Introduction
To assess clinical outcomes of the Ahmed glaucoma valve implant in patients with refractory glaucoma. Material and methods Participants: 15 patients (16 eyes), including 7 women and 8 men; patients with glaucoma: phakic – 10 eyes, pseudophakic – 4 eyes, and aphakic – 2 eyes, average age: 47.2 (18-72 years old), average IOP before the intervention: 47 mmHg (32-71 mmHg), average number of medications taken before the intervention: 3.0. Main Outcome Measures: Success was defined as IOP less than or equal to 21 mmHg and no need to perform another surgical intervention. Average period of observation was 23.2 months (6-42 months). Results Intervention was successful in 12 out of 16 eyes. Average number of medicaments taken after the intervention decreased to 1.2. 4 out of 16 patients had a hypertensive phase. Cumulative probabilities of success at 1 and 2 years were 88% and 72% respectively. Complications: hyphema – 4 eyes (25%), tube exposure – 1 eye (6.25%), corneal graft failure – 4 eyes (25%), hypertensive phase – 4 eyes (25%) anterior chamber shallowing – 2 eyes (12.5%) Conclusions The Ahmed glaucoma valve implant is an effective way of treating the patients with refractory glaucoma. keywords:
