Microperimetry and SD-OCT data of right eye patient 14 with SS sickle cell disease and no focal thinning (Group B, BCVA 20/20). (Top Left) Microperimetry Polar 3 test grid superimposed on the SLO infrared image. Small white crosses indicate fixation. Each value represents the light sensitivity for the corresponding retinal area. Based on normative data for this particular instrument, a sensitivity of > 12 dB was considered normal. Note that all data points are > 12 dB in this patient. (Top Right) Corresponding SD-OCT thickness (μm) at each of the 28 Polar 3 tested points showing no macular thinning. (Bottom) SD-OCT B-scan image also showing no focal macular thinning.
