1. A laser treatment method for an eye, the eye having an optical axis, a pars plana posterior to a pars plicata and a pre-laser treatment intraocular pressure, the method comprising:
positioning a probe in contact with an outer surface of a sclera of the eye so that a laser energy delivery tip of the probe is oriented transverse to the outer surface of the sclera toward the pars plana of the eye to define a treatment axis that is angularly offset from the optical axis of the eye;
directing laser energy from the oriented laser energy delivery tip of the probe to the pars plana of the eye to a first application site in a target region; and
repositioning the probe and directing laser energy to a plurality of additional application sites in the target region while maintaining an orientation of the probe at each application site so that the laser energy delivery tip is transverse to the outer surface of the sclera with the treatment axis angularly offset from the optical axis of the eye;
wherein an aggregate amount of laser energy is sufficient to maintain a reduction from the pre-laser treatment intraocular pressure.
