Vision Screening in Hospitals for Older Adults Following a Fall

Aims This study aims to improve the way vision is checked and sight loss treated in older adults (65 years or older), who attend hospital following a fall. Background Falling is common in older adults. As the number of older people grows, the number of falls is expected to increase as well. Falling can affect a person's life in several ways: it can lead to pain, injuries, difficulty doing normal daily activities, weaker muscles, feeling isolated, losing independence and confidence, living in fear of falling, depression, difficulty in recovering from illnesses, developing other health problems more easily and a higher risk of death. Falls are a major health problem for the public and the United Kingdom (UK) spends more than £2 billion per year on caring for older adults who fall. Problems with eyesight are also more common in older age and can have a similar effect on a person's independence, happiness and almost doubles their chances of falling. Sight loss in older age that is linked to falling is often treatable. UK guidelines have been made to help prevent falls. These guidelines recommend checking for and treating sight loss in all older adults who attend hospital following a fall. However, this is only being done in a small number of hospitals. The reasons for this need to be investigated, in order to encourage and make it easier for health professionals to follow these guidelines. Research has also shown that older adults, may be less likely to get their eyes tested regularly and attend hospital eye appointments. There are many reasons for this and vision screening whilst the patient is already receiving care in hospital, may be a good opportunity to address these issues. The views of the public are important for developing screening services that they understand and meets their needs. This study will gather the views of older people and their carers on hospital vision screening after a fall and the importance of looking after their eyes. This study aims to improve the way vision is checked in older adults who attend hospital following a fall. This will help to identify and treat sight loss that may contribute to repeated falling. The study will combine the views of older adults and health professionals, to ensure that changes made meet patients' needs and are sustainable. Design and methods This study will have three parts: 1. Focus groups asking health professionals about checking vision in patients who have fallen. 2. Focus groups asking patients who have fallen and their carers about looking after their eyes. 3. Development of a way of checking vision and treating sight loss in older adults who attend hospital following a fall.

The Influence of Prone Position for Spinal Surgery on Visual Acuity

This study investigated the effect of desflurane and propofol anesthesia on visual acuity in patients in prone position for spinal surgery. Many trials have investigated the effects of different anesthetic agents on intraocular pressure, propofol may reduce intraocular pressure more than other intravenous anesthetics.
