Abstract
A device useful for making retrobulbar injections includes an inner syringe contained within an outer syringe. A spring retained within the outer syringe biases the inner syringe proximally, which a catch mechanism on the two syringes prevents the inner syringe from moving out of the outer syringe. A distal needle on the inner syringe is movable within a distal sheath of the outer syringe, and can be extended beyond the distal end of the sheath to permit the device to piece more resilient tissues, and can be withdrawn by action of the spring within the sheath to protect more delicate tissues from the needle.
