Glaucoma is the name for a group of eye conditions where the pressure within your eye is raised to such a degree that the optic nerve becomes damaged and you begin to lose your vision. If it's treated early, the complications of glaucoma can be prevented. Glaucoma is a condition in which the eye's intraocular pressure (IOP) is too high. This means that your eye has too much aqueous humor in it, either because it produced too much, or because it's not draining properly. Other symptoms are optic nerve damage and vision loss. In glaucoma, eye pressure plays a role in damaging the delicate nerve fibers of the optic nerve. cialis discount generic volume order viagra online consumer discount rx cheapest viagra on line online pharmacy pfizer viagra
