Sequential treatment of neovascular glaucoma with cataract by Conbercept intraocular injection combined with Ahmed valve implantation and phacoemulsification

Abstract

AIM: To investigate the therapeutic effect of conbercept injection combined with Ahmed valve implantation and phacoemulsification in the treatment of neovascular glaucoma(NVG).METHODS: Retrospective analysis. Totally 18 patients(18 eyes)with NVG complicated combined with cataract in our hospital from June 2018 to January 2020. All patients received intraocular injection of conbercept at 3-7d before surgery, Ahmed valve implantation and phacoemulsification were performed after meeting the surgical indications. Best corrected visual acuity(BCVA), intraocular pressure(IOP), resolution of iris neovascularization and postoperative complications were followed up after the surgery, and all the cases were followed up 12mo. RESULTS: Compared with preoperation(51.44±8.18 mmHg), IOP was significant decreased at 1, 7d, 1, 3, 6mo, 1a after surgery(25.94±11.82, 15.39±4.97, 15.94±2.69, 15.33±4.54, 18.89±7.95, 16.27±5.22 mmHg)(P<0.05). Last follow up after surgery, BCVA was improved in 12 eyes(67%), unchanged in 5 eyes(28%)and decreased in one eye. At 1a after operation, the complete success rate was 83%(15 eyes), conditional success rate was 11%(2 eyes), one eye of losing control of IOP was failed. CONCLUSION: Conbercept intraocular injection combined with Ahmed valve implantation and phacoemulsification can not only effectively control postoperative IOP, but also improve the visual acuity of the patients as much as possible. It is an effective method for the treatment of NVG with cataract.
