摘要：
An apparatus (410) for delivering therapeutic agent to an eye comprises a body (440), a cannula (420), a hollow needle (430), a cannula actuation assembly (500), and a needle actuation assembly (550). The cannula extends distally from the body and is sized and configured to be insertable between a choroid and a sclera of a patient's eye. The cannula actuation assembly is operable to actuate the cannula relative to the body. The needle actuation assembly is operable to actuate the needle relative to the cannula. The cannula may be inserted through a sclerotomy to position a distal end of the cannula at a posterior region of the eye, between the choroid and sclera. The needle may be advanced through the choroid to deliver the therapeutic agent adjacent to the potential space between the neurosensory retina and the retinal pigment epithelium layer, adjacent to the area of geographic atrophy.
