摘要： In an ophthalmologic apparatus comprises an illumination optical system for directing illumination light onto a prescribed point of an eye under examination, and an observation optical system for observing an image of the prescribed point of the eye under examination formed through an object lens. The object lens is movably supported along its optical axis between a first position at which the image point falls at its object point and a second position at which the prescribed point of the eye under examination falls at its image point. As a result, there is a change in the conjugate relationship so that a sharply focused image can be observed when the object lens is at either position thereby making it possible to observe sharply focused images of different magnifications simply by moving the object lens.

摘要： There is provided a perimeter that allows a reliability evaluation to be performed in a kinetic visual field examination. A stimulus for examination is displayed onto an inner surface of a visual field dome and moved at a constant speed on a meridian toward the center of the dome. A subject responds to the stimulus for examination when he visually recognized the moving stimulus. There is displayed a false-negative stimulus, which is more visible than the stimulus for examination, or a false-positive stimulus, which corresponds to the operating sound of the perimeter without any stimulus display. The visual field examination results are evaluated on the basis of a response made by the subject to the false-negative and the false-positive stimuli.This arrangement allows the reliability of the examination results in a kinetic visual field examination to be satisfactorily evaluated.

摘要： When a Landolt ring optotype is presented in a visual acuity testing unit, an examinee answers a position of a slit of the optotype through an operation of a joystick lever or the like. If an examinee gives a right answer within a standard time at a first presentation of optotype, examination at a higher visual acuity grade is executed by presenting a smaller Landolt ring optotype. In case of a right answer over the standard time, reexamination at the same visual acuity grade is executed twice at the most. If a right answer is given at least once, examination at a higher visual acuity grade is executed. In case of a wrong answer within the standard time at a first presentation of optotype, reexamination at the same visual acuity is executed only once. If the right answer is given at this reexamination, examination at a higher visual acuity grade is executed. Reexamination is thus executed, so that the result of the examination is correct. In addition, the examination time can be shortened since necessary number of times of reexaminations is minimum.
摘要翻译：当在视力测试单元中呈现Landolt环视标时，受试者通过操纵杆等的操作来回答视标的狭缝的位置。如果考生在标准时间内在首次出现视标时给出正确答案，则通过呈现较小的Landolt环视标来执行较高视力等级的检查。如果在标准时间内有正确的答案，则以相同的视力等级再次进行两次检查。如果至少给出一次正确的答案，则执行更高视力等级的检查。如果在第一次呈现视标的标准时间内出现错误的答案，则以相同视力进行复检只能执行一次。如果在该复查中给出正确的答案，则执行较高视力等级的检查。因此执行复审，使检查结果正确。此外，考虑时间可以缩短，因为必要的再次次数最少。

摘要： A vision tester comprises a slide projector for projecting a visual indication chart onto a curved display screen via a mirror rotated by a motor. The center of curvature of the curved display screen substantially coincides with the subject's eye. The rotation of the mirror causes an image of the visual indicator to be moved across the screen in a specific direction. When the subject provides a response to the moving image, the speed of image movement at the time of the response is detected and stored in a memory. The average of a plurality of such measurements is used to determine the subject's dynamic visual acuity.

摘要： A perimeter performs a kinetic visual field examination on the basis of a response as to whether a subject visually recognizes a displayed stimulus for kinetic visual field examination. The stimulus is displayed a series of times on an inner surface of a visual field dome. An operation is performed in which the subject is made aware of an operating sound of the perimeter while no stimulus is actually displayed. The operation is performed at a predetermined frequency during the display times of the stimulus, and a duration of the operation is determined in accordance with a response time by the subject to the displayed stimulus. The reliability of the kinetic visual field examination is evaluated on the basis of the response of the subject in the performed operation.

摘要： A perimeter has an optical projection system that projects a target spot on the inside surface of a visual field dome. The position at which the target spot is projected is controlled electronically. Input devices are used to input control information to control the target spot projection position and to record patient response information. A display means provides feedback display of the control information and patient response information, and also functions as an input screen via which the control and response information is input.
