Figure 3. Spectral-domain optical coherence tomography (SD-OCT) findings of the eyes in normal controls (A, B) and in this case (C-F). Images from right eyes (C, D) and left eyes (E, F) are shown. Images at lower magnification (A, C, E) and higher magnification (B, D, F) are shown. The SD-OCT findings for the eyes in this case show obvious blurring of the IS/OS junction and the COST line. The COST line disappeared in the peripheral macula area in this case.
