    Diagnostic & Imaging, Glaucoma

    In this 1-Minute video, Dr. John Lind offers pearls for evaluating Cirrus OCT scans. Physicians should begin by assessing the retinal nerve fiber layer (RNFL) thickness map, which should ideally show butterfly wings with red spots to indicate adequate thickness. Next, the RNFL deviation map is examined for signs of thinning emanating from the superior and inferior poles of the optic nerve, which could indicate glaucomatous thinning. Finally, the RNFL thickness quadrants should be checked for overall thickness and left/right symmetry.
