WebSpectral domain OCT (SD-OCT) offers high-resolution imaging of the retinal layers, allowing a detailed analysis of the morphology of ODP-M, and may detect small areas of outer retinal dehiscences missed on TD-OCT imaging. We describe a case of ODP-M with a small area of outer retinal dehiscence that was revealed on SD-OCT. WebOptical coherence tomography (OCT) is a non- invasive optical imaging technique that uses low-power infrared laser light to image up to 2 mm beneath the skin surface. The clinician can obtain real-time images of the architecture of the skin without pretreatment or gels.
