Veterinary ophthalmology is a branch of pet medicine that focuses on eye care and ocular disease prevention. Annual pet vision exams evaluate current eye health, measuring tear production, eye pressure, and potential corneal scratches. If more serious issues are detected, such as glaucoma, cataracts, early vision loss, or dry eye problems, they will be addressed and treatment will be planned. During treatment planning, all options and recommendations will be thoroughly discussed so we can build an effective and comfortable vision procedure for you and your pet.
Indications of pet eye problems:
Abnormal growth near or on the eye.
Behavioral changes, namely a sense of depression.
Bumping into objects or seemingly lost in a familiar setting.
Discoloration of the iris or pupil.
Hazy film over pupil.
Increase in discharge from eyes.
Pawing and rubbing eyes.
Red, swollen eyes.
Sensitivity to light or squinting.
Preventing and improving pet vision problems
Various tests can be performed to help the veterinarian diagnose eye problems. Each vision test is cautious of pet comfort and does not cause pain. If serious problems are detected, treatment options, including surgery, will be discussed.
Fluorescein Stain – By inserting drops of a florescent green stain on the eye, the veterinarian will be able to detect secretion from any sores. The bright green stain rests in scratches and on wounds so the veterinarian can easily detect them.
Schirmer Tear Test – The veterinarian will place a small strip of test paper beneath your pet’s eyelid with the intention of irritating the surface of the eye. This irritation will cause the eye to water, allowing the vet to test the amount of tears produced per minute.
How does pet vision differ from human vision?
Pet vision is vastly different from human eyesight with the primary distinctions being visual acuity and color spectrum. Pets have fewer cones in their retina, limiting the amount of colors they can see. Because of this, pets can only distinguish between yellow, white, blue, violet, and black. Your pet also has a much wider field of vision than humans do, but their acuity is limited to a range of about 20 feet. The final difference is pets have an additional structure in their eye called a tapetum. This tapetum enables pets to have more accurate night vision by gathering light and increasing what is able to be seen.
