The Ahmed Glaucoma valve: a new implant for high intraocular pressure
Hille K; Ruprecht KWOphthalmologe 1999; 96 653-657
In incurable glaucoma the implantation of traditional drainage systems (such as the Molteno implant) usually leads to extreme hypotension in the eye in the first postoperative period. The Ahmed Glaucoma Valve presents an alternative method to avoid this problem. PATIENTS AND METHODS: Ten patients with incurable glaucoma received an Ahmed Glaucoma Valve. The average age was 59 years (22-81 years) and the follow-up period was an average of eight months (4-20 months). RESULTS: In the early postoperative period the average IOP was 5.5 mmHg (range, 4-8.5 mmHg). The authors noted choroidal detachments in two patients, but no shallow anterior chamber. In six patients the pressure rose over 22 mmHg, but they induced filtration by massaging the eye or rinsing the system in three and two patients, respectively. In nine of the ten patients, tension was definitively regulated, in one with an additional topical medication against glaucoma. CONCLUSIONS: Unlike the classic glaucoma drainage systems, the Ahmed Glaucoma Valve reduces intraocular pressure in the first postoperative period without the problems of excessive hypotension.
