Abstract
An ophthalmic illumination and imaging system with transscleral/transpalpebral illumination of the eye fundus comprises a light-delivering device with a plurality of emitting areas; each of the emitting areas being configured to be independently controllable and directed towards the sclera of the intended eye to measure, providing transscleral oblique illumination of the eye fundus; an active eye aberration correcting system; and an imaging system configured to create multiple images of the eye fundus on multiple imaging sensors.
Claims20
An ophthalmic illumination and imaging system with transscleral/transpalpebral illumination of the eye fundus, the system comprising:
- a light-delivering device with a plurality of emitting areas;
- each of the emitting areas being configured to be independently controllable and directed towards the sclera of the intended eye to measure, providing transscleral oblique illumination of the eye fundus;
- an active eye aberration correcting system;
- and
- wherein the system further comprises an imaging system configured to create multiple images of the eye fundus on multiple imaging sensors, said multiple sensor comprising a first retinal camera imaging the retina of the intended eye to measure with high resolution and a second retinal camera imaging said retina over a field of at least about 30°, wherein
- the system further comprises:
- an active tracking system configured to track a movement of the eye fundus and configured to spatially stabilize at least one of the multiple eye fundus, wherein a measure of the movement of the eye is made using at least one of the multiple eye fundus images, wherein the correction of the eye movement is made using a 2-axis tip/tilt platform supporting the full wavefront corrector with an external rotation stage, or wherein the correction of the eye movement is made using a 2-axis tip/tilt platform supporting a mirror which does not include the wavefront corrector.
The system according to 1, wherein the retinal camera is configured to image the retina with a digital sampling of 20 μm/pixel.
