Abstract
The procedures described herein may involve using one or more treatment beams to induce one or more therapeutic benefits. In some embodiments, a series of short duration light pulses may be delivered to ocular tissue at a plurality of target locations with a thermal relaxation time delay to limit the temperature rise of the target ocular tissue and thereby limit a thermal effect to only a desired portion of the ocular tissue. The thermal relaxation time delay may be roughly equivalent to a duration of a scan of the treatment beam between each of the target locations. Such procedures may be used to treat diabetic retinopathy, macular edema, and/or other conditions of the eye. The treatment beam may be delivered at each target location within a sufficiently short duration so as to produce a visual appearance of a treatment pattern on the ocular tissue of the patient's eye.
