤ 21mmHg), the observation group 28 patients 28 eyes(preoperative intraocular pressure not in the normal range, the intraocular pressure 28-50mmHg and lasted for more than 3d). The two groups were treated with compound trabeculectomy and observed for visual acuity, intraocular pressure and so on. <p>RESULTS: Compared with preoperative, at 3mo postoperatively visual acuity improved, unchanged and decreased rate in observation group were 68%, 21% and 11%, the difference were not statistically significant compared with the control group(<i>P</i>>0.05). The postoperative intraocular pressure of the two groups compared with preoperative significantly decreased(<i>P</i><0.05). The postoperative intraocular pressure of observation group and control group were 11.10±2.20mmHg and 11.73±2.71mmHg, the difference was not statistically significant(<i>P</i>>0.05). The preoperative and postoperative anterior chamber depth of observation group was lower than that in the control group(<i>P</i><0.05). The postoperative anterior chamber depth of the two groups compared with preoperative increased(<i>P</i><0.05). The postoperative axial length of the two groups compared with preoperative decreased(<i>P</i><0.05). The postoperative complication rate of observation group was 14%, and the control group was 18%, the difference was not statistically significant(<i>P</i>>0.05). <p>CONCLUSION: Compound trabeculectomy in patients with primary acute angle closure glaucoma under high intraocular pressure is effective, but there still needs further study.
