title: Bilateral Coats' disease: long-term follow up.
abstract: OBJECTIVE
  To report on the long-term follow-up of a female patient with bilateral Coats' disease, who showed marked asymmetry between the two eyes.
  
  
  METHODS
  A five year old girl presented in 1978 with leukocoria in a blind right eye. A total exudative retinal detachment and extensive retinal telangiectasiae were noted. In the other eye, there was a localized area of retinal exudation and vascular abnormality in the supero-temporal periphery. Ultrasonography showed no evidence of intraocular tumour in the right eye and a clinical diagnosis of bilateral Coats' disease was made.
  
  
  RESULTS
  In 1995, the area or retinal exudation in the left eye increased and laser photocoagulation was applied successfully. To date, no disease recurrences have occurred.
  
  
  CONCLUSIONS
  Although Coats' disease is usually unilateral, bilateral, asymmetrical involvement may occur on rare occasions. Long-term follow-up of the least affected eye is necessary so that late complications can be identified early and treated adequately to prevent visual loss.
