title: Delayed fellow eye involvement in acute retinal necrosis syndrome.
abstract: OBJECTIVE
  We studied a case of acute retinal necrosis in which a 30-year delay occurred between involvement of the first and fellow eyes. After systemic treatment with acyclovir and prednisolone, the fellow eye developed a retinal detachment requiring vitrectomy and silicone oil tamponade.
  
  
  CONCLUSIONS
  The fellow eye retained a useful Snellen acuity of 20/120. In a patient who has had acute retinal necrosis, any symptoms or signs in the fellow eye, even several decades later, should alert the examining physician to the possibility of delayed involvement of the fellow eye.
