A system for providing a therapeutic treatment to a patient's eye, the system comprising: a treatment beam source configured to transmit a treatment beam along a treatment beam path; a scanning device disposed along the treatment beam path and configured to scan the treatment beam along ocular tissue of the patient's eye; and a processor coupled to the scanning device and configured to: A) define a plurality of target positions between first and second locations forming a 2 x 2 array and relative to the ocular tissue for the treatment beam, the plurality of target positions comprising a first position, a second position, and a plurality of intermediate positions; B) carry out a treatment cycle by scanning the treatment beam incrementally to each of the target positions between the first and second locations and deliver a pulse from the treatment beam onto the ocular tissue at each of the plurality of target positions to provide treatment spots at the target positions, wherein the treatment beam is fixed at each treatment spot while the treatment beam is delivered; and C) repeat the treatment cycle a plurality times to deliver, during each treatment cycle, an additional pulse from the treatment beam at each of the plurality of target positions; wherein a duration of each pulse is about 100 microseconds; wherein a time interval between pulses delivered in successive treatment cycles at each target position is about 1900 microseconds; and wherein a total number of pulses directed to each target position is sufficient to induce photoactivation of a therapeutic healing without forming a visible damage spot on the ocular tissue at that position; wherein the ocular tissue comprises retinal tissue. a treatment beam source configured to transmit a treatment beam along a treatment beam path; a scanning device disposed along the treatment beam path and configured to scan the treatment beam along ocular tissue of the patient's eye; and a processor coupled to the scanning device and configured to: A) define a plurality of target positions between first and second locations forming a 2 x 2 array and relative to the ocular tissue for the treatment beam, the plurality of target positions comprising a first position, a second position, and a plurality of intermediate positions; B) carry out a treatment cycle by scanning the treatment beam incrementally to each of the target positions between the first and second locations and deliver a pulse from the treatment beam onto the ocular tissue at each of the plurality of target positions to provide treatment spots at the target positions, wherein the treatment beam is fixed at each treatment spot while the treatment beam is delivered; and C) repeat the treatment cycle a plurality times to deliver, during each treatment cycle, an additional pulse from the treatment beam at each of the plurality of target positions; A) define a plurality of target positions between first and second locations forming a 2 x 2 array and relative to the ocular tissue for the treatment beam, the plurality of target positions comprising a first position, a second position, and a plurality of intermediate positions; B) carry out a treatment cycle by scanning the treatment beam incrementally to each of the target positions between the first and second locations and deliver a pulse from the treatment beam onto the ocular tissue at each of the plurality of target positions to provide treatment spots at the target positions, wherein the treatment beam is fixed at each treatment spot while the treatment beam is delivered; and C) repeat the treatment cycle a plurality times to deliver, during each treatment cycle, an additional pulse from the treatment beam at each of the plurality of target positions; wherein a duration of each pulse is about 100 microseconds; wherein a time interval between pulses delivered in successive treatment cycles at each target position is about 1900 microseconds; and wherein a total number of pulses directed to each target position is sufficient to induce photoactivation of a therapeutic healing without forming a visible damage spot on the ocular tissue at that position; wherein the ocular tissue comprises retinal tissue.
