Abstract: Sensing systems, devices and methods are disclosed for determining the relative movement of first and second members of a medication delivery device which are proportional to the amount of a dose set and/or delivered by operation of the medication delivery device. A sensor is coupled with the first member. A pair of targets is coupled with the second member. Each target comprises an array of teeth which move through an area sensed by the sensor. The sensor thereby detects characteristic values of a sensed parameter corresponding to the combined relative positions of the first and second members. The sensing system outputs this information to a processor which determines the amount of the dose set and/or delivered. Related medication delivery devices and methods are also disclosed.

Abstract: A method includes inserting a flexible cannula between a sclera and a choroid of an eye. The needle is advanced from a distal end of the flexible cannula, such that the needle pierces the choroid to access a subretinal space of the eye.
