Abstract:
We studied retrospectively the results of the Ahmed glaucoma valve implant surgery in 20 eyes with neovascular glaucoma. All cases were failed with medical or surgical glaucoma interventions. Mean follow-up period was 15.1 +/-14.9 months (3~56 months). The criteria for success included a postoperative intraocular pressure (IOP) of less than or equal to 21 mmHg and greater than or equal to 6 mmHg, and no additional glaucoma therapy or devastating visual complications. Mean IOP was significantly reduced from pre- operative 36.9 +/-5.2 mmHg to 17.6 +/-8.7 mmHg at the last visit. In respect with IOP control,success rate was 80%at final follow-up.The causes of failure were loss of light perception in 3 eyes (25%), inadequate IOP control in 2 eyes (10%), tube removal due to malfunction in 1 eye (5%). Complete success rate was 70%at a final follow-up.Complication included hyphema in 15 eyes,hypotony in 7 eyes, fibrous membrane formation and anterior synechiae in 3 eyes, tube obstruction in 2 eyes, flat anterior chamber in 1 eye, corneal decompensation in 1 eye, tube malposition in 1 eye, temporary choroidal detachment in 1 eye. These results indicate that Ahmed glaucoma valve implant for neovascular glaucoma can be a good successful IOP control device and comparable to the other drainage device.
