1. A system for treating ophthalmic target tissue using a treatment pattern of lesions, wherein the treatment pattern comprises a first sub-pattern of lesions and a second sub-pattern of lesions, the system comprising: a light source for generating a beam of light towards a beam delivery unit; the beam delivery unit configured to deliver the beam of light to the ophthalmic target tissue, the beam delivery unit including a scanner unit configured to deflect the beam of light; and a control unit operatively coupled to and configured to control at least one of the light source and the beam delivery unit to: deliver the beam of light to the ophthalmic target tissue, wherein the delivery creates a first sub-pattern of lesions on the ophthalmic target tissue, the first sub-pattern including: a plurality of ophthalmoscopically invisible lesions, and at least one ophthalmoscopically visible lesion; and a visualization device configured to identify an ophthalmoscopically visible lesion from the first sub-pattern of lesions, wherein the control unit is further configured to control a least one of the light source and the beam delivery unit to: after creating the first sub-pattern, align the beam of light based on the identified ophthalmoscopically visible lesion from the first sub-pattern, and create the second sub-pattern of lesions on the ophthalmic target tissue using the aligned beam of light, wherein the ophthalmoscopically visible lesion from the first sub-pattern indicates an end of the first sub-pattern, and wherein the second sub-pattern is adjacent the first sub-pattern but does not overlap the first sub-pattern.
