Abstract

It is important to make a differential diagnosis between drusen and the presence of any retinal hard exudates which are diabetic in origin. One of the most frequently detected abnormal retinal features are drusen. The normal adult human eye possesses usually unobservable superficial retinal nerve fibres, connecting the photoreceptors ultimately to the visual cortex. Retinal nerve fibres, unlike those within the optic nerve itself, are usually devoid of a myelin sheath. On examination, myelinated nerve fibres (MNFs) can be seen as highly reflective whitish-yellow opaque patches surrounding the optic disc with marked striations. The correct identification of patches of MNF is important in order to differentiate these from cotton wool spots, hard exudates and, in some cases, even retinal oedema. Coats' disease is an idiopathic retinal telangiectasia first described by the Scottish ophthalmologist George Coats in 1908.
