What is high eye pressure and how does it damage the vision?
The eye is filled with a fluid (aqueous), which is there at a certain pressure, called intraocular pressure (IOP). This fluid is continuously formed within the eye and is also simultaneously drained out, to maintain a stable pressure. The blockage of the normal outflow mechanism generally leads to an increase in the pressure, which damage the optic nerve of the eye. The optic nerve connects the eye to the brain and relays the visual signal. This damage to the optic nerve results in loss of peripheral visual fields initially and later on affects the central vision as well. What are the types of glaucoma? There are two main types of glaucoma- 1) Open angle glaucoma is the commoner form and it leads to slowly progressive loss of vision. 2) Closed angle glaucoma is also called acute glaucoma. The sudden blockage of fluid outflow from the eye leads to severe pain, nausea, vomiting and blurred vision. This is a medical emergency requiring immediate treatment or else blindness may occur in a
