At the 1910 meeting of the Heidelberg Ophthalmological Congress Purtscher described a peculiar condition of the fundi, consisting of exudate and superficial hemorrhages in one eye and a large preretinal clot in the other. The condition followed a head injury. Purtscher called it "angiopathic retinae traumatica" and stated that it was caused by cerebrospinal fluid in the perivascular lymph spaces of the retina and in the choroidal space. Since that time several cases have been reported. In all probability Jacobi was the first to record the white peripapillary patches and the retinal hemorrhages seen after a fracture of the skull. His description of the fundus was brief. The appended bibliography covers the majority of the cases in which the condition can be likened to or mistaken for traumatic retinal angiopathy.
Extravasation of blood in the fundus following a head injury or compression of the thorax had been described long before
