A 66-year-old presented with complaints of “greying” of vision. What pathology is noted?

Tip #102

Analysis

The left of the image is within normal limits. Here you can easily see the nerve fiber layer (NFL) and ganglion cell (GC) layers. Moving to the outer layers, the plexiform and nuclear layers are also within normal limits. In the center of the image the external limiting membrane (ELM) becomes lost and the outer nuclear layer is thinned. The ellipsoid layer (EL) is fragmented and lost centrally and there is hyperreflective lesions in the deep retina (this represents RPE retinal migration). These spots are associated with shadowing. There is also the presence of both inner and outer retinal cysts.

This patient was diagnosed with MacTel (also referred to as juxtafoveal or parafoveal telangiectasis).

OCT Tip

In a patient with both inner and outer retinal cysts and loss of the outer retina, MacTel should be considered. This is especially true if associated with significant hyperreflectivity.
