Abstract: A device for removing a thrombus from a retinal vessel has a grip held by the user of the device, a tubular portion to be inserted into the eye, the tubular portion being provided at an end of the grip, a microtube to be inserted into a retinal vessel, the microtube being provided at an end of the tubular portion, a linear pusher axially slidably held in the microtube and the tubular portion, and an operating portion provided at the grip. The linear pusher is adapted to protrude to a desired position from an end of the microtube by axially sliding the linear pusher by means of the operating portion, thereby the linear pusher physically pushes a thrombus out of the retinal vessel.
