Abstract: A method of at-home monitoring of eye conditions using a head mounted display that is capable of establishing a visual model associated with a patient. The visual model may include data related to a quality of the patient's vision. The patient may use the system to establish a visual model periodically, such as daily, and the system may compare the visual model to previous visual models and send an alert to the patient's physician if changes meeting a given criteria are detected. This may allow the physician to immediately take steps to save the patient's eyesight where a delay in treatment may result in vision loss.

The apparatus includes a stereomicroscope configured to obtain and display 2D or 3D image content of an eye of a patient, with pupil imaging optics that form a pupil along an optical axis and a shutter configured to form a pattern of one or more apertures for light at the formed pupil, and an input prism is configured to direct light to or from the optical axis, with optics configured to convey light along the optical axis to a sensor.

Abstract: Index creation in a streaming database with medical state parameters allows near-real-time access to medical state parameters reflecting medical states of patients. A message broker receives messages that include records with current measured medical state parameter values of patients. A stream processor processes messages with a plurality of parameter augmentation algorithms to derive additional computed medical state parameter values for a respective patient. Records with the computed values are inserted via generated messages into any incoming data stream. A data handler can create persisted patient-signal specific stream data tables for unknown combinations of patient identifier and signal identifier in the streaming database, and can create a block range index for the time information of the persisted stream data table.
