Vision impairment is associated with increased subjective cognitive decline (SCD)-related functional limitations for adults aged 45 years and older.
“Older adults are at a high risk for vision problems compared to other segments of the population,” said Dr. Joshua R. Ehrlich ,the study’s senior author from the University of Michigan, Ann Arbor.
“Vision impairment, particularly in later life, has many consequences beyond not seeing clearly, including an increased risk of mood disorders.”
Using data from more than 7,500 older men and women, Ehrlich’s team found that far more individuals with impaired vision reported symptoms of depression than those without vision problems: 31 per cent versus 13 per cent.
The same was true for anxiety symptoms, reported by 27 per cent of those with vision impairment and 11 per cent of those without it, according to the results in JAMA Ophthalmology.
At the same time, individuals with symptoms of depression were 37 per cent more likely to develop impaired vision in the future than people without depression, and those with anxiety symptoms were 55 per cent more likely than those without anxiety.
“Vision loss is associated with many adverse health consequences beyond not seeing clearly,” Ehrlich said. “Poor vision not only increases the risk of mood disorders, but also cognitive decline, falls, loss of independence, and even mortality,” he noted.
“However, poor vision is not an inevitable part of ageing, and an estimated 80 per cent of vision loss is preventable or treatable. Accordingly, vision care is a vital component of promoting overall health, well-being, and optimal ageing,” he said.
“In our clinical practice, we observe exactly this, that advanced age associated with low visual acuity generally leads to mood and anxiety disorders,” said Dr Marina Ribeiro from Universidade Federal de Alagoas in Maceio, Brazil, who wasn’t involved in the study.
“This is of clinical relevance, because it works as a warning to family members, who should seek psychological and psychiatric attention for patients with low visual acuity if they observe any change in mood,” she said.
“No one should underestimate the mood swings in patients with low visual acuity,” Ribeiro added.
“What is new and most interesting about this study to my opinion is its bidirectional focus on the longitudinal association between visual impairment and mental health,” said Dr Hilde van der Aa from Amsterdam University Medical Center in The Netherlands, who also wasn’t involved in the study.
“Both mental healthcare professionals and eye care professionals should be aware of the bidirectional association between visual impairment and mental health, to be able to offer tailored support and timely referrals from which patients could directly benefit,” she said.
