Angioid Streaks are gray or brown lines that radiate out form the area around the optic nerve. PXE is an inherited disorder characterized by fragmentation and degeneration of elastic tissues within the skin, gastrointestinal tract, cardiovascular system, and the eyes with subsequent calcium deposition. Angioid streaks are often associated with pseudoxanthoma elasticum, but have been found to occur in conjunction with other disorders, including Paget's disease, sickle cell disease and Ehlers-Danlos Syndrome. Angioid means “like blood vessels”, and the condition is so named because Angioid streaks (AS) are crack-like dehiscence in Bruch’s membrane of the choroid and on funduscopy appear as greyish/red lines radiating from the optic disc. it is a disease of the connective tissure.

Acquired pseudoxanthoma elasticum These skin abnormalities frequently appear on the neck, armpits, and other areas that bend a great deal (referred to as flexure areas). Both decrease in CMT and partial or complete regression of fluorescein leakage were achieved. As the disease progresses, fragile new vessels may grow through the angioid streaks and hemorrhage, resulting in central vision loss. PXE affects several organs: the eyes, the skin, the cardiovascular system to name but a few and it manifests itself at the eye level by the appearance of choroidal-pigmented epithelium lesions called angioid streaks.
