In a study of older adults, it has been found that visual impairment was linked to worsening cognitive function. The two problems of visual dysfunction and poor cognition are highly prevalent in older adults.
– The number of people who suffer from vision problems is expected to double by the year 2050.
– The researchers studied people 65 years and older and found that visual impairment was associated with worse cognitive function.
– Further research will be required to provide a better understanding of relationships between both visual decline and cognitive decline.
From a policy perspective, should causality be established, this may contribute to the value of vision screening, not only to identify patients who may benefit from treatment of correctable eye diseases but also to suspect broader limitations in function from cognitive and directly visual tasks.
