Abstract
In some embodiments, readily understandable information displays are provided to help an operator guide an eye of a subject into an eyebox of a retinal imaging system. In some embodiments, a three-dimensional position of the eye with respect to the retinal imaging system is determined, and an interface that includes a three-dimensional representation of the position of the eye with respect to the eyebox is generated. In some embodiments, the gaze direction may also be determined and presented in the interface, so that the operator can also prompt the subject to correct issues with incorrect gaze direction.
Claims17
A non-transitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by one or more processors of a computing device, cause the computing device to perform actions for guiding an eye into a desired position in relation to a retinal imaging system, the actions comprising:
- receiving, by the computing device, position information that includes a first indication of an actual position of the eye in relation to the retinal imaging system and a second indication of a gaze direction of the eye;
- determining, by the computing device, a difference between the actual position of the eye and the desired position of the eye in relation to the retinal imaging system;
- and
- generating, by the computing device, a display interface that includes a first representation of the desired position of the eye and a second representation of the actual position of the eye to aid in reducing the difference between the actual position of the eye and the desired position of the eye, wherein the display interface further includes a third representation indicating the gaze direction or a gaze location of the eye.
A retinal imaging system, comprising:
- an eyepiece;
- an alignment tracker configured to collect information regarding a three-dimensional position of an eye with respect to the eyepiece;
- and
- a controller computing device configured to:
- receive position information from the alignment tracker that includes a first indication of an actual position of the eye in relation to the eyepiece of the retinal imaging system and a second indication of a gaze direction of the eye;
- determine a difference between the actual position of the eye and a desired position for the eye in relation to the eyepiece when imaging a retina of the eye;
- and
- generate a display interface that includes a first representation of the desired position and a second representation of the actual position of the eye to aid in reducing the difference between the actual position of the eye and the desired position, wherein the display interface further includes a third representation indicating the gaze direction or a gaze location of the eye.

- and
- generate a display interface that includes a first representation of the desired position and a second representation of the actual position of the eye to aid in reducing the difference between the actual position of the eye and the desired position, wherein the display interface further includes a third representation indicating the gaze direction or a gaze location of the eye, wherein the third representation indicates where the eye is currently gazing relative to a fixation target.
