An elderly woman presented with metamorphopsia. Why?
Analysis
There is flattening of the surface of the retina indicating an area of vitreomacular adhesion. In the deep retina, there is elevation of the ellipsoid zone. There is also thickening of the outer nuclear layer. The subretinal space is infiltrated by an area of hyperreflectivity (SHRM - subretinal hyperreflective material). An OCTA was performed (video) which demonstrated a classic choroidal neovascularization (CNV).
The patient was treated for Wet AMD.
In this tip's accompanying 11 min. video, we'll review:
- The different types of CNV on angiography
- The causes of CNV
OCT Tip
Hyperreflectivity between the ellipsoid and RPE is called SHRM and is associated with CNV.
