Photoreceptor Impairment and Restoration on Optical Coherence Tomographic Image

Figure 5

Spectral-domain optical coherence tomographic (SD-OCT) image of an eye 3 weeks after macular hole repair (72-year-old woman). SD-OCT image of a vertical scan was obtained. In addition to photoreceptor inner/outer segment (IS/OS) junction line, the external limiting membrane (ELM) and cone outer segment tips (COST) lines are clearly seen on the SD-OCT image. Red arrows indicate end points of the COST line. White arrows indicate end points of the IS/OS line. The ELM line has been almost restored. Note that the defect length was longest in the COST, followed by the IS/OS and ELM. The direction of photoreceptor restoration is from inside toward outside.
