Abstract:
1. An ophthalmic apparatus comprising: a first optical system for observing a subject's illuminated eye; a second optical system for changing an observation area through the first optical system, the second optical system being moved into a light path of the first optical system when an anterior-ocular image of the subject's eye is to be observed, the second optical system being removed from the light path of the first optical system when a fundus of the subject's eye is to be observed; a first fixation-target projecting unit for anterior-ocular observation disposed within the second optical system and configured to project fixation targets for anterior-ocular observation onto the subject's eye at positions not coinciding with a center of the light path; a second fixation-target projecting unit for fundus observation configured to project fixation targets for fundus observation onto the subject's eye; and a controller that allows the second fixation-target projecting unit to project the fixation targets for fundus observation onto predetermined positions on the subject's eye when the second optical system is removed, said predetermined positions corresponding to the positions to which the fixation targets for anterior-ocular observation are projected.
