Abstract
The apparatus of the invention comprises means for examining the human eye for the onset of glaucoma. The eye undergoing examination forms one plate of a virtual capacitor the other plate of which is formed by a gas nozzle. The body of the person undergoing examination and the gas nozzle are connected to the input of a signal converter the output of which is sampled at a predetermined instant by a sampling and sample-holding means. A gas jet from the nozzle is directed at the eye and a sample made of the output of the signal converter. An indicator connected to the sampling and sample-holding means provides a measurement of the deformation at the surface of the eye caused by the dynamic pressure of the gas jet. Sampling may be carried out at moments determined by the systolic rhythm of the person being examined. Preferably samples are taken at the systolic and diastolic moments thereof, the samples being compared to give an indication of the dynamic performance of the eye.
