Ophthalmic mission - Essay ExampleThis is to distinguish the normal elevation of intraocular pressure seen in otherwise normal individuals. measuring of intraocular pressure is thus one of the first completely new skills that a new ophthalmic entertain practitioner must master. Therefore, knowledge about it is important. Measurement of the intraocular pressure in a large egress of normal subjects reveals a normal distribution extending from pressures of 10-12 mmHg to 25-28mmHg (Rossetti et al., 2008, 1053). The pattern of distribution fits a Gaussian curve, so that the volume of subjects have a pressure of about 16mmHg. For clinical purposes, it is necessary to set an arbitrary upper find of normal. By and large, the eye can stand low pressures remarkably well, but when the pressure is abnormally high, the circulation of line of products through the eye becomes jeopardised and serious damage can ensue. For clinical purposes, an upper level of 21 mmHg is a great deal accepted. Above this level, suspicions are raised and further investigations undertaken. Thus amount of IOP is a significant initial clinical diagnostic step that determines further course of action in such patients (Collaer, Zeyen, and Caprioli, 2005, 196-200). Many nurses need to recital the skill of this measurement since accuracy is a very important parameter leading to the further travel in the ophthalmic care pathway.RationaleNow, the question is, why I have chosen measurement of intraocular pressure to demonstrate my skill as a new specialist nurse. Glaucoma is second only to cataract as a leading suit of clothes of worldwide blindness and is the leading cause of irreversible visual loss, generally due to primary open-angle glaucoma (POAG). In 2002, it was estimated that 161 one thousand million individuals worldwide had visual impairment and 37 million were blind. Glaucoma accounted for 12.3% of global blindness, Bilateral blindness from glaucoma is projected to affect 8.4 mil lion individuals worldwide by 2010 and greater than 11 million by 2020. Globally, glaucoma is a significant cause of vision loss that disproportionately affects women and Asians (Cedrone et al., 2008, 3-14). While increased IOP is a strong fortune factor for the development of glaucoma, it must be remembered that many people with glaucoma have untreated IOPs of 21 mm Hg or less. Elevated intraocular pressure (IOP) is the most important known risk factor for the development of POAG, and its reduction remains the only clearly proven treatment. Several studies have substantiate that reduction of IOP at any point along the spectrum of disease severity reduces progression (Bowling, Chen, and Salmon, 2005, 1102-1104). The Collaborative popular Tension Glaucoma Study has revealed that IOP reduction reduces the development of POAG in patients with ocular hypertension and reduces progression in patients with glaucoma scorn normal IOP (Anderson, and Normal Tension Glaucoma Study, 2003, 86 -90). In the UK, as mentioned by Kroese et al. (2002), glaucoma is, indeed, the second most common cause of blindness as estimated from blindness certification. This accounts for 11.7% of all certifications. In the age group of
