Glaucoma in the United States Over the Last Ten Years :: Pathology Health Medical Eye Diseases Essays

Glaucoma in the United States Over the refinement Ten YearsThis research paper examines glaucoma over the age of 40 in the United States, in the last 10 years. Knowing the event that glaucoma is the second leading cause of blindness in the United States leads us to choose this subject for research. Glaucoma is a group of eye diseases that gradually steals imagination without warning and often without symptoms. Vision loss is caused by damage to the opthalmic nerve. This nerve acts like an electric cable with over a trillion wires and is responsible for carrying the images we see to the brain. The two of import types of glaucoma are open locomote glaucoma, or primeval open angle glaucoma (POAG), and angle closure glaucoma. Currently, in that respect is no mend for glaucoma. Glaucoma is a chronic disease that must be treated for life. However, much is happening in research that makes us promising a cure may be realized in our lifetime. in that respect is exciting work being conducted by scientists all over the human in the areas of genetics, neuroprotection and neuroregeneration. These areas of study deal with the origins and pathology of glaucoma as opposed to managing symptoms. A cure is on the way.Glaucoma over the Age of Forty in the United StatesThe border glaucoma encompasses a group of eye diseases, not a single entity. Glaucoma is describe broadly speaking in terms of aqueous fluid drainage by the trabecular meshwork, the major outflow pathway. There are two main types angle closure glaucoma and open angle glaucoma. Open angle glaucoma is removed more than common in the United States. The American Academy of Ophthalmology defines primordial angle closure glaucoma as An appositional or synechial closure of the introductory chamber angle caused by relative pupillary block in the absence of other causes of angle closure. The American Academy of Ophthalmology defines primary open angle glaucoma as a Multifactorial optic neuropathy in which there is a characteristic acquired loss of optic nerve fibers. Classifying glaucoma broadly into angle closure glaucoma or open angle glaucoma is helpful from two a diagnostic and pathophysiological perspective. Problem StatementIn the United States, around 2.2 million people age 40 and older have glaucoma, and of these, as many as 120,000 are blind due to the disease. The number of Americans with glaucoma is estimated to emergence to 3.3 million by the year 2020. Each year, there are more than 300,000 new cases of glaucoma and approximately 5,400 people suffer complete blindness.
