1. A method for monitoring patient-performed drug delivery from a hand-held container to a region of interest (ROI) associated with the patient's body, the method comprising: applying hand input to a drug-delivery system to squeeze a drop of said drug from a tip of the container and to release said drop from said tip, the drug-delivery system including the container containing said drug and a container-holding system having a first frame component structured to house the container therein along an axis thereof and a second frame component extending from the first frame component, the second frame component carrying an imaging camera having an optical field-of-view (FOV), an optical detector, and enabled to record images of a scene within the FOV, the FOV covering the tip, the ROI, and a space separating the tip from the ROI; recording a series of image frames, each frame representing a corresponding position of said drop in said space; and producing a report representing whether said drop landed in, partially in, or out of the ROI.
