Résumé
PURPOSE: To compare the surgical outcomes of repeat deep sclerectomy (DS) and the Baerveldt glaucoma implant (BGI) in eyes with failed primary deep sclerectomy. DESIGN: A retrospective comparative case-control study. METHODS: Fifty-eight eyes of 56 glaucoma patients with previously failed DS underwent BGI (group BGI) and 58 eyes of 55 patients underwent repeat DS (group DS) at a tertiary referral centre. Visual acuity, intraocular pressure (IOP), number of glaucoma medications, surgical failure rates and complication rates were compared between groups. Surgical failure was defined as loss of IOP control, loss of light perception, or need for further glaucoma surgery. RESULTS: Baseline demographics were similar between groups. Preoperatively, median IOP was lower in the DS than the BGI group (19 mmHg versus 21 mmHg, p = 0.10). Postoperatively at year 1, median IOP was significantly higher in the DS than BGI group (14 mmHg versus 11 mmHg, p = 0.02). There were no differences between the DS and BGI groups in mean number of medications preoperatively (2.3 versus 2.6) or postoperatively (1.3 versus 1.1). Complication rates were significantly higher in the DS group [41 % (n = 24) versus 14 % (n = 8); p = 0.01]. The failure rate at 1 year was higher in eyes with repeat DS than in eyes with BGI (30 vs. 21 %, respectively; p = 0.07). CONCLUSIONS: Baerveldt implants were more effective in lowering IOP and resulted in significantly fewer complications than repeat deep sclerectomy in eyes with previously failed deep sclerectomy.
