Excessive tearing of the eyes is not necessarily straightforward. There are several potential reasons why this may be happening. The first place we usually look is within the tear film itself.
The eyes are always producing tears. The fluid comes from the lacrimal glands in the upper eyelids. In these glands, and also with the help of the meibomian glands, a ratio of oil, mucus, and water combine. Once the tear film exits the glands, it is moved across the eyes’ surface by blinking. After moving across the eye, tears move to the inner, lower corner where puncta allow them to drain into tiny tubes. This relatively complex journey could go wrong at multiple points.
What Causes Excessive Tearing?
It may seem reasonable to assume that too many tears in the eye means that the glands at work are overproducing. This isn’t always the case. Often, we find that dry eye syndrome or an inflammatory condition called blepharitis causes excessive tearing. Additionally, tearing may be related to a malposition of the eyelid, such as:
- Entropion, which is an inward turning eyelid. When the eyelid tilts inward, contact between the ocular surface and the eyelashes causes inflammation.
- Ectropion, an outward turning eyelid, can result in irritation and excessive tearing due to a shift in the position of the punctal drains through which tears exit the eye.
