Diabetic Cotton wool spots

Accumulations of neuronal debris within the nerve fibre layer. They result from disruption of nerve axons. As cotton wool spots heal, debris is removed by autolysis and phagocytosis.

Signs: Small, whitish, fluffy superficial lesions which obscure underlying blood vessels and are clinically evident only in the post-equatorial retina, where the nerve fibre layer is of sufficient thickness to render them visible

FA : shows focal hypofluorescence due to blockage of background choroidal fluorescence, frequently associated with adjacent capillary non-perfusion.
