From some expertise's study, we can find, the glaucoma is a complex elusive eyes disease, increased pressure in the eyeball is the main feature of glaucoma. And the injury of optic nerve, visual field defect are the other reason which may cause it. Long time's high pressure in the eyeball will lead to partial injury or integral visual nerves to reduce the information that the nerves sending to the brain, the patient's vision will gradually decrease till blindness. As for the dry eye, it may be caused by eyes infection or eyes fatigue. However, the other reason of dry eyes may be caused by the common term of xerosis of conjunctiva. It's the eyes symptom of tear film's pathological change, thus the cornea and conjunctiva without normal moist and feel dry. It will lead to blurred vision in a long time. However, I find there are nothing relative with the glaucoma and the dry eyes.
