Glaucoma is a disease of the eye that frequently occurs in older people. The eyeball becomes tense and hard. An increased pressure occurs inside the eyeball. Glaucoma causes disturbances in the flow of blood in the veins of the eye. The tension within the eyeball may destroy the delicate structures, and press the optic nerve backward.
One kind of Glaucoma may cause great pain in the eye, headache, and gradual loss of vision, while another variety is painless. The cause of Glaucoma is not yet known. It’s often accompanied with hardening of the arteries and high blood pressure and may be hereditary. Glaucoma should be treated as soon as possible by a competent medical eye specialist. Doctors use such drugs as pilocarpine and eserine to treat Glaucoma. They prove effective in the early stages of the disease. Advanced cases require surgical operations.
