Symptoms of Glaucoma in a Cat

Glaucoma occurs when a fluid imbalance in the eye creates high pressure, damaging the optic nerve, and initiating vision loss in cats. It usually appears later in life, and is either genetic or spurred by other eye diseases. Glaucoma is painful and permanent, but you can look for signs of the disease in your pet, and take it to a veterinarian for treatment.

  1. Behavior Exhibiting Pain

    • Your cat may eat less, hide, be lethargic, or be irritable. Cats will also squint their eyes in pain.

    Changes in Eye Color

    • The front surface of the cat's eye (the cornea) may turn blue or white. The entire eye may redden.

    Dilated Pupil

    • The pupil may be dilated and will not constrict when exposed to light.

    Discharge From Eye

    • Tears or a greenish-yellow puss may discharge from the eye.

    Bulging Eye

    • The eye may appear to bulge out or grow larger in later stages of the disease.

    Vision Loss

    • Your cat will appear to have lost its vision or to have completely gone blind.
