A 58-year-old with poor vision after being in bright light. Why?

Tip #182


The superficial retina is within normal limits. There is some degeneration of the external limiting membrane and the ellipsoid zone. The primary area of pathology is hyperreflectivity located at the level of the outer segments of the photoreceptors (COST line). This area corresponded to an 400 micron whitish lesion (video).

The patient was diagnosed with adult vitelliform foveo-macular dystrophy (AVFMD).

Tip #182 Analysis


Hyperreflectivity at the level of cost line caused by an elevation may represent a AVFMD.
