Overview

Strabismus is misalignment of the eyes, either medially (esotropia) or laterally (exotropia).
Strabismus is often quite subtle and difficult to detect; slight angulation of the head to either side may be a sign of compensation for a subtle strabismus.
  • Causes of Strabismus

  • Structural - intraocular or orbital mass
  • Ocular muscle weakness
  • Trauma
  • Neurological - oculomotor (III), trochlear (IV), abducens (VI) or upper motor neuron lesion
  • Fatigue / stress
