1. A method comprising: receiving optical coherence image data; and assessing functional glaucoma damage from the retinal optical coherence image data, wherein assessing functional glaucoma damage comprises: measuring at least a portion of an abnormal Retinal Ganglion Cell Axonal Complexes (RGC-AC), wherein measuring at least a portion of the RGC-AC includes approximating a connection trajectory of a nerve fiber bundle between a specific retinal location and a head of an optic nerve, and, analyzing structural indices associated with at least one or more discrete ocular regions.
