PURPOSE: To compare the IOP & VA outcomes, and surgical success & retinal complication rate of Ahmed valve to other devices including Krupin valve with disc, singleplate Molteno, & Baerveldt implant. METHODS : Records of 62 consecutive primary aqueous-shunt procedures on 59 patients performed from 6/93 to 12/95, with minimum follow-up of 6 months, were reviewed. Surgical success defined as (l)IOP of 21 mmHg or less & greater than SinmHg with or without medication, or 22mmHg without medication; with (2)IOP decreased by at least 20% from preop.IOP; and (3)no additional glaucoma surgery or potentially visually devastating complication. RESULTS : 17 cases of Ahmed valves, 23 Krupin valves with disc, 9 single-plate Molteno, & 13 Baerveldt implants were included. After correcting for baseline differences, rates of postop. hypotony & retinal complications differed significantly among different implants (p=0.043 & 0.05 respectively). Ahmed valve had significantly less postop. hypotony and retinal complications than Krupin valve with disc or Baerveldt implant (planned comparison with Bonferroni correction for multiple comparison). CONCLUSION: Ahmed valve is associated with a lower rate of postoperative hypotony & retinal complications.
