DRY EYE DISEASE
Irritation can lead to:
Visual disturbances often appear as:
Fluctuating unstable visual acuity
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
In most patients, oil deficiency on the tear film causes a dry eye
because oil deficiency results in increased evaporation of the tear water
oil deficiency typically results from obstruction of the meibomian glands in the eyelids
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.
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
through many self-reinforcing vicious circles
Inflammatory reactions are an important factor in enhancing the disease
this requires timely and specific therapy by the cinician
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
