Age-related deterioration of rod vision in mice [PDF]

open access: yes, 2010
Even in healthy individuals, aging leads to deterioration in visual acuity, contrast sensitivity, visual field, and dark adaptation. Little is known about the neural mechanisms that drive the age-related changes of the retina and, more specifically ...

Differential visual acuity – A new approach to measuring visual acuity

open access: yesJournal of Optometry, 2020
A novel type of acuity measurement, which we refer to as 'differential acuity', requires the observer to identify one unique target among three others which are identical. This is a proof of concept study aimed to determine if differential acuity is equivalent to standard measures of recognition acuity.To create a range of visual acuity, vision was ...

Are we testing visual acuity adequately?

open access: yesCommunity Eye Health Journal, 2018
Visual field testing has benefited from advances in computerised technology and is considered highly accurate and reliable, whereas visual acuity testing still relies on the examiner to apply their best judgement. Is it time to reconsider?
