    • A perimeter has fixation state judging means for individually judging a fixation state of an examinee in connection with each presented stimulus, and the fixation state judging means individually judges the fixation state whenever the stimulus is presented. Even if defective fixation is judged, retest is conducted on only a point where the stimulus was presented, which was judged to be defective fixation. Then, examiner's burden and examinee's burden can be lightened, the test time can be made shorter and test efficiency can be improved in comparison with a case where the whole test is retried from the first as a conventional way.

    • A stimulus light from a stimulus light source is projected to the retina of an ocular fundus under examination to stimulate the retina in localized fashion to generate a bioelectric signal from the retina. The stimulus light source is mounted on a movable block, and an operating lever is used to move the stimulus light source to change the stimulus light on the retina. The size of the stimulus light can also be varied using a panel having a plurality of openings with different diameters for allowing the stimulus light to pass through. This assures a reliable local ERG examination because the bioelectrical signal can be produced in a wider area of the retina. The operating lever is further fixed by inserting a cap to keep the projected stimulus light unchanged. This allows the burden on the examiner to be reduced remarkably, assuring a reliable local ERG examination.
    • 来自刺激光源的刺激光被投射到正在检查的眼底视网膜,以局部方式刺激视网膜以从视网膜产生生物电信号。 刺激光源安装在可动块上,操作杆用于移动刺激光源以改变视网膜上的刺激光。 刺激光的尺寸也可以使用具有不同直径的多个开口的面板来改变,以允许刺激光通过。 这确保了可靠的局部ERG检查,因为生物电信号可以在视网膜的更广的区域中产生。 通过插入盖子来进一步固定操作杆,以保持投影的刺激光线不变。 这样可以显着降低审查员的负担,确保当地的ERG检查可靠。

    • 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.

    • [Problem] To increase, compared to conventional devices, the range of motion of the light emitter (fixation lamp) in an external fixation lamp for an ophthalmological instrument and allow movement of the light emitter to arbitrary positions.[Solution] The fixation lamp (1) has a first arm (A1), which supports a light emitter (2) and is supported by a second arm (A2) via a first joint (C1), and is configured so that the first arm (A1) is able to revolve around at least two axes of revolution (E1, E2) by means of the first joint (C1) and said axes of rotation (E1, E2) are not disposed on the same line. Thereby, the range in which the light emitter (2) can be moved can be increased compared to conventional devices and the light emitter can be moved to an arbitrary position in an arbitrary direction.

    • A color perception test has a color matching processor that executes a color matching processing on a color monitor, and an image display controller that displays two or more images for color perception test in order on the color monitor on which the color matching processing was done. When displaying each image for color perception test, a color perception test is done in a state that one of its hue, brightness, saturation and display time is changed and the other elements are fixed. Since the color perception tester has the color matching processor, colors of the image are not changed with passage of time different from color printed one, and correct test can be done thereby. If the test is periodically done on some examinee, a degree of decreasing color perception function by aging can be exactly known.
    • 颜色感知测试具有在颜色监视器上执行颜色匹配处理的颜色匹配处理器,以及在进行颜色匹配处理的彩色监视器上依次显示用于颜色感知测试的两个或更多个图像的图像显示控制器。 当显示每个图像的颜色感知测试时,颜色感知测试在其色调,亮度,饱和度和显示时间之一改变并且其他元素是固定的状态下完成。 由于颜色感知测试仪具有颜色匹配处理器,所以图像的颜色不会随着时间的推移而不同于彩色印刷,因此可以进行正确的测试。 如果在一些考生周期性地进行测试,则可以准确地知道通过老化降低颜色感知功能的程度。
