A menace test may also be conducted to see if the pet blinks when a finger is moved toward, but without touching, the eye. A pupillary light reflex test is used to evaluate the retina the sensory membrane that lines the eyethe muscles controlling the iris the colored portion of the eyethe nerves, and the part of brain that controls visualization.

The veterinarian will shine a bright light into each eye and evaluate both eyes for pupil constriction. If the veterinarian is concerned about tear production, he or she may perform a Schirmer tear test. A small strip of paper is positioned in each lower eyelid and held in place for 60 seconds.

This test can help determine if your pet is producing enough tears to lubricate the eye properly. An ophthalmic exam usually includes a thorough evaluation of the outer eye structures, including the tissues around the eyes, the eyelids, the duct where the tears drain from the eyes, and the cranial nerves that affect the eyes.

The lens of the eye will also be examined for signs of cataracts. It is common for pets to inadvertently scratch the cornea the clear layer on the front of the eye. Because these painful abrasions or ulcers are not always visible with the naked eye, your veterinarian may conduct a fluorescein stain test.

Another painful condition for pets is glaucoma high eye pressure caused by improper fluid drainage within the eye. Certain breeds and some diseases, such as diabetesare associated with glaucoma.

Our primary test is the non-contact tonometer, which uses an air puff against your eyeball while you are staring at a light source.

Both tests are painless and having a glaucoma test is an important part of identifying potential eye issues at an early stage.

Perimetry Test If the doctor determines it necessary, he or she will perform a threshold perimetry or visual field test to check for blind spots in your peripheral vision.
