The Comprehensive Dry Eye Examination: Everything You Need to Know

🔎The dry eye examination is comprehensive and involves several tests to determine the cause and severity of dry eye.

💧Tests for tear film osmolarity and tear quantity help assess the balance of the tear film and identify tear production issues.

🔍Meibography is used to examine the oil glands in the eyelids, which can become inflamed and affect tear stability.

🔬Inflammation plays a significant role in dry eye, and tests like the Inflammadry measure the presence of an inflammatory biomarker called mmp9.

⌚Corneal sensitivity testing with the Cochet-Bonnet test helps identify neurological communication issues and assess corneal healing.

What tests are included in a comprehensive dry eye examination?

—A comprehensive dry eye examination includes tests for tear film osmolarity, meibography, inflammation (Inflammadry), tear quantity, corneal sensitivity (Cochet-Bonnet test), and more.

Why is tear film osmolarity testing important?

—Tear film osmolarity testing measures the salt content of the tear film and helps evaluate tear stability. High osmolarity indicates a loss of balance and can indicate severe dry eye.

What is meibography?

—Meibography is an imaging test that scans the oil glands (meibomian glands) in the eyelids. It helps assess the quantity and quality of the oil produced and identifies any inflammation or blockages.

What does the Inflammadry test measure?

—The Inflammadry test measures the presence of an inflammatory biomarker called mmp9 in the tears. Its presence indicates the presence of inflammation, which is common in dry eye.

What is corneal sensitivity testing?

—Corneal sensitivity testing, such as the Cochet-Bonnet test, measures the sensitivity of the cornea to touch. It helps evaluate neurological communication and assess corneal healing in individuals with dry eye.
