Abstract
|
|
|
Purpose: To compare the safety and efficacy of polypropylene and silicone Ahmed glaucoma valves (AGVs).
Methods: The medical records of 62 consecutive refractory glaucoma patients who had undergone AGV implantion from March 2003 to December 2005 were reviewed retrospectively. Among the 62 patients, 32 patients underwent polypropylene AGV implantation (group P) and the other 30 patients underwent silicone AGV implantation (group S). Postoperative IOP, the complication rate, and the success rate were compared between the two groups.
Results:The life-table success rates for the group P were 81.3% at 6 months and 71.2% at 12 months, and the success rates for the group S were 89.9% at 6 months and 78.6% at 12 months, showing no significant difference between the two groups. Complications, including non-tube-related complications, were observed more frequently in the group S, but there was no significant difference between the two groups.
Conclusions:The silicone AGV can reduce IOP effectively but may be associated with non-tube-related complications.
