Hg, females having significantly higher pres-
sures than males.
Of all examined 62.8% had equal intra-
ocular pressure in both eyes. In only 5% the
difference was more than 3 mm, the left eye
having more often higher pressure than the
right eye.
Glaucoma was found in 2.67% of the material
with a significant increase in frequency in
persons over 60 years and at intra-oeular pres-
sure of 24 mm Hg, with a higher rate for males
than females.
The intra-ocular pressure of non-glauco-
matous subjects did not vary significantly
over an observation period up to 11 years.
