Centers in the brain stem control eyeball position through a reflex. Normal eyeball positioning requires normal functioning of several parts of the brain, the nerves that convey impulses between the brain and the eye, and the muscles that move the eyeball. “Eyeballs pointing in different directions” implies a problem in one of these anatomic areas.

This is a rare finding in adult horses, but much more common in foals. It can be seen in normal young foals and usually resolves over time. But it can also be a sign of damage or diseases that affect the brain and cranial nerve that control eye position.

Keep in mind that horses with different pigmentation around the eyeball (different whites of the eyes) can appear as though their eyes are pointing in different directions.

WHAT TO DO

Assess your horse’s general health using the Whole Horse Exam (WHE), and look for other signs of illness or disease. Pay particular attention the nervous system and compare one eye to the other. Assess your horse’s eyes, and perform the menace response to roughly assess your horse’s vision and reflexes.

Pay particular attention to attitude and appetite and normal movement, especially over obstacles like poles. Contact your vet with your findings and concerns.

WHAT YOUR VET DOES

Your vet performs physical and neurologic examinations in order to better understand the source of the problem and determine whether other diagnostics are necessary.
