摘要:
A device for monitoring eye movement and pupil response that comprises a first optical pathway for displaying one or more images to the eyes of a patient and a second optical pathway for obtaining images of the eyes of a patient. The device further comprises at least one screen for displaying an image to the left eye of the patient which is not visible to the right eye of the patient and for displaying an image to the right eye of the patient which is not visible to the left eye of the patient; a first camera for capturing images of the left eye of the patient; and a second camera for capturing images of the right eye of the patient at substantially the same time as the first camera is capturing images of the left eye of the patient. The device also comprises at least one IR light source for illuminating the eyes of the patient; and a processor for processing the obtained images and measuring pupil response and/or eye movements.
摘要:
An ocular fundus camera system and an associated methodology. The system includes (a) an image sensor disposed along a fundus-image reflection path adjacent that path's downstream end, and in optical communication with light carried in this path, (b) an aperture centered on the reflection path's long axis, operatively associated with, and stationary with respect to, the sensor at a location which is upstream from the sensor, and (c), for accomplishing (1) precision fundus-image focusing on the sensor, and additionally (2) autorefraction, optical, light-content shifting structure, operable selectively for producing, within that portion of the reflection path which is disposed downstream from the shifting structure, relative trans-axial displacement solely of any non-collimated light carried in that portion of the main path which is disposed upstream from the shifting structure.
