112 patients with traumatic hyphaema were investigated prospectively over a period of 3 years. 53 had conservative treatment and 59 tranexamic acid treatment. They were hospitalized, but fully mobilized. Both groups were given supplementary local therapy with glucocorticoids and mydriatics as well as monocular patching. In neither group was any re-bleeding seen. The resorption of blood was delayed in the tranexamic treated patients, which may be taken as indirect proof of the efficacy of the treatment. The longer persistence of blood in the anterior chamber in the tranexamic acid treated group caused no complication. The treatment was well tolerated. In both departments treatment with tranexamic acid had replaced the bed rest treatment.
