Abstract
A system and process for treating retinal diseases includes passing a plurality of radiant beams, i.e., laser light beams, through an optical lens or mask to optically shape the beams. The shaped beams are applied to at least a portion of the retina. Due to the selected parameters of the beams—pulse length, power and duty cycle—the beams can be applied to substantially the entire retina, including the fovea, without damaging retinal or foveal tissue, while still attaining the benefits of retinal phototherapy or photostimulation.

1-28. (canceled)
A process for performing retinal photostimulation, comprising the steps of:
- generating a plurality of radiant treatment beams, wherein the radiant treatment beams comprise individual treatment beams having different predetermined parameters;
- and
- simultaneously applying the radiant treatment beams to the retina and/or at least a portion of the fovea, so as to effect photostimulation thereof;
- wherein the radiant treatment beams have a wavelength between 532 nm and 1300 nm, a duty cycle of less than 10%, an exposure duration of 500 milliseconds or less, and a power or intensity of 100 watts to 590 watts per square centimeter, to produce true subthreshold photocoagulation without permanently damaging the retinal or foveal tissue.
