NYSTAGMUS

Regular and rhythmic to and fro involuntary

oscillatory movements of the eye

Occurs due to disturbance of the factors

responsible for maintaining normal ocular

posture.These include disorders of sensory

visual pathways,semicircular canals,vestibular

apparatus,mid brain and cerebellum

SQUINT

Medical terminology: strabismus

Condition where the eyes do not look in the same direction

MAY BE CONCOMITANT OR PARALYTIC

AMOUNT OF

DEVIATION IN THE

SQUINTING EYES

REMAINS CONSTANT IN

ALL DIRECTIONS OF
