PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus capable of performing a Z alignment for the corneal endothelium even when reflection light of the corneal endothelium cannot be detected.SOLUTION: The ophthalmologic apparatus includes a divergent light projection optical system 400 for diagonally radiating light to a cornea C of an eye E to be examined and an observation illumination optical system 120, and a divergent light reception optical system 410 for receiving reflection light that is radiated by these radiation optical systems and reflected by the cornea C, and a focus position detection optical system 60. The ophthalmologic apparatus detects reflection light that is reflected by the corneal endothelium out of light-reception signals that the focus position detection optical system 60 receives, performs a precision Z alignment for the position in the corneal endothelium on the basis of the detected reflection light, and, when the reflection light reflected by the corneal endothelium is not acquired, performs the precision Z alignment on the basis of epithelial reflection light reflected by the corneal epithelium.COPYRIGHT: (C)2015,JPO&INPIT【課題】角膜内皮の反射光を検出することができなくとも角膜内皮に対してZアライメントを行うことのできる眼科装置を提供する。【解決手段】被検眼Eの角膜Cに向けて斜めから光を照射する発散光投影光学系400及び観察用照明光学系120と、これら照射光学系で照射されて角膜Cで反射した反射光を受光する発散光受光光学系410及び合焦位置検出光学系60とを備え、合焦位置検出光学系60が受光する受光信号のうち、角膜内皮で反射する反射光を検出するとともにこの検出した反射光に基づいて、前記角膜内皮の位置に対する精密Zアライメントを行い、角膜内皮で反射する反射光が得られないとき、前記角膜上皮で反射する上皮反射光に基づいて、精密Zアライメントを行う。【選択図】 図2
