ABSTRACT:
This invention is a device for microvascular injection and a method for treating glaucoma using the device. The device comprises a reservoir attached to a blunted needle connected to a flexible tapered tubing, at the end of which is positioned a microneedle or micropipette for inserting into small blood vessels. The invention also provides a method for treating glaucoma and other diseases wherein microinjection of disease-ameliorating drugs into small blood vessels and their capillary beds would be therapeutically effective.
