As a pet owner you’ll know eye disease is common in small animals. Our Ophthalmology team are kept busy treating conditions like cataracts, corneal ulcers, entropion (in-turning of the eyelids), dry eye, inflammation of the eye, glaucoma, tumours and retinal diseases. We love nothing more than seeing the joy for both pet and owner when a small animal’s vision is repaired or restored.
Complete Eye Checkup
Your pet’s eyes should be examined as part of a regular physical exam. However, more thorough testing is needed in the following circumstances: 1. There is an abnormal appearance to one or both eyes. 2. Your pet shows signs of pain, such as holding an eye closed, or rubbing at the eyes. 3. You suspect that your pet is experiencing changes in vision. 4. An eye injury has occurred.
Cataract Diagnosis & Treatment
A cataract is a condition when the normally clear lens becomes cloudy. To use another food analogy, think about an egg white. When you crack an egg, the egg whites are clear enough to read a paper through. However, when you cook the egg whites, they go from clear to opaque. This is similar to what happens when a cataract forms. The normally clear lens becomes opaque or cloudy.
Corneal Reconstructive Surgery
The most common cause is trauma. An ulcer may result from blunt trauma, such as a dog rubbing its eye on the carpet, or due to a laceration, such as a cat scratch or a contact with a sharp object. Another common cause is chemical burn of the cornea. This may happen when an irritating chemical or substance such as shampoo or drywall dust gets in the eye.
We are experienced and specialized in handling the eye surgeries with utmost care.
Glaucoma is a condition in which pressure is placed on the eye, causing inadequate fluid drainage in the eye. If the condition becomes chronic or persists without treatment, it will eventually cause permanent damage to the optic nerve, resulting in blindness.
Disease of the Optic Nerve in Dogs
Glaucoma is common in certain dog breeds that are genetically predisposed, such as samoyeds, cocker Spaniels, poodles, chow chows, and Siberians. Unfortunately, 40 percent of dogs affected by glaucoma will become blind in the affected eye within the first year, regardless of medical or surgical treatment.
Symptoms and Types
There are two main types of glaucoma: primary and secondary. Symptoms for sudden primary disease, due to the eye’s inability to drain through the filtration angles of the eye, are as follows:
High pressure within the eye
Blinking of the eye
The eyeball may recede back into the head
Redness of the blood vessels in the whites of eyes
Cloudy appearance at front of the eye
Dilated pupil – or pupil does not respond to light
Electro Retino Graph (ERG)
Electroretinography (ERG) is a electrophysiological technique which measures the retinal action potentials in response to light stimulation. In small animal practice, electroretinography is more useful than other diagnostic techniques for the assessment of retinal function.
