AIM:To explore the clinical effect of the Ahmed glaucoma valve implantation for treetment of refractory glaucoma. ·METHODS:Totally 18 patients with refractory glaucoma underwent glaucoma surgery using Ahmed glaucoma valve.The changes of intraocular pressure,the vision and postoperative complications were observed. Follow-up time was from 3 to 12 months.·RESULTS:At the postoperative month 1,the intraocular pressure was changed from 51.53±6.57mmHg to 16.82±5.63mmHg,and the successful rate was 95%; at the postoperative month 3,the intraocular pressure was changed from 51.53±6.57mmHg to 17.14±6.38mmHg,and the successful rate was 89%; for those eyes with the follow-up ≥12 months(n=15),the intraocular pressure was changed from 50.36±7.92mmHg to 18.35±7.24mmHg,and the successful rate was 73%.·CONCLUSION:The glaucoma surgery using Ahmed glaucoma valve is an effective method for refractory glaucoma,and this is a simple operation,rapid recovery,fewer complications,better intraocular pressure and vision.
