Devices and materials for treating an ophthalmic pathology affecting an eye of a patient comprising forming, in situ, a continuous cohesive layer of covalently-crosslinked hydrogel at a choroid in the eye, wherein the hydrogel comprises a therapeutic agent that is released into the eye to treat the ophthalmic pathology. An injection device for injection into a tissue, for example an eye, comprising a syringe, and a needle, with the syringe comprising a reservoir in fluid communication with an outlet and a piston for expelling contents of the reservoir from the syringe through the outlet. An embodiment provides for setting or using a force for moving the piston so as to deliver the contents at, for instance, a suprachoroidal location. |
