What Are Drainage Disorders?
In order for the eye to function properly, it must be kept well lubricated. Accordingly, there is an extensive system of glands that produce different components of the tears that work together to form a functional tear film. This tear film is crucial to protecting the delicate surface of the eye, keeping the eye comfortable, and maintaining crisp vision. However, if there are too many tears covering the eye, this phenomenon can cause significant problems. Patients with excess tearing will often notice: blurred vision, constant tears streaming down the face, redness and skin irritation from constantly dabbing tears, and recurrent infections.
The exact cause for the excessive tearing can sometimes be difficult to uncover. This problem can occur if there is an overproduction of tears, decreased drainage of tears, or a combination of the two.
Overproduction of tears may be related to several ocular conditions that will signal your tear gland (lacrimal gland) to produce extra tears. Causes include:
- Dry eyes
- Ocular surface irritation
- Eyelid inflammation (blepharitis)
The aforementioned conditions can be treated with artificial tears, allergy drops, anti-inflammatory drops, antibiotic drops or ointments, and oral medications.
