Usually caused by trauma, causingan Iridodialysis. Blood fills the anterior chamber completely. Due to lack of oxygen the initially red blood turns very dark. Often combined with high intra-ocular pressure (see injection of the conjunctiva). The coagulum has to be removed within 5 days to avoid scar formationin the chamber angle.
