What is glaucoma?
Today, in search of a precise definition of what glaucoma is, you can find information about a serious eye disease. This chronic eye disease is characterized by such symptoms as a constant or periodic increase in intraocular pressure, accompanied by the development of trophic disorders affecting the retina and optic nerve. Against this background, defects appear in the field of view, and a regional excavation of the nerve disk is developed.
The concept of "glaucoma" unites a large group of eye diseases, accompanied by a number of common features, such as intraocular pressure, the development of characteristic lesions of nerve fibers and the occurrence of visual function disorders. Today there is no single view on the causes of the occurrence and the mechanism of development of glaucoma. This disease can develop at any age, which occurs more often in the elderly. Glaucoma with delayed treatment causes irreversible blindness.The World Health Organization notes glaucoma as the main disease leading to loss of vision. In this case, the disease may sudden onset of blindness in acute glaucoma attack.
Symptoms of glaucoma
But in order to diagnose such a terrible disease in time, it is necessary to know exactly how glaucoma appears. Symptoms may occur as a blurred vision, heaviness and pain in the eyes. Also among the symptoms are marked rez and narrowing the field of view. As a result, there is a significant deterioration in vision and in bright light, "rainbow circles" are seen.
Glaucoma occurs in one of two possible forms - acute-angled, which is the most frequent, or closed-angle. In acute glaucoma, there are practically no symptoms, making it difficult to recognize the disease in a timely manner. Due to the gradual (often over several years) narrowing of the field of view, invisibility with one eye can be detected by chance. Sometimes, in this form of glaucoma, rainbow circles periodically appear when looking at the bright light and complaints associated with misting.
Angular angle glaucoma is characterized by accumulation of intraocular fluid, which causes the angle of the anterior chamber to overlap with the iris. The result of these processes is an increase in pressure, which can trigger the onset of an acute attack of glaucoma, accompanied by a number of symptoms, including sharp eye pain, obvious visual disturbances, redness of the eye, and so on.
