Prevalence and Causes of Visual Field Loss in the Elderly and Associations With Impairment in Daily Functioning

Abstract
DECLINE IN visual function with age is well known and is a source of major concern in the elderly population. Besides visual acuity, visual function also largely depends on the intactness of the visual field (VF).1 The prevalence of visual acuity loss in the elderly population has been studied,2 but data on the prevalence of VF loss (VFL) are sparse. Prevalences of VFL ranging from 13% to 17% have been reported in adults 40 years and older3 and in elderly driver's license applicants.4 These studies did not investigate the causes of VFL.
