Exercise does not increase visual field sensitivity.
The effect of exercise on visual field sensitivity was investigated for both static and kinetic visual fields using the Humphrey Field Analyser (HFA). The visual fields of 20 young visually normal subjects were measured before and after a 10-min controlled period of exercise. Ten of these 20 subjects then formed a control group, where the same experimental regime was followed without the exercise period. A significant increase in mean static sensitivity in the superior field was found as a result of exercise; however, this is likely to be a learning effect as a similar increase was also found for the control condition. Exercise had no other effect on either the kinetic or static visual fields.
