Abstract: An ophthalmologic apparatus is provided, which is capable of more securely supporting left and right cheekbone portions of a subject in accordance with the size and shape of the subject's face allowing the subject to respond orally where the positions of the subject's eyes are fixed. The ophthalmologic apparatus includes a forehead contact portion coming into contact with the forehead of the subject, and a cheek contact portion coming into contact with the cheeks of the subject. The cheek contact portion includes a first cheek-contact body that supports one of the cheeks of the subject, a second cheek-contact body that supports the other one of the cheeks of the subject, and an opening/closing mechanism portion that opens and closes in a horizontal direction the first cheek-contact body and the second cheek-contact body in a direction of coming close to each other and a direction of separating from each other

Abstract: An ophthalmic apparatus includes an objective lens, an illumination optical system, an imaging optical system, and an optical path coupling member. The illumination optical system may illuminate a subject's eye with illumination light via the objective lens. The imaging optical system may guide returning light of the illumination light from the subject's eye to an imaging device via the objective lens. The optical path coupling member has a transparent member with a reflective region formed by evaporating a reflective film onto a part of a transmission region of its surface, and is configured to couple an optical path of the illumination optical system with an optical path of the imaging optical system. The transmission region may be arranged substantially conjugate optically to a subject's iris. The illumination light is reflected on the reflective region and the returning light is transmitted through the transmission region.

Abstract: An ophthalmologic apparatus comprises eye information obtaining portions, each of the eye information obtaining portions corresponding to each of subject eyes of a subject and configured to obtain information on each of the subject eyes; imaging portions, each of the imaging portions corresponding to each of the eye information obtaining portions and configured to capture a subject eye image of each of the subject eyes; a reference calculator configured to obtain a three-dimensional reference position in each of the subject eye images captured by each of the imaging portions; an inclination calculator configured to obtain inclination information indicating inclination of relative positions of the subject eyes from the obtained three-dimensional reference positions in the subject eye images; and a notification portion configured to notify the obtained inclination information.
