Hollenhorst plaque with branch retinal artery occlusion causing a cherry red spot

Hollenhorst plaque with BRAO causing cherry red spot

Image Comments:

Cherry red spots classically occur after CENTRAL retinal artery occlusion (CRAO). The cherry red spot occurs because the choroidal and retinal circulation is separate. The richly vascularized sub-foveal choriocapillaris remains perfused after CRAO, but the surrounding retina becomes opaque due to edema as the tissue becomes ischemic. This was an interesting case in which a cholesterol (Hollenhorst) plaque became lodged in an inferior branch of the central retinal artery that perfused both the superior and inferior macula. Unfortunately for this patient this resulted in significant central vision loss.
