Angioid streaks (Pseudoxanthoma). Ophthalmoscope view of the retina of a patient,showing angioid streaks. Here,red retinal blood vessels are seen entering the retina from the yellow optic disc (centre right). Beneath these blood vessels are dark,wavy,branching striae known as angioid streaks. These are actually breaks in the membrane at the back of the eye,due to a collagen disorder known as Pseudoxanthoma elasticum (PXE). PXE is a chronic skin disease producing yellow patches and stretching on the skin. There is degeneration of the elastic coat around arteries and,as here,the retina commonly develops angioid streaks. The condition may lead to loss of sight | |
