How Do Eye Doctors Identify and Treat Dry Eye Syndrome?

Dry eye syndrome, also known as keratoconjunctivitis sicca, is a condition that occurs when the eye's ability to produce enough tears is compromised. It can lead to dryness, redness, and discomfort in the eyes. It can also cause vision problems.

The tear film covering the eye's surface is essential for maintaining the health and comfort of the eye. It helps keep the eye's surface moist and helps protect the eye from dirt, dust, and other foreign substances. The eye can become dry and uncomfortable when the tear film is not functioning properly.

Identifying Dry Eye Syndrome

Schirmer's Test

Schirmer's test is a diagnostic test used to evaluate the production of tears in the eye. It is often used to diagnose dry eye syndrome and other tear-production conditions.

During Schirmer's test, a thin strip of filter paper is placed under the lower eyelid. The strip is left for a few minutes when the produced tears moisten the strip. The length of the strip's wet section is then calculated, and the results are used to assess tear production.

Tear Breakup Time Test

The tear breakup time (TBUT) test is a diagnostic test used to evaluate the stability of the tear film on the surface of the eye. It is often used to diagnose dry eye syndrome and other conditions that can affect the tear film.

During the TBUT test, a drop of fluorescein dye is placed in the eye. The dye stains the tear film, making it easier to see. The eye doctor will then use a special light to examine the eye, looking for fluorescence patterns on the eye's surface. The time it takes for the fluorescence to break up or disappear is measured, and the results are used to assess the stability of the tear film.

LipiScan

LipiScan is a diagnostic tool that uses interferometry to measure the thickness and composition of the tear film. It is a quick and noninvasive procedure that can be performed in a doctor's office.

During the LipiScan test, a small probe is placed on the eye's surface. The probe sends a light beam through the tear film onto the eye's surface. The light is then reflected through the tear film and onto a detector in the probe. The patterns of light reflected are analyzed to determine the thickness and composition of the tear film.

Treating Dry Eye Syndrome

LipiFlow®

LipiFlow® is a noninvasive treatment typically performed in a doctor's office. It is a treatment option for dry eye syndrome that uses thermal pulsation to unblock the meibomian glands in the eyelids. 

During the treatment, a device is placed over the eyelids. The device uses thermal energy and gentle massaging action to unblock the meibomian glands and stimulate the production of the oily layer of the tear film.

Eye Drops

Artificial tears: Artificial tears are eye drops made of a water-based composition, electrolytes, and other ingredients that mimic natural tears. 

Ocular lubricants are thicker eye drops designed to coat the eye's surface and provide longer-lasting relief from dryness. They work best for severe dry eye syndrome.
