ABSTRACT:
An ophthalmic measurement apparatus for measuring biological properties by scanning the anterior chamber of an eye two-dimensionally with a laser beam. Light received from the anterior chamber is measured at a plurality of measurement points in a target measurement range defined by the two-dimensional scanning. A representative background value at each of the measurement points is calculated from the received light and compared with a reference value to provide an alignment rank level indicative of the state of alignment. The state of alignment is determined according to the alignment rank level. A difference value between the representative background values or a standard deviation at the measuring points is calculated and compared with an associated reference value for improving the determination of the state of alignment.
