Fibrinolysis and traumatic hyphaema.

Since January 1st 1975, 310 patients with traumatic hyphaema have been treated with the antifibrinolytic drug tranexamic acid. One secondary haemorrhage has occurred, corresponding to a frequency of secondary haemorrhage of 0.32%. Eighty-five of these patients were treated as out-patients. In four patients with traumatic hyphaema, who were not treated with tranexamic acid, the serum content of activator inhibitor was determined daily. An increase was seen during the first five days after the trauma, followed by a marked fall on the 6th day. In the same four patients, the central corneal thickness was followed by daily measurements and compared to the variation in activator inhibitor.
