本発明は固定された被検者の規準に合わせてドームを移
動し固視を行う方式の視野計に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a perimetry system in which fixation is performed by moving a dome in accordance with the standard of a fixed subject.
従来被検者の同視を行うためには、被検眼をドームの中
心に固定するだめまず顔合及び前額当てを使用して被検

て視野を測定していた。Conventionally, in order to perform simultaneous viewing of a subject, the subject's eyes must be fixed at the center of the dome. First, the subject's head is fixed using a facial support and a forehead support, and the examiner moves from the center of the dome. I looked through the telescope to make sure it was fixed, and then moved the target to measure the field of view.

検者の規準を確認する必要がある等煩わしく、さらに、
正確な視野の計測に支障を来たす等の欠点があった。However, with this method, the examinee moves his or her eyes to standardize the designated position of the dome, which is the center of the dome. It is fine if the subject is facing the specified fixation position, but if the fixation is shifted even slightly, the subject is forced to maintain tension to always maintain the specified fixation position, and the examiner is also forced to It is cumbersome, such as the need to constantly check the subject's standards in order to maintain fixation under certain conditions;
There were drawbacks such as interfering with accurate measurement of visual field.
本発明はかかる実状に鑑みてなされたものでおって、固

的とするものである。The present invention was made in view of the above circumstances, and the dome is moved in accordance with the fixed position of the subject's eyes, so that the designated position of the subject matches the standard of the subject's natural state. The purpose is to provide such a perimeter.
以下図面を参照し実施例に基づいて本発明を説明する。The present invention will be described below based on embodiments with reference to the drawings.

被検者の規準４はかかる状態でドームの固視指定位置５
に全く拘束されることがない。FIG. 1 is an explanatory diagram showing a perimeter according to the present invention. There is a face holder 1 and a forehead holder 2 for fixing the subject's head. The dome 3 is arranged so as to move independently of these face and forehead rests. Criterion 4 for subjects whose head is fixed due to face alignment and forehead rest is the fixation designated position 5 of the dome in such a state.
is not restricted at all.

。Next, although not shown in the figure, this perimeter is equipped with an observation system for monitoring the standard of the eye to be examined. The observation system consists of an optical system such as a telescope placed in the center or side of a dome, but the structure is not limited as long as it has the function of monitoring the criteria of the eye to be examined. A feature of the present invention is that a dome moving device 6 is provided for moving the dome back and forth, left and right, or up and down in order to align the designated fixation position 5 of the dome 3 with the monitored reference 4.

ものであること−が多い。The moving device 6 according to this example includes an arm 6 protruding from the dome 3.
It has an operation lever 6b that moves the a back and forth, left and right, and an operation knob that moves it up and down, so that it can be moved electrically in any direction or distance, but the mechanism of the device is not limited, and it can be operated manually, etc. There is no problem with the adoption of the above. Usually, the range of movement of the dome is often only a slight adjustment with respect to the standard.
本発明は以上の構成に基づくものであるから、ドームを

であって、強制的な同視の持続に基づく被検者の疲労が
軽減され視野計測データの信頼性が格段に向上し、また
検者側の負担も軽くなる等多くの利点を有するもので極
めて有用な発明である。Since the present invention is based on the above configuration, the dome is fixed and the eye of the subject is similarly fixed relative to the specified fixation position, and the visual field is continued to be measured while matching the standard. Unlike the Noyashikata method, the present invention attempts to match the dome's designated eye position by moving the dome to the standard of the subject's eye, which is fixed. This is an extremely useful invention as it has many advantages, such as reducing the fatigue of the examinee due to continuous visual aperture, greatly improving the reliability of visual field measurement data, and reducing the burden on the examiner. .
