Glaucoma Treatment England

Glaucoma is a disease in which the optic nerve is damaged, leading to progressive, irreversible loss of vision. It is often, but not always, associated with increased pressure of the fluid in the eye. The nerve damage involves loss of retinal ganglion cells in a characteristic pattern. One person may develop nerve damage at a relatively low pressure, while another person may have high eye pressure for years and yet never develop damage. Untreated glaucoma leads to permanent damage of the optic nerve and resultant visual field loss, which can progress to blindness.

A cataract is a condition of the eye that makes it difficult to see. The lens, the part of the eye that we use to focus, becomes clouded. The eye is like a camera with a lens system at the front and a photosensitive area at the back. The normal function of the lens is to focus light so that you can see sharp clear images. If the lens of the eye becomes cloudy, it restricts the amount of light that is able to enter the eye, reducing the eyesight. A cataract usually develops gradually, eventually making it difficult to carry out your daily activities. If the cataract is not removed, your vision usually becomes worse over time. One or both eyes can be affected, but a cataract cannot spread from one eye to the other.
