Abstract

Background: Presbyastasis is a term used to describe the balance deficiences that appear in older individuals. One of the main features of presbyastasis is the bilateral vestibular hipofunction. The bilateral vestibular hipofunction affects the vestibulo-ocular reflex (VOR) leading to oscillopsia.

Material and method: A comparative study between two groups ofpatients: a group of 16 patients diagnosed with presbyastasis and a second control group includind 11 healthy subjects. The aim of the study was to asses the disturbances of the visual acuity in pacients with presbyastasis. The static visual acuity and the dynamic visual acuity were measured using a Snellen chart.

Results: The dynamic visual acuity was severely impaired in patients with presbyastasis in wich the difference between the static and the dynamic visual acuity represented more then four lines.

Conclusion: The dynamic vizual acuity can be used in the diagnostic protocol of the balance impairments that appear in bilateral vestibulopaties, such as presbyastasis.
