The main risk factors for falls are musculoskeletal and neuromuscular impairment, impaired visual acuity, hearing loss, use of psychotropic agents, diseases (e.g., Parkinson's disease, dementia, depression, stroke-related impairment, vitamin D deficiency), use of alcohol, sedentary lifestyle, malnutrition, and environmental factors.
Exclusion criteria were severe psychotic diseases, serious drug abuse, chronic degenerative diseases (dementia, multiple sclerosis), severe motor impairments (paresis in both arms), noticeably low intelligence, considerably impaired visual acuity (corrected decimal binocular acuity < 0.4 respectively > 0.4 LogMAR acuity) or inability to fixate.
To the normal effects of aging on the eyes may be added such problems as cataracts (a clouding of the lenses that impairs visual acuity and increases sensitivity to glare), macular degeneration (a gradual loss of central vision) and glaucoma (increased eye pressure that limits peripheral vision).
Corneal clouding, a condition that impairs visual acuity, is associated with numerous diseases, including mucopolysaccharidosis (MPS) type VII.
However, the left eye showed no improvement in CFF (29 Hz) or in subjective symptoms other than impaired visual acuity (1.2).
To assess the efficacy of the anti-TNF monoclonal antibody infliximab in uveitis patients without clinically evident ocular inflammation and impaired visual acuity because of chronic cystoid macular edema (CME).
It is responsible for an estimated number of 20 million cases of blindness and an even greater, but unknown, number of cases of impaired visual acuity [1].
The patients exhibited poor object recognition, sometimes due to impaired visual acuity.
The main features of CVI during ophthalmological investigation are: impaired visual acuity, visual field defects, and abnormal visual behavior, while obvious ocular abnormalities are not found.
At study entry, 39/42 eyes had active uveitis with normal visual acuity in 59% of eyes, impaired visual acuity in 10% of the eyes, and legal blindness in 31% of the eyes.
