[Cryoimmunotherapy of herpetic and metaherpetic keratitis]. / Kryoimunoterapie herpetické a metaherpetické keratitidy.

In 11 patients with relapsing herpetic keratitis and metaherpetic ulcers cryoimmunotherapy, as recommended by Amoils, was applied. Under instillation anaesthesia three cryocycles were made using a temperature of -80 degrees on the entire area of the lesion with subsequent instillation of 60 drops (1 drop per minute) of serum obtained from 15 ml of the patient's blood mixed with 5 ml gamma globulin. In all 11 patients progression of the disease was arrested, though it could not be checked by previous conservative therapy. The cornea cleared and vision improved. The method is effective, simple and expands therapeutic procedures which can be used in these tiresome conditions.
