ResumoObjective To provide data on the results of patients with nonneovascular juvenile glaucoma who had Molteno implant surgery in the province of Otago, New Zealand. Design Prospective noncomparative case series. Participants Fifty-five operations in 52 eyes of 45 patients with nonneovascular juvenile glaucoma who had Molteno implant surgery between the ages of 9 and 49 years from 1976 to 2003 at Dunedin Hospital and were observed for a mean of 12.2 years (range, 0.1–25). Intervention Insertion of a Molteno implant. Main Outcome Measures Intraocular pressure (IOP) and visual acuity (VA). Results Insertion of a Molteno implant controlled IOP at ≤21 mmHg with probabilities of 0.89 (95% confidence interval [CI], 0.81–0.97) at both 1 and 2 years and 0.85 (95% CI, 0.75–0.95), 0.78 (95% CI, 0.66–0.90), and 0.71 (95% CI, 0.58–0.85) at 5, 10, and 15 years, respectively. Mean VA was 20/100 preoperatively; improved to 20/60 at 1 year; and stabilized at 20/120 at 5, 10, and 15 years postoperatively. Twenty-nine eyes had their preoperative VA maintained or improved at final follow-up, and the VAs of 17 eyes deteriorated but were at least light perception at final follow-up. Conclusion The use of Molteno implants in cases of nonneovascular juvenile glaucoma controlled IOP with a probability of 0.71 15 years postoperatively, whereas 53% maintained or improved their vision from their preoperative VA at final follow-up.
