Glaucoma or Disease of the Optic Nerve in Felines

Glaucoma is a health condition wherein high pressure happens in the eye, with the crash of normal fluid drainage. A serious condition with pressure against optic nerve will soon cause long term damage to the optic nerve, leading to blindness.

Types and Symptoms of Glaucoma

There are two major kinds of glaucoma, primary stage, and secondary stage. Sign for primary disease, because of the inability of the eye to drain in the filtration angles of the eye takes account of the following:

  • Eye blinking
  • Higher pressure in the eye
  • Eyeball might recede into the head
  • Blood vessels redness in the white of the eye
  • Cloudy look at the front of the eyes
  • Dilated pupil- doesn’t react to light
  • Loss of vision

Long term, advanced illness:

  • Swelling of the eyeball
  • Obvious vision loss
  • Advanced degeneration in the eye

Signs for Secondary Stage or Glaucoma Because of Eye Infections

  • High pressure in the eye
  • Blood vessels redness in the white portion of the eye
  • Cloudy look at the front of the eyes
  • Inflammatory debris noticeable in the front of the eye
  • Pupil constriction
  • Iris sticking to either the lens or cornea
  • Possible which the edge of the iris sticks to the lens circularly

What is more, there might be:

  • Anorexia or loss of appetite
  • Headaches, head pressing to ease sensations of pressure in the head
  • Change in outlook, less desire to interact and play

What Are the Causes?

High pressure within the eye happens once the normal depletion of fluid within the eye is impaired because of a primary disease like the improper growth of the filtration angles, or secondary to other diseases like primary lens, swelling of the tissue, eye tumor as well as blood clot in the front of the eyes from injury. In felines, the secondary stage is common compared to the primary stage of glaucoma. 

Diagnosis

You’ll need to provide a detailed background of your feline’s wellbeing, the start of the signs, as far as you can tell, and likely incidents which have preceded this illness, like eye injuries.

During the physical test, your vet will examine the pressure in your feline’s eyes utilizing a tonometer. Once the disease started suddenly, your vet will refer your feline to a veterinary ophthalmologist for a thorough test of both eyes, which include assessment of the filtration angles through gonioscopy – which measure eye’s interior. Pressure in the eye can measure as high as forty-five to sixty-five mmHg, which makes this an excruciating condition.

 An Electroretinography can be done by your vet ophthalmologist to know if the eye will stay blind in spite of treatment. In the secondary stage, X-rays, as well as ultrasound, might show abnormalities in the eye. Frequently both eyes are infected by glaucoma, but not always. In conditions where just one eye has this disease, steps will be taken to keep the unaffected eye safe from this disease.

Proper Treatment

Your vet will prescribe cat medication to lessen the pressure in his eyes and at the same time to back to the usual range as fast as possible.  If the condition is serious, surgery is highly recommended.
