Abstract

An ophthalmological measurement apparatus wherein the interior of a patient's eye is irradiated with a laser beam and the scattering of the laser beam is measured to determine protein concentration in the oculi anterior. The apparatus is provided with scanning means for scanning the measurement zone during alignment of the eye as well as during measurement. During alignment the measurement zone is scanned at high speed by the laser beam and at the same scanning width as the scanning width used during measurement, and the signal obtained from the photosensor at this time is processed to provide information on and an indication of the appropriateness of the state of alignment. This makes it possible to observe any harmful light rays that will actually appear during measurement.
