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

Abstract

To determine the prevalence and causes of visual field loss (VFL) and the association between VFL and indicators of impairment in daily functioning.

Central and Peripheral Visual Impairment and the Risk of Falls and Falls with Injury

“…However, prior results from this same cohort 13 using a predictive model, showed no association with any of the two vision measures when falls were evaluated retrospectively, as in our study. Our results are consistent with other longitudinal studies that have found that both measures of visual impairment are associated with falls 38 or have found that either visual acuity 8, 39 or visual field loss 9, 14, 16 are associated to falls and falls with injury.…”

Integrating Geospatial Data and Measures of Disability and Wealth to Assess Inequalities in an Eye Health Survey: An Example from the Indian Sunderbans

“…However, the data highlighted a number of other inequalities that still remain in the area. Similar to other studies [22,23], we found that the prevalence of blindness was higher among women (1.1% compared to 0.5%). Blindness and other types of visual impairment were also much higher among people with non-visual disabilities.…”

Associação entre déficit visual e aspectos clínico-funcionais em idosos da comunidade

“…There was correlation between the number of falls of older adults and the values of the Snellen chart in this study, confirmed by the fact that older adults with low vision were more advanced in age and less mobile compared to older adults with normal vision. The relationship between falls and visual impairment was demonstrated by some authors 1,2,29 , as was the relationship between falls and age 12,14,30 , falls and mobility and falls and difficulty performing ADLs 10,29 , corroborating the findings of the present study. Individuals with bilateral visual field loss, even with visual acuity ≥ 0.3, are six times more like to fall than older adults without visual field loss 1 , which indicates that not only visual acuity but also visual field loss are related to the risk of falling thousand blind people and the rest with significant visual impairment 31 .…”

“…The equivalence between methods can be calculated by the standard equation [0.1 x test distance in meters/5], which provides the final value in decimal scores 10 . In the present study, values below 0.3 (or its equivalent fraction 20/60 and 6/18) are indicative of low vision, as adopted by several authors 1,6,20 . For the assessment of functional capacity, the Brazilian OARS Multidimensional Functional Assessment Questionnaire (BOMFAQ) 21 was applied.…”
