Eye Examinations for Pets: When, How, and Why It Matters

Prof. Dr. Murat ŞaroğluUpdated on May 14, 2026

Most eye diseases share a common feature: they show no symptoms in the early stages. By the time the owner notices, the disease has usually progressed. That is why regular eye examinations are the most effective way to protect your companion's vision. So how often, under what circumstances, and exactly what is done during an examination?

Why regular eye examinations?

Many problems such as cataracts, glaucoma, and retinal diseases are managed much more effectively in the early stages. Waiting until symptoms appear is, in most cases, waiting too long. Regular check-ups catch problems before you notice them.

How often should they be performed?

  • In healthy adult cats and dogs, at least once a year
  • In older animals (over 7 years), every six months
  • More frequently in brachycephalic breeds
  • Regularly in breeds with a hereditary risk of eye disease
  • Regularly and without fail in diabetic dogs

Which symptoms require an examination without delay?

  • Tearing, redness, or discharge
  • Cloudiness or color change in the pupil
  • Squinting, sensitivity to light
  • Bumping into objects, decreased vision
  • Swelling or itching around the eye

What is done during an eye examination?

A comprehensive examination begins with the patient's history and proceeds systematically: vision and reflex evaluation, tear measurement with the Schirmer test, corneal assessment with fluorescein staining, intraocular pressure with tonometry, and finally examination of the front and back segments of the eye. These tests are simple, fast, and painless. For details on the process, you can visit our eye examination service page.

What difference does early diagnosis make?

A glaucoma caught early can be controlled with medical treatment, while delayed glaucoma can result in permanent blindness. The same applies to cataracts and corneal diseases. Early diagnosis is often the only factor that saves vision.

Frequently Asked Questions

My dog looks healthy — does it still need an eye examination?

Yes. Most eye diseases progress silently and symptoms appear late. An annual routine check-up catches problems early and preserves vision.

Does an eye examination hurt?

No. The tests used (Schirmer tear test, fluorescein staining, tonometry) are simple, fast, and painless.

My older dog's eyes are turning gray — is an examination really necessary?

The graying may be age-related nuclear sclerosis, which usually does not affect vision. However, it looks similar to a cataract; only an examination can distinguish the two, so a check-up is recommended.

Which breeds require more frequent check-ups?

Brachycephalic breeds, breeds with hereditary eye disease risk, and diabetic dogs should be checked more frequently.
