The radiation therapy of Chronic Superficial Keratitis with Strontium 90

In this study 17 German Sheperds and mixed with Chronic Superficial Keratit is were evaluated after radiation therapy with Strontium 90. A 15 Gy dosage was delivered two times under general anaesthesia. In 13 dogs the non irridated eye served as negativ control and was treated only locally with 0,5 % Prednisoloneacetat (Ultracortenol(R)) before and 0, 2 % Ciclosporin (Optimmune(R)) after radiation. All 13 dogs improved within six months after irridation compared with the non radiated eye. In four dogs with bilateral loss of vision a superficial keratectomy was pe rformed before radiation therapy. The four dogs with a combined therapy reg ained vision after treatment. None of the dogs showed severe negative side effects in connection with the radiation therapy.
