EYE DROP MONITORING DEVICE AND METHOD

An eye drop monitoring device for monitoring gravity-driven placement of an eye drop into an eye of a patient includes a light source configured to selectively direct light toward at least one of the eye and the eye drop. The light is backscattered by at least one of the eye and the eye drop. A ligh...

Beschreibung
Zusammenfassung:	An eye drop monitoring device for monitoring gravity-driven placement of an eye drop into an eye of a patient includes a light source configured to selectively direct light toward at least one of the eye and the eye drop. The light is backscattered by at least one of the eye and the eye drop. A light detector is configured to detect the backscattered light from at least one of the eye and the eye drop and responsively produce at least one backscatter signal. An accelerometer is configured to determine a spatial position of the device and responsively produce a device position signal. A processing unit is configured to receive the at least one backscatter signal and the device position signal and responsively produce a drop-on-target signal indicative of a likelihood that the eye drop fell into a predetermined position with respect to the eye.
