April 2018 Image of the Month

Image of the Month, a recurring feature in Retinal Physician since 2006, spotlights diagnostic images captured by industry practitioners using innovative technology and diagnostic instruments.

Using SS-OCT to Image Through Sub-hyoidal Hemorrhaging



This case shows the beneļ¬ts of using Swept Source OCT technology when imaging through media opacities such as sub-hyoidal hemorrhaging.

Using the Topcon DRI Swept Source OCT’s 1050nm wavelength it is possible to image all the retinal layers of a 64-year-old male patient, as well as the choroidal structures through the hemorrhage while maintaining a clear imaging of the vitreal structures such as the posterior vitreous detachment and the hemorrhage beneath it. The ability to clearly image the choroid, even in cases with media opacities, is becoming increasingly important.

The upper images (A and B) show a fundus image (A) as well as a horizontal OCT (B) scan through a sub-hyoidal hemorrhage under a posterior vitreous detachment as well as through a much denser pre-retinal hemorrhage. The bottom images (C and D) show the same case using a vertical OCT scan.
