Glaucoma is characterized by optic nerve damage which results in vision loss, and elevated eye pressure (intraocular pressure) is the primary risk factor. There is growing evidence that other factors may predispose a person to glaucoma damage, including circulation to the eye and optic nerve.
A: Please see your eye doctor immediately. You are describing a serious condition that requires evaluation by your own doctor. There are a variety of causes of eye pain, photophobia, and associated nausea, such as elevated eye pressure. Some of these conditions require urgent treatment to avoid complications. So, again, please see your doctor.
