title: Cyclophotocoagulation with the transscleral contact red 670-nm diode laser in the treatment of glaucoma.
abstract: OBJECTIVE
  To retrospectively evaluate the results of cyclophotocoagulation (CPC) with the transscleral contact red 670-nm diode laser in treating glaucoma.
  
  
  METHODS
  Cyclophotocoagulation was performed in 60 eyes of 60 patients with a mean age of 74 +/- 11 years (range 49-90 years). The treatment was delivered via a fibre-optic probe. The power per application was 430 mW. Exposure time was 10 seconds.
  
  
  RESULTS
  The mean overall follow-up time after the initial CPC was 26 +/- 20 months (range 3-75 months). Preoperative intraocular pressure (IOP) was 27 +/- 11 mmHg (n = 60). After one or more CPC treatments, mean IOP decreased to 20 +/- 7 mmHg (n = 51) at 1 month, 19 +/- 5 mmHg (n = 45) at 3 months, 18 +/- 5 mmHg (n = 29) at 6 months, 19 +/- 7 mmHg (n = 22) at 1 year, 18 +/- 7 mmHg (n = 16) at 2 years, 14 +/- 4 mmHg (n = 8) at 3 years, and 18 +/- 6 mmHg (n = 60) at the last follow-up. An IOP of 8-21 mmHg or a > 30% decrease in IOP was obtained in 33 of 41 eyes (80%) with baseline IOP > 21 mmHg at the last follow-up. Hypotonia (IOP < 8 mmHg) did not develop in any of the eyes studied.
  
  
  CONCLUSIONS
  Cyclophotocoagulation with the red 670-nm diode laser is an effective and well tolerated means of treating glaucoma.
