Text

Objective

The Ahmed glaucoma device is a valve equipped glaucoma drainage system for the treatment of complicated glaucomas. Their use in Germany is very limited.

Methods

From 1999 up to 2004 we implanted 12 such valves in 11 patients and retrospectively followed their outcome for consecutive 25 months. In most cases complicated secondary glaucomas with numerous preoperative procedures (5.3/patient) were treated. The mean age was 44.9 (19-84 years).

Results

Sucessful implantation was defined based on pre- and postoperative intraocular pressure (IOP). Before implantation IOP was 34 mmHg (24-45) and could be lowered to 16.0 mmHg (4-30mmHg). Visual acuity increased or stabilised in 8 of 12 eyes. Preoperative medications (2.6 / patient) was reduced to 1.0 per patient. The implantatation itself was without complications, postoperatively reversible hypotonie (6x), choroidal detachment (9x) and hyphema (3x) were observed. The rate of postoperative hypotonies appear to be less with the Ahmed valve compared to other glaucoma drainage systems.

Conclusions

The Ahmed valve appears to be a sucessful operative procedure to lower IOP longterm in complicated glaucomas.
