Retinal light sensitivity of the central visual field among 70- to 81-year-old men and women.
2009
Retinal light sensitivity of the central visual field (0-30 degrees), visual acuity, intraocular pressure and pupillary size were screened in 42 men and 42 women aged 70 to 81 years. The subjects were randomly selected from the population register. After excluding the diagnosed glaucoma cases, the men had better visual field light sensitivity values than the women. They also had lower intraocular pressure and a wider pupillary diameter than the women, whereas there were no differences in visual acuity between the sexes. When the effect of pupillary size was controlled the differences in visual field light sensitivity values between men and women became non-significant. Among these elderly p…
Sensitivity of the central visual field in 70- to 81-year-old male athletes and in a population sample.
1994
The sensitivity of the central visual field (0°–30°) was studied using an automatic Octopus 500E perimeter in elderly male athletes and in a population sample of men of corresponding age. The athletes (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 a sample of men of the same age (70–81 years, N=41) randomly selected from the local population register. The sensitivity values of the athletes, and the endurance athletes in particular, were significantly better than those of the controls, with differences varying from 1 to 2.5 dB in the different areas of the …
