OPHTHALMOLOGIC MICROSCOPE WITH MICRO-MIRROR BALANCING
20230049486 · 2023-02-16 · ·

The ophthalmologic microscope has an illumination device for projecting light onto an eye to be observed and a microscope device with a camera to view the eye. The illumination device generates pulsed light. The light is pulsed at least at twice the frame rate of the camera to reduce flicker. The illumination device uses an array of micro-mirrors as spatial light modulator, and the mirrors are controlled for a balanced deflection over the frame cycles, which allows to increase the service life of the microscope.

SYSTEMS AND METHODS FOR PERIPHERAL RETINAL OPTICAL COHERENCE TOMOGRAPHY
20230053244 · 2023-02-16 ·

Peripheral retinal OCT can be used to generate peripheral retinal OCT images allowing for the peripheral retina to be viewed. A peripheral retinal vision system can determine that a set of fiducial markers is in a field-of-view of at least one camera and record positional data comprising a contact lens position and angle with respect to an OCT imaging system having OCT scanning mirrors in a first position. The system can determine whether a retinal layer is in an OCT scan captured while the set of fiducial markers is in the field-of-view of the at least one camera and the OCT scanning minors are in the first position; and for an OCT scan having he retinal layer and being captured while the set of fiducial markers is in the field-of-view of the at least one camera and the OCT scanning minors are in the first position, store that OCT scan.

Systems And Methods For Optical Evaluation Of Pupillary Psychosensory Responses
20230052100 · 2023-02-16 ·

The present disclosure is directed to systems and methods for measuring and analyzing pupillary psychosensory responses. An electronic device is configured to receive video data with at least two frames. The electronic device then locates one or more eye objects in the video data and determine pupil and iris sizes of the one or more eye objects. The electronic device determines the pupillary psychosensory responses of the one or more eye objects by tracking a ratio of pupil diameter to iris diameter throughout the video. Several metrics for the pupillary psychosensory responses can be determined (e.g., velocity of change of the ratio, peak to peak amplitude of the change in ratio over time, etc.). These metrics can be used as measures of an individual's cognitive ability and mental health in a single session or tracked throughout multiple sessions.

Determining the Risk of Opioid-Related Adverse Events Based on Pupillary Measurements
20230053166 · 2023-02-16 ·

The disclosure provides methods of managing opioid therapy, particularly, for pain management. The methods comprise determining in a subject, for example, a subject who has received an opioid treatment, pupillary unrest in ambient light (PUAL). Low values of PUAL can be used to identify patients at risk for opioid side-effects, such as opioid-related respiratory depression (OIRD), and who warrant attention to prevent such side effects. Accordingly, the methods include monitoring the patients having low values of PUAL for signs of adverse side-effects and/or limiting or avoiding administration of opioids.
