Dry eye is a common and progressive condition that affects different populations of patients and varies in severity and underlying causes.
Symptoms of dry eye include:
- Foreign Body Sensation (sand in eyes)
- Blurry vision
It may sound counterintuitive that dry eye causes excessive tearing. It happens because the cornea gets irratated due to the lack of tears in order to compensate for the irratation t reflux tears are released from the lacrimal gland. Tears from the lacrimal gland do not contain a the top lipid layers that keeps tears from evaporating, and are thus not an effective way of lubricating the eye.
Dry eye may get worse during winter time, due to dry air and forced air heating and during spring time due to allergies.
Dry eye may be influenced by hormonal imbalances (menaposes) and medications such as birth control pills. Certain health conditions such as diabetes, thyroid disease, lupus and reumatoid arthritis Sjorgen’s syndrome contribute to dryness.
Post LASIK and cataract surgery patients may complain of higher insicences of dry eye post surgery.
We will discuss different options of treating dry eye symptoms in the next blog post, so stay tuned.
