Uneven Pupils

Your dog or cat has one pupil that is visibly smaller than the other. Uneven pupils in pets, medically known as anisocoria, is a condition in which one pupil is visibly smaller than the other. This condition can affect both cats and dogs of any age or breed. Some of the most common health issues that can cause uneven pupils in dogs and cats include inflammation of the frontal region of the eye, excessive pressure within the eye, scar tissue, various medications and cancer.

Uneven Pupils

How to Recognize

Crouch to your pet\'s eye level and check their pupils to see if one pupil is larger than the other. It is a good idea to routinely check your pet\'s pupil size.

Causes

Inflammation, increased pressure, or built up scar tissue in the eye can cause pupils to become unequally sized. Diseases or tumors may also be the cause.

Diagnosis

Your veterinarian will use an Ultrasound to search for any possible trauma and an MRI or CT scan to look for a growth that could be the cause of uneven pupils.
