Standard tests

Dry eye is caused by multiple factors and its diagnosis can involve various different examinations, including the following standard tests:

questionnaire deq 5.psd

Questionnaire​

There are several questionnaires used to assess the severity of dry eye and its impact on patients’ quality of life, including DEQ-5 (Dry Eye Questionnaire), OSDI (Ocular Surface Disease Index) and SPEED (Standard Patient Evaluation of Eye Dryness).
Diagnostic en analyse clinique

Clinical analysis

It is important to assess the appearance of the skin (for rosacea, eczema, psoriasis, seborrhoeic dermatitis), the anatomy of the eyelids, the appearance of the eyelashes, and blinking frequency.
test schirmer secheresse oculaire

Schirmer’s test

This test measures the amount of tears in the eye using a strip of filter paper placed inside the lower eyelid. It is an invasive method, performed without local anaesthetic. The filter paper gradually soaks up the tears.

If the eye is not producing enough tears, the strip will have less than 10 mm of moisture after five minutes. The test is a quantitative analysis and primarily measures dryness caused by aqueous deficiency, as in Sjögren’s syndrome.
break up time secheresse oculaire

BUT (Break-Up Time)​

This test assesses the quality and stability of the tear film on the cornea. A drop of fluorescein is instilled into the patient’s eye. The patient must then stop blinking so that the clinician can measure how long it takes for the tear film—made visible by the fluorescein—to break up. The test is positive if the tear film breaks up after less than 10s.

This test generally points to a problem with the lipid layer linked to excessive tear evaporation.
