METHODS: Totally 47 patients(47 eyes)of NVG with cataract were given intraocular injection of anti-VEGF before the surgery, and then treated with Ahmed valve implantation. 19 cases(19 eyes)combined with phacoemulsification, and single Ahmed valve implantation in 28 cases(28 eyes). The vision, IOP, anti-glaucoma medicines and complications of the two groups were recorded and compared with 6mo postoperatively.

RESULTS:The IOP of all cases at all time points after surgery was significantly decreased after surgery(P <0.05). 6mo after surgery, in the combined group, the vision was improved in 10 cases(10 eyes)(53%), unchanged in 8 cases(8 eyes)(42%)and decreased in 1 case(1 eye)(5%). The complete success rate was 84%(16/19), the conditional success rate was 11%(2/19), and the failure rate was 5%(1/19). In the single Ahmed valve group, the vision was improved in 11 cases(11 eyes)(39%), unchanged in 17 cases(17 eyes)(61%), decreased in 0 case(0 eye)(0%), complete success rate in operation was 61%(17/28), conditional success rate was 25%(7/28), and the failure rate was 14%(4/28).

CONCLUSION: Compare with anti-VEGF with Ahmed vlave implantation, combined with phacoemulsification can effectively control the postoperative IOP, improve the BCVA of the patient as much as possible, reduce the amount of the postoperative glaucoma medicament use, and facilitate the follow-up of the fundus of the patient. It is a efficacy treatment for NVG with cataract.
