NIBUT: After a blink, this test measures how long the tear film remains on the cornea and when it breaks up, which reflects the stability of the tear film.
Lipid layer: The color and structure of the lipid layer (colored fringes resembling an oil slick) allow for the assessment of the quality and thickness of the lipid layer.
Meniscus height: By measuring the height of the tear meniscus (tear at the edge of the eyelid), this test assesses the amount of water in the tears.
Conjunctival staining: This test uses specific dyes (such as fluorescein) to highlight areas where mucins are deficient in order to assess the tear film’s adherence to the eye.
Meibography: This test provides a quick overview of the shape of the Meibomian glands. Meibography allows for the assessment of gland loss, atrophy, and obstruction, as well as telangiectasias in the eyelids.
Meibum expression: Pinching the eyelids with a special forceps to extract obstructed meibum in order to assess its quality and fluidity.
Chalazion: Observation of inflammation of a Meibomian gland
Zoom: Close-up observation of small blood vessels present on the edge of the eyelids.
Zoom: Observation of eyelid inflammation
Zoom: Close-up observation of the presence of mites on the eyelid margins.
Blink analysis: This test quantifies the number of blinks and identifies incomplete blinks.
Corneal staining: This test uses specific dyes (such as fluorescein) to highlight areas where mucins are deficient in order to assess the tear film’s adherence to the eye.
Bulbar redness: Observation of redness in the white part of the eye, a sign of irritation or inflammation of the ocular surface.
Think you may have dry eye? Take two minutes to assess your symptoms using the OSDI-6 questionnaire (six questions) provided on our site.
New IPL (intense pulsed light) treatments—all completely painless—are now available alongside a range of other treatment options for dry eye. But how much do you know about this disease?
