Abstract: The present invention reduces a positional displacement of an acquired image attributable to a delay from the issuance of a drive instruction to a scanner to the scanner actually reaching an instructed drive position. An ophthalmologic apparatus has a light scanning unit which scans measuring light on an eye to be examined, an acquisition unit which receives light reflected from the eye to be examined and acquires a light receiving signal, and an instruction unit which instructs the drive position of the light scanning unit. The apparatus further includes a position detection unit which detects the current position of the light scanning unit and a measurement unit which measures the drive time delay from the issuance of an instruction by the instruction until the current position reaches the instructed drive position. The acquisition unit starts acquiring the light receiving signal at timing based on the drive time delay.

Abstract: A non-contact ophthalmologic apparatus includes: a storage unit for storing measurement results of an intraocular pressure of an eye to be inspected as statistical data; a condition determination unit for determining a measurement range of an intraocular pressure value based on the statistical data; and a control condition determination unit for determining, based on the measurement range determined by the condition determination unit, a control condition of a fluid ejection unit for ejecting air toward the eye to be inspected. Thus, it is possible to eliminate a need to eject high-pressure air even in the first measurement of the intraocular pressure of the eye to be inspected, thereby alleviating a burden on a subject.
