is not transmitted. Furthermore, since the optical stimulation electrode device does not have a light source section (5), it can be constructed to be lightweight and small, thereby reducing the burden when attached to the eyeball (1).

、眼球揺動による検出信号の変動を防止出来る。Furthermore, it is possible to provide a light source (14) for fixation, which is always turned on, separately from the light emitting element group (5a) in the light source section (5). This light source (14) can be composed of a light emitting element such as an LED, but the color of the emitted light is determined by light stimulation (3) on the retina (2).
For example, red light is preferable because the light is weak. However, the light emission intensity is extremely small compared to the emission weakness of the light emitting element group (5a) that provides optical stimulation (3).
In measuring RG, when the contact lens (4) is attached to the eyeball (1), the focus of the eyeball (1) is not determined and the eyeball (1) moves vertically and horizontally, and the ERG detection waveform changes accordingly. As a result, the baseline of the recorded waveform fluctuates, making accurate recording impossible. As mentioned above, a weak light source (1
4) in the light source section (5), this fixation light source (1)
4) Since it is possible to stop the movement of the eyeballs by staring at the object, it is possible to prevent fluctuations in the detection signal due to eyeball movements.

る充分な電気的応答が得られる。Furthermore, when a small point light source such as an LED is used as the light emitting element group (5a), or when using an optical fiber, the light source is small and the light stimulation (3) is applied to the entire retina (2). There was a difficult problem. Therefore, as shown in FIG. 4A, the surface of the contact lens (4a) facing the optical fiber (11) is made into a ground glass shape, or an opaque opalescent film is pasted to form a diffusing portion (15). It is possible to diffuse the light transmitted through the fiber (11) by the diffusing section (15) so that the optical stimulus to the retina (2) becomes diffused light. In addition, as shown in Figure 4B, contact lenses (4b
) itself into a concave lens structure, it is possible to apply optical stimulation (3) to the entire retina (2), and a sufficient electrical response can be obtained for the optical stimulation (3).

Various modifications can be made without departing from the gist of the present invention without being limited to the embodiments of the child series, such as being able to be used as a normal electrode.
