title: Visual loss and falls: a review.
abstract: Falls are an important health issue. They cause significant morbidity and mortality particularly in older people, and also have marked psychological effects on the individual. The literature focuses particularly on older adults, an age group in which both visual impairment and falls are more prevalent, as is the associated morbidity. In this review, we summarise the current literature and point to further studies which need to be undertaken. The consequences of falls are well recognised, and there has been considerable work into identifying risk factors. Changes in visual components such as visual field, acuity, contrast sensitivity and stereopsis all have a part and the co-existence of other sensory impairments certainly increases the risk of falls. However there remain considerable gaps in our knowledge of the relationship between visual loss and falls, for example in patients with diabetic eye disease. Furthermore, there is also conflicting data as to the importance of different visual components. Various interventions, such as programmed inter-disciplinary involvement, have shown promise, however these need further confirmation of their efficacy and cost effectiveness. An added confounder may be that an intervention (eg, cataract extraction) paradoxically affects an individual's future activity level and behaviour, thereby increasing the risk of falling. With an ageing population the importance of this topic is likely to increase, as will the potential benefits of optimising our assessment and management of these patients.
