title: Ten years follow-up after deep sclerectomy with collagen implant.
abstract: OBJECTIVE
  To evaluate the long-term success rate and complications of nonpenetrating deep sclerectomy with collagen implant in open-angle glaucoma.
  
  
  METHODS
  Clinical, prospective, monocentric, nonrandomized, unmasked study on 105 patients with medically uncontrolled glaucoma. A standard procedure deep sclerectomy with collagen implant was performed. Complete examinations were performed before surgery and postoperatively at 1 and 7 days; 1, 2, 3, 6, 9, and 12 months and then every 6 months during the 10 following years.
  
  
  RESULTS
  The mean follow-up was 101.5+/-43.1 (3 to 144) months [mean+/-SD, (range)]. The preoperative intraocular pressure (IOP) was 26.8+/-7.7 (14 to 52) mm Hg and the best-corrected visual acuity 0.71+/-0.33 (0.02 to 1.5). Ten years after surgery IOP was 12.2+/-4.7 (6 to 20) mm Hg and best-corrected visual acuity 0.63+/-0.34 (0.01 to 1.2) (number of remaining patients=52). The mean number of medications per patient went from 2.3+/-0.7 (1 to 4) down to 1.3+/-1.1 (0 to 3). An IOP <or=21 mm Hg without medication was achieved in 47.7% patients and in 89% with or without treatment. One major complication was reported. Goniopuncture was performed in 61 eyes (59.8%), 5-fluorouracil treatment given to 25 patients postoperatively and included needling (n=5).
  
  
  CONCLUSIONS
  On the basis of a 10-year follow-up deep sclerectomy with collagen implant demonstrated its efficacy in controlling IOP with few postoperative complications.
