Eyes water for a number of reasons that may be divided up as follows:
- Too much tear production
- Impaired tear drainage
Impaired drainage may be due to laxity of the lower lid (so that it fails to form a proper gutter for tear drainage) or blockage of the tear duct system. Given that you are probably too young to have lid laxity and your tear ducts have already been checked, we have to look at tear over production.
Overproduction is usually due to continued irritation
of the surface of the eye. This can be due to infection, inflammation, allergy etc.
However, your post describes perfectly the condition known as 'mucus-fishing syndrome
This term is given to a vicious cycle in which the patient habitually removes mucus strands from the conjunctiva. This traumatises and stimulates the conjunctiva to produce more mucus (mucus productions is the eye's normal response to any irritative injury). Since more mucus is produced, the patient perpetuates the vicious cycle by fishing out this mucus, and stimulating the eye to produce even more.
The effective way to break the cycle is simply to stop extracting the mucus strands. If you must remove any excess mucus, you must do so without
touching any part of the surface of the eye. If mucus has become externalised on the skin, it may be removed very gently by wiping away with a clean tissue with the eyes closed
Another strategy that can help to break the cycle is N-acetyl-cysteine
eye drops (marketed in some places as i-lube
). Used upto three times per day, this can help dissolve mucus so that it doesn't form tenacious strands. However, the key to the whole thing is to abstain
from manually extracting the mucus from the conjunctiva.
