1. A method for identifying a region of potentially reduced visual acuity in the eye comprising: obtaining a first set of measurements over a region associated with nerve fiber tissue in the eye, said measurements for characterizing the capacity or amount of the fiber tissue; obtaining a second set of measurements over said region associated with the nerve fiber tissue, said measurements for characterizing the orientation of nerve fibers or the orientation or position of anatomical features associated with the nerve fibers; determining from said first set of measurements at least one region of reduced tissue capacity or reduced amount of fiber tissue; identifying a region of potentially reduced visual acuity based on the location of the determined region of reduced tissue capacity or reduced amount of fiber tissue and an association between the second set of measurements and a map of fiber pathways; and displaying or storing information associated with the region of potentially reduced visual acuity.
