[A monkey chair specially designed for ophthalmic examinations and intraocular pressure measurement in the conscious cynomolgus monkey].
We constructed a monkey chair specially designed for ophthalmic examinations such as biomicroscopic examination, applanation tonometry etc. It was made of stainless steel and acrylic plastic, equipped with a protection plate for the experimenter, and adjustable to the size of the monkey. Using this chair, intraocular pressure (IOP) measurements of a fully conscious cynomolgus monkey were carried out at intervals of one or two hours from 10:00 AM to 10:00 PM. The IOP, at 6:00, 8:00 or 10:00 PM was compared with the IOP measured at the same time of the day after one or two weeks. The IOP while fully conscious showed diurnal variation (p < 0.001, ANOVA). The IOP measured at the same time of the day at one or two week intervals showed reasonable reproducibility.
