title: Cortical blindness after complicated general anesthesia in urological surgery.
abstract: METHODS
  Male, 4 FINAL DIAGNOSIS: Cortical blindness after complicated general anesthesia Symptoms: Blindness • fine motor activity derangements
  
  
  METHODS
  - Clinical Procedure: General anesthesia for unilateral inguinal hydrocelectomy Specialty: Anesthesiology.
  
  
  OBJECTIVE
  Rare disease.
  
  
  BACKGROUND
  We report a case of transient cortical blindness after urological surgery.
  
  
  METHODS
  We present the case of a 4-year-old boy with visual loss following complicated general anesthesia during urological surgery. The results of ophthalmological examinations were normal. The complication was diagnosed as cortical blindness after obtaining an extinguished flash visual-evoked potential (flash VEP). The visual acuity persisted to be hand motion after 4 months.
  
  
  CONCLUSIONS
  We report a very rare case of cortical blindness after urological surgery. Unrecognized causes of cortical blindness are common in the children. Because of the long survival and increasing surgical management in this age group, it is of great importance and perhaps it will be necessary to alert parents about it. Anesthesiologists have a unique opportunity to facilitate positive outcomes for these patients through risk identification and appropriate management.
