P. Era et al., SENSITIVITY OF THE CENTRAL VISUAL-FIELD IN 70-YEAR-OLD TO 81-YEAR-OLDMALE-ATHLETES AND IN A POPULATION-SAMPLE, Aging, 6(5), 1994, pp. 335-342
The sensitivity of the central visual field (0 degrees-30 degrees) was
studied using an automatic Octopus 500E perimeter in elderly merle at
hletes and in ct population sample of men of corresponding age. The at
hletes (N=96) were endurance and power athletes, who were still active
in competitive sports with training histories spanning tens of years.
The athletes' results were compared with those of ct sample of men of
the same age (70-81 years, N=41) randomly selected from the local pop
ulation register. The sensitivity values of the athletes, and the endu
rance athletes in particular were significantly better than those of t
he controls, with differences varying from 1 to 2.5 dB in the differen
t areas of the central visual field. Multivariate analyses of the back
ground factors of visual field sensitivity showed that the most import
ant were age, amount of annual training, number of chronic diseases, H
DL-cholesterol level, and vital capacity. The results suggest that a l
ong training history, especially of the aerobic type, may be beneficia
l with respect to the sensitivity of the visual system.
