A study of the long-term results of treatment of 66 children with eye socket tumors has shown that use of a dose over 50 Gy in the postoperative period causes the development of radiation injuries of the facial skeleton and healthy eye. To lessen radiation exposure of the healthy organs and tissues it is advised that intracavitary radiotherapy should be used after eye socket exenteration. The use of this method makes it possible to deliver a necessary dose of irradiation to a focus of lesion with a 2-fold decrease in radiation exposure of the surrounding tissue.
