摘要: Ophthalmic imaging systems, particularly slit-scanning ophthalmo-scopes, are capable of characterizing refraction over the entire field of view of the system. Light from the light source of the system illuminates a region of the eye and the returning light is measured on a detector. The deviation of the location of the returning light from a predetermined location on the detector is measured. The deviation corresponds to the mismatch between the refractions of the imaging system and the eye. The light can be scanned across the full field of view to characterize the entire field. A second illumination source traveling along a second illumination path can be used to improve the characterization. The characterization can be of use for optimizing the focus of the instrument and for assessing the condition of the eye, including assessing myopia and astigmatism in the periphery.

摘要: An ophthalmic imaging system provides an automatic focus mechanism based on the difference of consecutive scan lines. The system also provides of user selection of a focus point within a fundus image. A neural network automatically identifies the optic nerve head in an FA or ICGA image, which may be used to determine fixation angle. The system also provides additional scan tables for multiple imaging modalities to accommodate photophobia patients and multi-spectrum imaging options.

摘要: Imaging systems are provided allowing examination of different object regions spaced apart in a depth direction by visual microscopy and by optical coherence tomography. An axial field of view and a lateral resolution is varied depending on which object region is examined by the imaging system. The proposed imaging systems are in particular applicable for thorough examination of the human eye.

摘要: The present application describes the addition of various feedback mechanisms including visual and audio feedback mechanisms to an ophthalmic diagnostic device to assist a subject to elf align to the device. The device may use the visual and non-visual feedback mechanisms independently or in combination with one another. The device may provide a means for a subject to provide feedback to the device to confirm that an alignment condition has been met. Alternatively, the device may have a means for sensing when Acceptable alignment has been achieved. The device may capture diagnostic information during the alignment process or may capture after the alignment condition has been met.

摘要: The present application describes the addition of various feedback mechanisms including visual and audio feedback mechanisms to an ophthalmic diagnostic device to assist a subject to self-align to the device. The device may use the visual and non-visual feedback mechanisms independently or in combination with one another. The device may provide a means for a subject to provide feedback to the device to confirm that an alignment condition has been met. Alternatively, the device may have a means for sensing when acceptable alignment has been achieved.
