Theory to Practice Analysis : Eye Conditions in Older Adults

.......................... 6 References ........................................................................................................................... 7 Introduction Older adults, as compared to the general population are liable to suffer more than one health issue at a time; in fact, some of these health problems can simultaneously manifest on older adults. One common health problem is eye disorder. Eye disorders are common among older adults because of expected wear and tear and ageing processes setting in on these patients. This paper will discuss eye disorders among older adults. It shall first explain the normal age-related vision changes during old age; then it would discuss these eye disorders, including cataracts, age-related macular degeneration, and glaucoma. It would also discuss the activities of daily living affected by eye conditions. Finally, it shall identify the various issues related to these activities, including the carer and patient advice which can be given in order to improve the patient’s condition. This study is being carried out in order to establish clear guidelines relating to the care of ageing patients, especially in relation to specific health afflictions. Analysis of eye conditions Normal changes There are several expected changes in a person’s eyes as a person grows older. Firstly, the older adult is likely to experience the dry eye syndrome, mostly attributed to less tears or moisture produced by conjunctiva . The ageing of the cornea also causes reduced light into the eye, causing light to be deflected in all other places in the eyes. With ageing, the collagen fibres thicken and this compromises the ability of the iris to dilate and to constrict, making it difficult to make the easy transitions to light and dark . The lens of the eyes also become less concave, and become more flat, thereby causing compromised vision. In relation to visual functions, the eyes are also less able to focus on nearby objects or to farther objects . There is also less contrast sensitivity due to adjustments in the neural pathways. There is narrowing of the peripheral vision, making it more difficult for the older adult to maintain peripheral vision in his eyes. The patient is also less able to tell colours apart, as well as to identify objects from a far distance. Cataracts The above changes often cause various illnesses, including cataracts, age-related macular degeneration, and glaucoma. Cataract, according to the World Health Organization (2011, p. 2) is the “clouding of the lens of the eye, which impedes the passage of light”. This disease is also a common risk factor among diabetes patients, and is exacerbated by prolonged exposure to sunlight, smoking and alcohol. It is considered as one of the world’s leading cause of blindness and in Australia, it is the second most common cause of unilateral blindness and moderate visual issues . As one gets older, cataract also increases, and as the general population starts to age, the incidence of cataract is also liable to increase. In order to manage this condition, the intraocular lens implant surgery is the most common corrective procedure . With the proper application of interventions, it is possible to ensure the early treatment of the patient’s condition management of the disease. Age-related macular degeneration Age-related macular degeneration is a common cause of visual loss in the world. It refers to a “disorder of the macular area of the retina characterized by soft or confluent drusen, areas of increased ...Show more
