INTERNATIONAL JOURNAL OF OPHTHALMOLOGY(2022)
摘要
AIM: To evaluate the efficacy and safety of modified trabeculectomy (experimental group) and implantation of EX-PRESS drainage device (control group), combined with intravitreal conbercept injection for neovascular glaucoma (NVG). METHODS: Totally 30 patients with NVG were selected from June 2014 to June 2017, and randomly divided into experimental group and control group. All patients were underwent intravitreal conbercept (0.5 mg/0.05 mL) treatment before surgery. Modified trabeculectomy was performed in MT group, while EX-PRESS drainage device implantation was performed in EX group. The success rates, best corrected visual acuity (BCVA), intraocular pressure (IOP), filtering bleb and complications were observed and compared. RESULTS: The differences of success rate, BCVA and filtering bleb were not statistically significant 12mo after the surgery (P>0.05), however, the difference of IOP at 1d, 1wk, 1, 3, and 6mo after surgery was statistically significant (F-time=390.6 4, P-time<0.0001) between two groups. The interactions between two groups in the given time showed no significant difference (F-intergroupxtime=0.181, P-intergroupxtime=0.57), and also there was no significant difference in IOP between the two groups (F=3.16, P=0.09). The results of pairwise comparison at each time point showed no significant difference in IOP between 1d and 1wk, 3 and 6, 3mo and 12mo after surgery (P>0.05), while the results at other time point indicate statistical differences (P<0.05). CONCLUSION: The modified trabeculectomy and the implantation of EX-PRESS drainage device have clinical application value in reducing IOP and postoperative complications of refractory NVG.
