Glaucoma is a common eye condition in which your optic nerve, the bundle of nerves at the back of the eye, which feeds visual information to the brain, is damaged because of high inner eye pressure, known as intraocular pressure. This condition can lead to total permanent blindness in a short amount of time if it is not treated properly. Furthermore, glaucoma usually has no noticeable symptoms, and patients diagnosed with glaucoma usually note that they did not feel or notice anything unusual about their vision at all. So, what can be done to detect glaucoma, and how can you prevent it?
