Abstract
Visual impairment (VI) is a devastating disability worldwide
and has been reported to be linked with functional limitations, falls,
depression, cognitive function, and mortality. The health burden
associated with VI has been estimated to be heavier than hypertension,
diabetes, obesity, and hyperlipidemia.
According to the World Health Organization (WHO), the
number of visually impaired people worldwide, in 2010, was
estimated at 285 million .Because more than 90% of visually impaired
people reside in developing countries, WHO approved an action for
“Vision 2020” over the next decade.
It is the source of numerous serious medical, psychological,
social, and economic problems. It is profoundly influences quality of
life. Although prevalence rates vary depending upon the definition
applied, current population estimates indicate that about one fifth of
adults over the age of 60 experience some degree of visual
impairment.
Aging causes slight changes in visual function that reduce
visual acuity (VA). In addition, aging increases the risk of developing
a major eye disease. However, loss of vision to the extent of VI as a
natural consequence of aging is not inevitable, even though some
older adults may assume otherwise.
As visual function is the most important sensory function of the
human body, visual impairment is often detrimental to affected
individuals’ daily life and leads to functional disabilities and other
health problems. Consequently, their quality of life (QOL) may
significantly deteriorate. During the past two decades, an increasing number of studies have investigated the impact of visual impairment
on the QOL of older people. Although some review articles regarding
the association of QOL with ocular disorders emerged in the literature.
This clinical study included 285 patients, was conducted through
random cluster sampling that was conducted to identify participants
among residents ≥60 years of age living in Menoufia governorate.
Presenting visual acuity (PVA) and best-corrected visual acuity
(BCVA) were checked, we excluded those with history of previous
eye surgery.
