This 70YO female presented with mild vision loss in her left eye. Vision was 20/50.
Optos imaging shows a retinal arterial macroaneurysm (RAM) with surrounding blood. Swept-source OCT shows the hyperreflective RAM in the inner retina. The underlying retina is somewhat thickened.
Learning Points:
A RAM is thought to occur in a weakened arterial wall from arteriosclerosis, and usually appears as a yellow-white dilated lesion along a retinal arteriole within the first 3 bifurcations from the optic nerve.
Although most RAMs spontaneously resolve, chronic central edema or lipid can cause long term vision loss.
Mansour et al, Retina 2019;39;1133-1141, showed that anti-VEGF treatment is effective in reducing macular exudation and improving vision.
