| 20100253910 | Ocular light stimulus apparatus - An ocular light stimulus apparatus is proposed in which an ocular fundus of an examinee's eye is illuminated by infrared light from an illumination light source via a ring slit disposed in the position conjugate with the anterior ocular segment thereof, and the ocular fundus is irradiated with stimulus light from a stimulus light source and background light from a background light source via a photographic stop disposed in the position substantially conjugate with the anterior ocular segment of the examinee's eye. This allows the background light to be projected onto the ocular fundus so as to spread in all directions about the center of the anterior ocular segment. Therefore, the entire ocular fundus can be uniformly illuminated about the position onto which the stimulus light is projected, and an accurate local ERG examination can be performed. Since the ocular fundus is irradiated with the background light and the stimulus light via the center part of the pupil, shading does not occur even when the pupil diameter is somewhat small, and the amount of the background light and the stimulus light can be kept constant regardless of the pupil diameter, ensuring a highly reliable local ERG examination. | 10-07-2010 |
