title: [Photocoagulation and scleral cryotherapy for Coat's disease].
abstract: OBJECTIVE
  To evaluate the results and significance of Coat's disease with argon laser photocoagulation and cryotherapy.
  
  
  METHODS
  22 patients (23 eyes) were treated by argon laser (German Opton Meditek 40 E, 0.2w power, 100-500 um spot, 0.1-0.2 second exposure and grade II reaction) and or scleral cryotherapy (-60 to approximately -80 degrees C, 5 second duration per time, repeating treatment if necessary until pale edema was seen in retina).
  
  
  RESULTS
  18 eyes in all (78.2%) had good results with visual acuity improvement and the lesion of fundus had been seen decreased in varient degrees. The follow-up ranged from 1 to 3 years.
  
  
  CONCLUSIONS
  Photocoagulation and scleral cryotherapy are effective for those patients with Coat's disease. It is very important to treat them promptly so as to prevent the damage of visual function progressively.
