yes we can ... Explain the symptoms  in dry eye disease easily and systematically

for the deficiency of the tear film     and for the irritation and tissue damage. Often, the symptoms are quite nonspecific, so the diagnosis can be difficult for both the patient and the doctor:



At first glance ...   The causes of a dry eye disease seem to be very different ...

...  but can be summarized  in Basic Causative Factors  and  Negative Influencing Risk Factors ... in order to shorten the story:

Basic Causative Factors   are

  • a lack of production of tears

    • Contrary to common wisdom ... a lack of water due to low production of aqueous tears by the lacrimal gland is only rarely the first cause of a dry eye

    • In most patients, oil deficiency on the tear film causes a dry eye

  • and... / or

  • a lack of film formation from the available tears  

    • The eyelid blink is of great importance for the spreading of the tears into the tear film on the ocular surface

      • to keep the surface moist and healthy

      • to allow perfect visual acuity

    • If the regular blink is disturbed, the ocular surface health is endangered and the vision becomes blurry. This happens

      • during concentrated visual work (eg screen work, driving a car, television) with rare blinking of the eyelids. In such conditions the tear film is not renewed sufficiently often - it ruptures and the tissue becomes dry.

      • during incomplete blinks / nervous blinking, the eyelids are not fully closed and thus the tear film is not completely renewed - the lower part of the cornea remains dry, which leads to tissue damage

Can you believe that ...  Many risk factors   have a harmful influence and favor dry eye, for example:

  • dehydrating influences (draft, wind, dry air, air conditioners, blowers)

  • Hormones (relative lack of male hormones and excess of female hormones)

    • this also applies to medications such as anti-androgens and estrogen replacement therapy

  • Aging processes with advancing age

  • Excessive cornification of the skin

  • Various medications can promote a dry eye

    • eg: beta-blockers for high blood pressure and anti-histamines for allergies

  • Many negative factors in office work can lead to the so-called " office eye ".

    • This describes concentrated visual work with a rare blinking in a dry air, e.g due to air conditioning, often with mental stress, perhaps with additional smoking, irregular drinking or with drinks that are more likely to lead to water loss, such as coffee and tea.


and then ... Dry Eye Disease tends to Get Worse without adequate treatment

Many things can be helpful in the treatment of Dry Eye Disease, e.g.:

  • avoid desiccating influences such as draft and blowers

  • maintain a sufficient drinking volume - this can already be a simple and effective preventive measure

  • regular complete eyelid blinks and short breaks, with blink exercises during concentrated visual work (computer screen, driving a car, etc.). In the Blink exercises, the eyes are vigorously closed and reopened several times to renew the tear film and force oil from the meibomian glands onto the eyelid margin and onto the tear film.

  • own treatment of the clogged meibomian glands in the eyelids by warming and eyelid massage

  • aqueous tear supplements and oil supplements, as drops or as liposomal spray

  • in severe cases also specific medications from the ophthalmologist, if it has already come to a chronic inflammation of the eyes
