Feline Glaucoma

Maybeck Animal Hospital explains that the "shape and architecture" of a cat's eye is created and nourished by a clear fluid called aqueous humor. When the natural drain of aqueous humor is compromised, fluid pressure increases inside the eye, resulting in feline glaucoma.

  1. Types

    • In an article published on Pet Place.com, Dr. Jennifer Wesler indicated that glaucoma comes in two different forms: primary and secondary. Primary glaucoma is caused by genetic problems in drainage area of the eye. Secondary glaucoma is the resulting side effect of another eye disorder.

    Significance

    • Maybeck Animal Hospital reports that primary glaucoma is rare in cats. Feline glaucoma is normally the secondary result of an eye condition called uveitis, which is actual inflammation within the cat's eye.

    Symptoms

    • Keep an "eye" on your cat's eyes for signs of feline glaucoma.

      Both Pet Education.com and Vet Info.com indicate that the symptoms of feline glaucoma include a swollen eye, dilated pupils, pain, enlarged blood vessels in the whites of the eye, noticeable squinting, excessive tearing and the cat avoiding light.

    Diagnosis

    • Diagnostic tests, as reported by Dr. Wesler, include a complete physical examination and a comprehensive eye exam. Eye pressure measurements and an evaluation of drainage pathways, lens displacement, tumors and optic nerve damage are all part of the eye exam.

    Treatments

    • Medications that decrease eye fluid production are common treatments for feline glaucoma. As the glaucoma progresses, however, surgery may be required to replace damaged drainage ducts. In severe cases, the eye may be removed altogether, according to Maybeck Animal Hospital.

    Considerations

    • Avoid painful feline glaucoma with regular check-ups.

      Normal feline intraocular pressure is between 10 and 20mmHg. Feline glaucoma creates a pressure as high as 45 to 65mmHg. Consequently, Maybeck Animal Hospital reports that feline glaucoma is extremely painful; therefore, it is critical to take the cat to the vet if you suspect glaucoma.
