Baerveldt implant in refractory glaucoma: long-term results and factors influencing outcome
Roy S; Ravinet E; Mermoud AInternational Ophthalmology 2002; 24: 93-100
PURPOSE: To evaluate the clinical outcome of patients who received a Baerveldt implant for refractory glaucoma and to identify factors that may influence the outcome. METHOD: Retrospective study including 51 eyes of 51 patients with medically uncontrolled glaucoma who underwent Baerveldt implant surgery between June 1994 and December 1998. Criteria for success were intraocular pressure (IOP) ≤ 21 mmHg and > 6 mmHg, necessity of further antiglaucoma medications, absence of additional glaucoma surgery, and no loss of light perception. RESULTS: Over a mean follow-up of 37.6 (SD: ± 18.8) months, the mean intraocular pressure (IOP) decreased from 34.8 (± 12.5) to 14.0 (± 4.3) mmHg at month 60. Qualified success rate, achieved when IOP was below 21 mmHg and higher than 6 mmHg with medications, was 25/48 (52%), complete success rate (same IOP limits without medication) was 14/48 (29%). Seven eyes had major complications or lost light perception. Postoperative visual acuity improved or remained within one Snellen line of the preoperative visual acuity in 35 patients (73%). Factors associated with a better prognosis were a preoperative visual acuity better than 20/400 and etiology of glaucoma. CONCLUSIONS: The Baerveldt implant is effective in lowering IOP in most patients with refractory glaucoma. Long-term results are promising with satisfactory IOP control.
