OCT Academy - Tip of the Week (previous)

142. Blurring in a 76-year-old

This 76-year-old noted blurred vision for 3 weeks. Why?

Tip #142


In this image of the left eye, there is fluid located in the inner nuclear and outer plexiform layers. There are focal areas of hyper reflectivity consistent with exudation. The patient also has collaterals (A).

The patient was diagnosed with a retinal vein occlusion.

In this tip's accompanying 20 min. video, Dr. Sharma takes you through additional diagnostic imagery as well as:

  • Review this OCT b-scan image using The NOERC Method
  • Discuss a practical differential diagnosis for hyperreflectivity as it applies to this image
  • Review the work of Kim et al on collaterals related to RVO and OCTA
Tip #142 Analysis


Superficial reflectivity may be a related to the presence of collateral vasculature formation.
