title: Sonography of the optic nerve sheath beyond the hyperacute stage of intracerebral hemorrhage.
abstract: OBJECTIVE
  To evaluate the feasibility and utility of serial measuring of the optic nerve sheath diameter beyond the hyperacute and acute stage of intracerebral hemorrhage (ICH).
  
  
  METHODS
  Four patients with extensive ICH in the left basal ganglia were followed using ultrasound (US) and cerebral CT scans.
  
  
  RESULTS
  Optic nerve sheath diameter values assessed beyond the acute stage of ICH showed a high correlation (ρ = 0.84, p = 0.0022) with midline shift of the third ventricle seen on CT scans.
  
  
  CONCLUSIONS
  Optic nerve sonography can be useful to evaluate patients with extensive ICH beyond the acute stage and help monitoring clinical evolution in these patients, when ICP monitoring is not feasible.
