Why are the whites of my dogs eyes red

If you notice redness in one or both eyes of your pet, you should visit your veterinarian to obtain a proper diagnosis. The most common causes of red eye are conjunctivitis, allergies, or irritants, however more serious possibilities exist so it is important to have your pet examined. The veterinarian will take a history of the pet to discover when the redness began, the progression of the redness, and any behaviors your pet is demonstrating that indicate pain or irritation.

Ophthalmologic Exam

In cases involving the eye, the veterinarian will conduct a full ophthalmologic exam. This exam evaluates the various structures of the eye including the conjunctiva, cornea, tear ducts, retina and eyelids.

Schirmer Tear Test

A Schirmer tear test examines your pet’s tear production and helps rule out KCS or dry-eye syndrome. This test involves placing a small paper test strip in between the eyelid and the eye. The strip measures tear production. The tears are absorbed into the paper strips and a scale on the paper measures the level of tear production.

Tonometry

Tonometry incorporates the use of a device to measure the internal pressure of the eye. This test is often used to screen for glaucoma, a disease associated with abnormal eye globe pressure. The surface of the eye may be numbed prior to this test, though it is not required. A tonometer pen uses a small plastic ball that bounces quickly on and off the surface of the eye and measures the pressure. Several measurements may be taken to obtain an average.

Fluorescein Dye

This yellow-green dye is dropped onto the eye surface. Areas of damage to the surface of the eye light up (fluoresce) when a black light is shone onto the eye. This dye can indicate scratches and corneal ulcers.

Blood Diagnostics

Several underlying issues may cause the appearance of red eyes. Blood screening can measure kidney function, liver function, hormone production, hydration and electrolyte imbalances.
