[Fluorescein angiographic findings in retinal venous thromboses (author's transl)]

In addition to documenting pathologic vessel changes fluorescein angiography also makes it possible to show hemodynamic changes in retinal thrombosis. An interruption of laminary flow can be seen in the fluorescein angiogram at arteriovenous intersections. The retinal circulation time can be an aid to prognosis. If the interval does not exceed four seconds the prognosis is generally favorable but when it is considerably longer the prognosis with regard to visual acuity is generally poor and, furthermore, sequelae such as rubeosis iridis and secondary glaucoma must be expected. The therapeutic efficacy of laser coagulation can be judged more accurately by photographic and fluorescein angiographic documentation of the course.
