AIM: To make a retrospective analysis of the clinical data of modified trabeculectomy in treating glaucoma surgery with high elevated intraocular pressure retrospectively and evaluate the effect of modified trabeculectomy.<p>METHODS:One hundred acute angle-closure glaucoma patients(100 eyes)with persistent high intraocular pressure were divided into treatment group(45 eyes)and control group(55 eyes). Patients in treatment group was treated with by trabeculectomy, while those in control group received modified trabeculectomy. The modified measures include stellate ganglion block preoperative, topical anesthesia and local anesthesia with 20g/L lidocaine cotton-piece, to make scleral flap with sclerotome, to release aqueous humor outflow slowly after paracentesis of anterior chamber, and using mydriatic and cycloplegic during and after surgery.<p>RESULTS: The incidence of operation complicationin control group was lower than that in treatment group. The differences were statistically significant(<i>P</i><0.05). The intraocular pressure of control group was lower than that of treatment group after 3 months follow-up. The differences were statistically significant(<i>t</i>=9.1535, <i>P</i><0.05). The average hospitalization days and the expenses in the hospital of the control group were lower than that of the treatment group. The differences were statistically significant(<i>t</i>=39.8010, <i>P</i><0.01; <i>t</i>=11.3219, <i>P</i><0.01).<p>CONCLUSION: The modified trabeculectomy applied in the treatment of glaucoma with persistent high intraocular pressure can not only save the visual function of connection part to a certain extent, but also reduce the incidence of serious complications. It can obtain better intraocular pressure, shorten the average hospitalization days, decrease the expenses and increase patients satisfaction.
