title: [Sudden blindness of 11-year old boy in the course of acute lymphoblastic leukemia].
abstract: OBJECTIVE
  The aim of this study is to present dramatic ocular manifestation of acute lymphoblastic leukemia.
  
  
  METHODS
  The 11 years old boy was hospitalized due to acute leukemia at the Department and Clinic of Pediatric Hematology, and was referred to ophthalmic examination because of sudden blindness of the right eye. General ophthalmic examination and electrophysiological tests were done.
  
  
  RESULTS
  No light perception of right eye, and markedly reduced visual evoked responses were caused by infiltration with great edema in optic nerve and its surrounding of retina. In spite of the fact, that the infiltrations disappeared after general therapy, the vision did not recover at all.
  
  
  CONCLUSIONS
  Even intensive treatment may be ineffective in blindness prevention in severe course of acute leukemia.
