Overview

Randomized trial validates screening tool for detecting visual problems in acute stroke care, suggesting improved patient outcomes.

Key Points

  • The aim is to validate the Norwegian version of the Vision Impairment Screening Assessment (VISA) against orthoptic examination and describe visual abnormalities in acute stroke patients.
  • Prospective observational study including 127 acute stroke patients at Oslo University Hospital.
  • All patients underwent comprehensive orthoptic examinations as a reference standard.
  • VISA was performed by trained stroke clinicians and diagnostic performance was evaluated.
  • VISA demonstrated high sensitivity (94.5%) for detecting post-stroke visual problems but low specificity (34.6%).
  • The orthoptic examination identified visual abnormalities in 70.1% of patients, mainly ocular motility disturbance (46.5%) and visual inattention (38.3%).
  • NIHSS visual items showed lower sensitivity (60.7%) and agreement (62.0%), missing one-third of abnormalities detected by the orthoptic examination.
