Introduction

  • Signs: deviation of the globe from the proper axis for a given species.

Pathogenesis

Pathophysiology

  • Strabismus is a deviation of the globe.
  • The primary lesion in congenital forms is thought to be at the level of the cranial nerve nuclei.
  • Abnormal eye position and movement is also seen in cases of congenital blindness (central and peripheral) - this is not a permanent strabismus.
  • Acquired eye deviations are usually secondary to other neurologic diseases especially vestibular syndromes and will resolve with improvement in the primary condition.
