M. Kok et al., SCHIOTZ TONOMETRY FOR GLAUCOMA - ARE THERE SIMPLE ALTERNATIVES, TM & IH. Tropical medicine & international health, 3(3), 1998, pp. 210-213
In the period from October 1991 until August 1992, 864 eye-patients in
a rural area in south-east Nigeria were examined in order to find sim
ple parameters for the screening of glaucoma simplex. Schiotz tonometr
y was used as the gold standard. Investigation of the pupil-reaction w
ith a torch, estimation of the pressure of the (closed) eye by digital
palpation, and estimations of the cup/disc ratio by ophthalmoscopy ca
n be used as an alternative.
