Constriction Of The Pupil

Constriction Of The Pupil

If your dog or cat has a reduced size of the eye pupil, or constriction of the pupil, it's possible it can be caused by a trauma to the eye or a systematic disease. Issues with the eye can have a great impact on your pet's vision, which is why you should never wait with taking action. It is advised to consult a veterinarian in case of constriction of the eye to determine the cause.

How to Recognize

If one or both pupils appear smaller than usual or do not dilate in the light, it can be a sign of an underlying issue.

Causes of Constriction Of The Pupil

Constriction of the pupil may be due to inflammation, increased pressure or built up scar tissue in the eye, cancer or a tumor, or an eye disease.


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 the constriction.

At these moments when your pet is ill or maybe needs surgery, you want to be protected for the unexpected and high veterinarian costs.
