title: Long-term results of Molteno implant insertion in cases of chronic angle closure glaucoma.
abstract: BACKGROUND
  This study was undertaken to provide data on the long-term results of cases of chronic angle closure glaucoma with additional risk factors treated by Molteno implants between 1985 and 2004 at Dunedin Hospital, New Zealand.
  
  
  METHODS
  A prospective non-comparative case series followed 21 eyes (17 patients) for a mean of 5.7 years (range 1.3-16.3 years) in terms of intraocular pressure, visual acuity and subsequent procedures.
  
  
  RESULTS
  Insertion of a Molteno implant has controlled the intraocular pressure at 21 mmHg or less in 100% of cases at 5 years after surgery, the probability of control being 0.95 (95% CI 0.91-0.99). The mean number of hypotensive medications reduced from 2.04 (SD 0.92) preoperatively to 1.40, 0.64 and 0.66 at 1, 2 and 5 years, respectively. The mean visual acuity improved from 6/18 preoperatively to 6/12 at 1 year and declined to 6/13.5 at 2 and 5 years.
  
  
  CONCLUSIONS
  Insertion of Molteno implants was a safe and effective procedure in the management of complex cases of chronic angle closure glaucoma.
