OcuRx DryVue DA-2

Fully supports 7 dry eye testing functions including NiBut, Lipid Layer Static, Gland Opening, TMH (Tear Meniscus Height), Meibography, Corneal Staining and Red Eye Measurement.

The DA-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. A complete analysis and evaluation is provided at the end of testing. Brings two slit lamp attachments that are compatible with all systems. Can be used handheld or with slit lamp.

1. 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 The NiBUT 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 photos over time.
2. 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.
3. Gland Opening - 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)
4. 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
   
5. 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.
6. Corneal Staining- Corneal staining is a non-invasive procedure that uses special eye drops to highlight areas of damage or dryness on the cornea, the clear front surface of the eye. By identifying these issues, optometrists can accurately diagnose and treat conditions like:
   • Dry Eye Syndrome: Pinpoint areas of dryness and inflammation.
   • Corneal Abrasions: Detect minor scratches or wounds.
   • Corneal Ulcers: Identify more serious infections or damage.         
     
     7. 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.
