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.

The present invention relates a specific tetrahydroisoquinoline compound which is useful as a chemokine receptor type 3 (CCR3) antagonist, and a pharmaceutical composition comprising the same as an active ingredient. The tetrahydroisoquinoline compound of the present invention is useful for the treatment or prevention of a disease in which CCR3 participates.

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.

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.

An imaging apparatus includes an apparatus body having an outer casing, at least a shutter mechanism and an imaging device placed inside the outer casing, an opening formed in the outer casing, and a storage space and a placement space defined inside the outer casing and communicating with the opening and the storage space, respectively, a strobe unit having a lid part and a light-emitting part and connected to the apparatus body so as to be movable between close and open positions, a sensor unit placed in the placement space and having an autofocus sensor and a sensor adjusting part having plural adjusting screws, and a mirror placed inside the outer casing to reflect part of incident light toward the autofocus sensor. When the strobe unit is moved to the open position, the storage space is defined as an adjustment space into which an adjustment jig can be inserted.

When assessing the start time of the limulus reaction between biogenous biologically active substances and LAL and using the reaction start time to determine the concentration of the biogenous biologically active substances, in order to exclude the influence of progressive changes which occur regardless of the conditions of the limulus reaction, the strength of transmitted light or scattered light in the liquid mixture of the measurement sample and LAL is detected, the variation (delta) in the transmittance or number of gel particles is acquired at set intervals, and the time when the variation (delta) crosses a threshold value is taken as the reaction start time. Furthermore, the time intervals when acquiring the abovementioned delta are not uniform, and either change over time from the start of measurement as defined by a time function, or multiple sequences with differing time intervals are prepared in advance.

An imaging apparatus includes: a mount fixing member to which a lens mount is fixed; a connected body obtained by integrally connecting a plurality of constituent units including a battery holder unit, the plurality of constituent units provided around the mount fixing member; and a front member fixed to the connected body and integrated therewith, wherein the mount fixing member is fixed to the front member.
摘要:
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.
