Abstract

The present invention provides a shield apparatus for protecting eyeball structures in radiation therapy for a tumor in an eye portion, particularly an eyelid(eyelid) or the conjunctiva. The shield apparatus is a goggle-type patient-customized eyeball shield apparatus for use in radiation therapy, including a pair of lens frames connected by a center connection part, temples, and nose pads. The goggle-type patient-customized eyeball shield apparatus for use in radiation therapy includes the lens frames configured such that open tops are formed by cutting away the upper portions thereof, respectively, and lens grooves are formed along the inner circumferences thereof, respectively; lenses inserted into the respective lens grooves through the open tops; and shields each fastened onto the surface of each of the lenses via any one of a plurality of fastening holes passing through the lens, and configured to shield radiation to be applied to eyeballs. An advantage arises in that the vertical relationship between a radiation beam and a treated portion can be changed or maintained because the bending angles of the lens frames and temples of the shield apparatus and the locations of the shields can be immediately controlled in accordance with the shape of the face of a patient and the locations of the eyes and pupils of the patient.
