oa South African Family Practice - Common eye disorders in the elderly - a short review : CPD
As the eye ages, certain changes occur that may affect vision. <i>Presbyopia</i> is corrected by the use of reading glasses.<i>Cataracts</i> are common and vision can be restored following a reasonably simple operation. Visual loss due to <i>glaucoma</i> can be minimised by early detection and treatment, but once vision has been lost it cannot be recovered. Much research is being done on the treatment of <i>age-related macular degeneration, </i> but this currently remains the main cause of irreversible loss of vision in the elderly. Results of <i>macular hole</i> surgery are improving due to improved surgical techniques and better diagnostic equipment (Optical Coherence Tomography). Underlying vascular disease (systemic hypertension, diabetes, atherosclerosis, vasculitis) is usually present in patients with <i>retinal artery occlusion, retinal vein occlusion</i> or <i>anterior ischaemic optic neuropathy.</i>
