The Effect of Flat Anterior Chamber on the Success of Ahmed Valve Implantation

ABSTRACT

PURPOSE: To evaluate the outcome following Ahmed valve implantation in patients who developed flat anterior chamber. METHODS: The authors reviewed 60 eyes of 60 patients who underwent Ahmed valve implantation and divided these patients into the flat anterior chamber group (18 eyes) and the control group (42 eyes). The influence of clinical variables on the development of flat anterior chamber and the effect of flat anterior chamber on the success of Ahmed valve implantation were evaluated. RESULTS: The preoperative intraocular pressure, age, and the incidence of neovascular glaucoma as a preoperative diagnosis were higher in the flat anterior chamber group than in the control group (p0.05). CONCLUSIONS: The development of a flat anterior chamber after Ahmed valve implantation appeared not to affect the outcome of the surgery.
