angioid streaks 

Degeneration of Bruch's membrane of the choroid characterized by brown or reddish lines or streaks in the fundus of the eye. The condition is bilateral, although one eye may be affected more than the other. Patients may occasionally be aware of some visual impairment in the visual field depending on the location of the streaks. The membrane is very fragile and liable to rupture in the case of ocular trauma, which may lead to macular haemorrhage and visual loss. Angioid streaks are often found in association with pseudoxanthoma elasticum (an eruption of small, superficial, solid elevation of the skin of the neck and other areas), Paget's disease, Ehlers-Danlos syndrome or sickle-cell anaemia. See choroidal neovascularization.

The resulting angioid streaks, characterized by irregular red-brown and gray lines extending peripherally from the peripapillary area, are the most common funduscopic finding of PXE.

PXE should be considered for patients with the fundoscopic finding of angioid streaks. The presence of skin lesions supports this diagnosis.
