Dry Eye
  If I have dry eyes, why do my eyes 'water' all the time?   Good natural tears are more like an oil which helps lubricate the eyes. When our eyes are tearing a lot the tears are more water like which provides only short term relief.
  What causes dry eye   Aging, medication, and a variety of systemic disease can cause or exacerbate dry eye.
  What treatments are available once the diagnosis of dry eye is made?   Artificial tears help lubricate the eye more like an oil. Punctal plugs can also be inserted into the tear ducts to help maintain your tears to allow greater exposure time.

The weak blood vessels will sometimes cause bleeding or swelling in the retina or tissues in the back of the eye. Early in the disease, the small changes may not affect the vision. Undetected, the damage can progress and eventually cause you to lose vision.
  If you do not hav any diabetic changes found during the exam, when do you need to be seen again?   Doctors generally recommend yearly exams for stable patients.
