The subsequent study has evaluated ocular blood flow during several stages of experimentally induced immunogenic uveitis in rabbits. Blood flow was measured following intracardiac injection of carbonized microspheres (25μ±5μ) labeled with strontium chloride Sr 85. In acute or chronic mild inflammation, ocular blood flow is elevated. In severe acute Inflammation, ocular blood flow is markedly diminished. This decrease correlates with the presence of an extensive uveal vasculitis and thromboses primarily in choroidal blood vessels and helps explain on a pathogenetic basis some of the phenomena encountered in uveitis.
