17. A system to treat glaucoma of an eye, the system comprising:
an energy source;
a processor configured with instructions to direct energy to a plurality of treatment locations of the eye, the plurality of treatment locations located at least 2 mm radially outward from a limbus and corresponding to an angle within a range from 30 degrees to 360 degrees around a sclera of the eye;
a handpiece coupled to the energy source and the processor, the handpiece comprising:
an eye contacting surface to couple to the eye and
a plurality of energy releasing elements disposed at a plurality of handpiece locations to release energy to the eye at the plurality of treatment;
wherein the handpiece is configured to deliver the energy to the plurality of treatment locations in order to open an iridocorneal angle of the eye by an amount within a range from 0.5 degrees to 10 degrees;
wherein the eye comprises a human eye and the plurality of treatment locations correspond to a surface area on the sclera, and wherein the surface area is within a range from 1 mm2 to 100 mm2 and wherein the surface area is located radially outward from the limbus on a sclera of the eye by at least 2.5 mm and anterior to a lens equator on the sclera of the human eye and wherein the iridocorneal angle opens in response to the plurality of treatment locations and wherein the plurality of treatment locations is located anterior to the lens equator by no more than 3 mm.
