Does eye pressure have to be high to have glaucoma?
Not necessarily. In a different form of glaucoma, low-tension glaucoma also called normotensive (normal pressure) glaucoma, intraocular pressure is not high but even just a small increase in intraocular pressure and/or a decrease in blood flow to the optic nerve may play crucial role. Therefore, the goal of treatment is to decrease the intraocular pressure.
