Concentric "microwaves" of Henle's fiber layer: associated with horizontal folding.
Concentric "microwaves" in Henle's fiber layer are found in a case of extensive horizontal folding in the fundus due to tumor pressure on the globe from behind. In addition to horizontal folding of inner choroid and inner retina between disk and fovea, somewhat irregular vertical folds are found next to the fovea in the inner retinal layers. The concentric waves of Henle's fiber layer are a new observation and they are suspected to be a protective adjustment of the central retina to minimize distortion of the foveola.
