angioid streaks : ウィキペディア英語版 | angioid streaks Angioid streaks, also called Knapp streaks or Knapp striae are small breaks in Bruch's membrane, an elastic tissue containing membrane of the retina that may become calcified and crack.〔(DermAtlas ) - Johns Hopkins〕 ==History== They were first described by Robert Walter Doyne in 1889 in a patient with retinal hemorrhages. A few years later, ophthalmologist Hermann Jakob Knapp called them "angioid streaks" because of their resemblance to blood vessels. From histopathological research in the 1930s, they were discovered to be caused by changes at the level of Bruch's membrane. Presently, it is believed that its pathology may be a combination of elastic degeneration of Bruch's membrane, iron deposition in elastic fibers from hemolysis with secondary mineralization, and impaired nutrition due to stasis and small vessel occlusion.
