Hollenhorst plaques in diabetic retinopathy screening

Hollenhorst plaques are described as orange/yellow plaques at bifurcations of the retinal arterioles. Papers and textbook descriptions have largely followed this original description of cholesterol emboli but it has been suggested that emboli may damage the vessel wall, producing a sheathing reaction.

The aim was to clarify the use of the term Hollenhorst plaque when used in the local diabetic eye screening programme.
