. . . that makes everything easier to understand ... for everybody
GRITTY EYES - DRY EYES - WATERING EYES - ITCHY EYES - EYE REDNESS - OBSTRUCTED GLANDS - TIRED EYES - HEAVY LIDS - BLURRED VISION - UNSTABLE VISUAL ACUITY ... AND MANY MORE ..
All these different and partly contradictory appearing complaints ... can be symptoms of an Eye Irritation that occurs due to a Damage of the Ocular Surface Tissue
This happens typically following a Deficiency of the Tear Film in front of the eye. It can then no longer keep the delicate tissue sufficiently moist ... with the consequence that the Tissue dries out - This is the reason behind the term "DRY EYE"
The so-called ´DRY´ EYE DISEASE is a very wide-spread condition ... and it represents the most frequent diagnosis in clinical practice.
In contrast to the term "Dry" the occurring irritation of the ocular surface tissue may also lead to episodes of excessive tearing and watering eyes. This occurs particularly in the initial stage of this condition and is often difficult to understand for the patient.
DOCTOR, MY EYES ARE WATERY ... HOW CAN THAT BE ´DRY´ EYE DISEASE ???
An increased tear flow in case of watering eyes can indicate a (still) intact protective tearing reflex.
This reflex is generally triggered by irritation of many kinds such as e.g. wind and fans, or foreign bodies etc.
Such irritating incidences make the tears flow to remove the stimulus.
When the damage to the ocular surface proceeds, this protective reflex will unluckily also become dysfunctional and disappears.
Another reason for watering eyes with tear overflow over the eyelid border, medically termed as ´epiphora´, can occur due to eyelid deformations. Because eyes with eyelid deformations cannot form a normal tear film or cannot hold it on the ocular surface these conditions also lead to Dry Eye Disease with ocular irritation.
Frequent eyelid deformations are e.g. an inward or outward twist of the eyelid margin (ectropion or entropion) that typically occurs with tissue changes in advancing age.
DRY EYE DISEASE can be a ´tricky´ condition of the Ocular Surface
These few contemplations already indicate, that the so-called ´DRY EYE´ Disease can be an unexpectedly tricky issue.
´Tricky´ is not only the fact, that an eye in ´Dry Eye Disease´ can be watering.
Tricky is also the fact that... surprisingly ... most patients with ´Dry´ Eye Disease do not have a primary lack of water but they have a primary lack of oil in the tear film.
The oil on the surface of the tear film has the function to slow down the evaporation of tear water ... similar to a lid on a pot with warm water.
The healthy function of the Ocular Surface depends on a large number of factors that are inter-related and inter-dependent.
The functional and structural network at the Ocular Surface may probably be compared to a house of cards - it appears stable ... but as soon as only one card is moved ...
Science is working on the resolution of ocular surface disease - of which Dry Eye Disease is the most frequent one - for quite a while ... and researchers world-wide have made considerable advancements of knowledge.
This has translated into benefit for the daily lives of hundreds of millions of patients world-wide who suffer from Dry Eye Disease .
But even deeper insight into the disease process and thus continued scientific advancements are necessary to offer more effective strategies for therapy in the future.
IMPORTANT for the patient is to UNDERSTAND his/her CONDITION ... in order to understand the many ways to influence the condition in a beneficial way.
