Abstract
A target volume of ocular tissue of an irido-corneal angle of an eye is treated by moving a focus of a laser through the target volume of ocular tissue, and photodisrupting the target volume of ocular tissue at a plurality of spots as the focus is moved through the target volume of ocular tissue. The focus is moved by transverse scanning the focus between at least one of: a first circumferential boundary and a second circumferential boundary of the target volume of ocular tissue, and a first azimuthal boundary and a second azimuthal boundary of the target volume of ocular tissue, and axial scanning the focus between a distal extent and a proximal extent of the target volume of ocular tissue.
