title: [Coexistence of unilateral retinoblastoma and Leber-Coats's disease in contralateral eye-case report].
abstract: OBJECTIVE
  A case report of retinoblastoma and Leber-Coats' disease coexistence--two diseases which are very dangerous to the organ of vision.
  
  
  METHODS
  The paper presents a young patient who was sent to our Clinic at the age of 6 with very advanced unilateral retinoblastoma. He underwent enucleation of the eyeball as the initial treatment. Histopathological examination confirmed clinical diagnosis without infiltration of optic nerve or sclera. After 9 years of oncological observation there were characteristic changes for Leber's angiomatosis (temporo-inferior part of the retina) in another eye. Laserocoagulation of changes was performed twice.
  
  
  RESULTS
  During 14 years of observation there was no retinoblastoma recurrence. In the peripheral part of the retina in the only eye there is constant progression of vessel changes which are the sources of periodical preretinal bleeding. In the macular region there were extensive exudative changes which lifted the retina and caused the total secondary retinal detachment. Laser photocoagulation, cryopexy and steroid therapy were ineffective. Ultimately the patient's visual acuity at distance deteriorated to light perception.
