I. Introduction In a previous paper1 we reported the successful treatment of 2 eyes with traumatic total hyphema and secondary glaucoma by irrigation with fibrinolysin. The present paper reports data on 8 eyes treated by us and on 56 eyes submitted to us by other ophthalmologists. Fibrinolysin (Thrombolysin)* is a proteolytic enzyme prepared commercially by exposing high concentrations of purified profibrinolysin from human plasma to an activator substance, purified streptokinase. Fibrinolysin has a lytic effect on the fibrin clot, which is dissolved and can be irrigated from the anterior chamber. We also are reporting experimental work with fibrinolysin used in rabbit eyes.
