Strabismus
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
