One patient with persistent hypotony after cyclodialysis and another one after contusion of the eyeball with recessed angle and traumatic cyclodialysis were successfully treated as follows: Blood plasma of the patient is injected in the anterior chamber and fibrinogen is transformed into fibrin by recalcification. Both patients attained normal intraocular pressure after this treatment and the signes of persistent hypotony disappeared. This seems to be an essential advantage compared with surgical interventions. Our method is very easy in practice and allows repeated treatment. A possible transformation of fibrinogen into fibrin in the vitreous cavity of an aphacic eye is resorbed very early without visible inflammatory signs. In contrast to the proposed surgical intervention in the literature, no pathological rise of the intraocular pressure for more than a few days was seen.
