Ophthalmic applicator for treatment of pterygium or glaucoma using 32-P in combination with 103-Pd

摘要

Disclosed is an ophthalmic applicator for the treatment of pterygium or or glaucoma using a radioisotope. It comprises a source volume for containing the radioisotope therein; a filter volume for controlling a radiation dose emitted from the radioisotope; and an encapsulation volume for encompassing the source volume and the filter volume, wherein the radioisotope is pure 32 P or a combination of 32 P and 103 Pd. Ensuring the formation of more ideal dose distributions than do the conventional 90 Sr ophthalmic applicators, as described hitherto, the ophthalmic applicator for the treatment of pterygium or glaucoma using 32 P or a combination of 32 P and 103 Pd can promise both high therapeutic effects on pterygium or glaucoma and high safety effects on the eye lens. Further, 32 P and 103 Pd are easier to produce and treat than is 90 Sr, thereby allowing the radiotherapy to be useful.
