Glaucoma is a disease of the major nerve of vision, called the optic nerve. The optic nerve receives light from the retina and transmits impulses to the brain that we perceive as vision. Glaucoma is characterized by a particular pattern of progressive damage to the optic nerve that generally begins with a subtle loss of side vision (peripheral vision). If glaucoma is not diagnosed and treated, it can progress to loss of central vision and blindness. Glaucoma is usually, but not always, associated with elevated pressure in the eye (intraocular pressure). Generally, it is this elevated eye pressure that leads to damage of the eye (optic) nerve. In some cases, glaucoma may occur in the presence of normal eye pressure. This form of glaucoma is believed to be caused by poor regulation of blood flow to the optic nerve. Symptoms of Glaucoma 1.In initial stages there are no symptoms. 2.In closed-angle glaucoma, blurring of vision and sudden painful attack in one eye occurs. A cloudy cornea, nausea and vomiting, redness of the eye and a halo effect around the object occurs. 3.In open-angle glaucoma, both the eyes are usually affected by loss of peripheral vision, marked by blind spots. Causes of Glaucoma 1.Rise of pressure within the eyeball, increases the quantity of aqueous humor (clear fluid inside the eye that supplies nutrients and carries away waste products away from the lens and cornea) that ultimately damages the optic nerve and causes blindness. 2.People above 65 years of age, anyone with a family history of the disease, people taking B.P. medications or cortisone, severely near sighted and diabetics are at a greater risk, for developing glaucoma. 3.Sudden blockage near the iris cause extreme intralocular pressure that causes permanent blindness within a day or two. This is closed-angle glaucoma. Eye Exercise 'Colour day.' You might be ask to have a 'colour day.' Choose a colour and seem out for it all through the day.
