Abstract
An OCT appliance (optical coherence tomography appliance) comprises an OCT module and a camera for observing the fundus of an eye. By recognizing characteristic features (biometric features), the means defining the region observed by the OCT module, in particular the scanner of the OCT module, is adjusted so that a predefined region of interest is imaged by the OCT module. In preferred embodiments, the apparatus is apt to be operated by a patient himself, and the data are transferred to a clinical server so that a more frequent, hence closer observation of the eyes of the patient is possible.
Claims29
An ophthalmologic appliance for imaging a retina of an eye fundus, the appliance comprising:
- an optical coherence tomography arrangement;
- a camera configured to take an image of the fundus of the eye sufficient to determine a location of characteristic features of the fundus;
- and
- a director positioned and configured to adjust the arrangement so as to aim automatically at least one observation region of the retina based on a spatial relation between the at least one observation region and the location of the characteristic features of the fundus determined from the image, wherein the camera is a low resolution fundus camera having a resolution of at most 5 lp/mm.
An ophthalmologic appliance for imaging a retina of an eye fundus, the appliance comprising:
- an optical coherence tomography arrangement;
- a camera configured to take an image of the fundus of the eye sufficient to determine a location of characteristic features of the fundus;
- and
- a director positioned and configured to adjust the arrangement so as to aim automatically at least one observation region of the retina based on a spatial relation between the at least one observation region and the location of the characteristic features of the fundus determined from the image, wherein the camera has a resolution of at most 7 pixels per degree of field of view.
An ophthalmologic appliance for imaging a retina of an eye fundus, the appliance comprising:
- an optical coherence tomography arrangement;
- a camera configured to take an image of the fundus of the eye sufficient to determine a location of characteristic features of the fundus;
- and
- a director positioned and configured to adjust the arrangement so as to aim automatically at least one observation region of the retina based on a spatial relation between the at least one observation region and the location of the characteristic features of the fundus determined from the image, wherein the appliance is binocular and configured to secure a reproducible position before eyes of a patient, and wherein the appliance is configured to be adjustable for a person by adjusting at least the interpupillary distance and view properties of the person's eyes, and the appliance comprising a locking unit positioned and configured to lock an adjusted position or to store or to restore the adjusted position.
