Abstract
Assuming that fibrinolytic activity may play a role in cases of recurrent bleeding in traumatic hyphema, a microassay method for determining fibrinolytic activity in the aqueous humor was developed. Results indicate that the rabbit aqueous contains relatively low levels of fibrinolysin and high levels of fibrinolysin activators. Systemic administration of acetylsalicylic acid in therapeutic doses is shown to reduce the fibrinolytic activity in the aqueous of the rabbit substantially.
