Many tests may be performed to determine what is causing your dry eye symptoms. Your eye doctor will start with a comprehensive eye exam and look for early signs of Dry Eye Disease. If your signs and symptoms are consistent with Dry Eye Disease, your eye doctor will schedule a dry eye evaluation.
A dry eye evaluation consists of extensive ocular testing of the tear film and structures that produce the three parts of the tear layer.
The Oculus Keratograph is used to measure tear quality, tear stability, and oil gland structure. Your eye doctor will take multiple images with this equipment to help determine if treatment is needed.
Your eye doctor will also examine your tears and the ocular surface under a microscope called a Slit Lamp. A yellow and/or green drop called Fluroscein and Lissamine Green will be added to your tears. This procedure helps to test for inflammation.
Your eye doctor will also perform Meibomian Gland Evaluation by gently pressing your eyelid margin to check the quality and quantity of the oil from your oil glands.
After your eye doctor completes your dry eye evaluation, they will form a treatment plan to help maintain your tear health and improve your quality of living.
