OcuRx Dry Eye Analyzer DEA-2

Fully supports 9 dry eye testing functions including NiBut, TBut, Lipid Layer Static, Lipid Layer Dynamic, Gland Opening, TMH (Tear Meniscus Height), Meibography, and Red Eye testing.

The DEA-2 is designed to be easy to use and to provide quick and accurate results. The entire dry eye examination can be completed in about five minutes.

1. TMH (Tear Meniscus Height):  Tear meniscus height (TMH) measures the height of the triangular-shaped area of tears at the junction of the lower eyelid and the cornea. TMH is a clinical measurement that can be used to help diagnose dry eye disease. 
2. NiBUT: Noninvasive tear break-up time (NIBUT) is a test that measures the stability of tear film to assess dry eye. It's a non-invasive method that doesn't require the use of dyes or fluids and is considered the preferred diagnostic test for tear film stability.
3. The TBUT is recorded as the number of seconds that elapse between the last blink and the appearance of the first dry spot in the tear film, as seen in this progression of these slit lamps photos over time. A TBUT under 10 seconds is considered abnormal.
4. Lipid Layer Static: Lipid layer static measurement refers to the evaluation of the lipid layer's thickness, structure, or stability on the surface of the tear film in the eye.
5. Lipid Layer Dynamic: Lipid layer dynamic measurement refers to the assessment of the behavior and performance of the lipid layer on the tear film during various activities, such as blinking or tear distribution over time. Unlike static measurements, which assess the tear film at rest, dynamic measurements focus on how the lipid layer responds and changes in real time, especially in response to natural actions like blinking and evaporation.
6. Meibomian gland opening measurement refers to assessing the orifices or ducts of the meibomian glands, which are located along the edges of the eyelids. Measuring the state of the gland openings helps in diagnosing conditions like meibomian gland dysfunction (MGD), which is a leading cause of evaporative dry eye.
7. Tear Meniscus Height (TMH) measurement refers to evaluating the height of the tear meniscus, the thin strip of tear fluid that forms at the junction between the eyeball and the eyelids. This measurement is commonly used to assess tear volume and is an important diagnostic tool for evaluating conditions such as dry eye disease and ocular surface disorders.
8. Meibography: Meibography is an imaging technique used to visualize and evaluate the structure of the meibomian glands, which secrete oils (meibum) that form the lipid layer of the tear film. This test is particularly important in diagnosing meibomian gland dysfunction (MGD), one of the leading causes of evaporative dry eye disease.
9. Red Eye Measurement: Red eye measurement refers to the assessment of the severity, extent, and underlying causes of ocular redness, which is often a sign of inflammation or irritation in the eye. Redness in the eye occurs when blood vessels on the surface of the eye (particularly in the conjunctiva or sclera) become dilated due to a variety of factors, including infection, allergies, dry eye, trauma, or other eye conditions.
