BIODEGRADABLE SCLERA PLUG.

摘要

This invention relates to a sclera plug consisting of a lactocopolymer, a sclera plug containing a drug and designed so as to release the drug gradually into a vitreous body, and a sclera plug used to cure or prevent a retinal disease by utilizing the sustained release action of the drug and promote the healing of a vitreous body after a surgical operation thereon. The sclera plug according to the present invention closes effectively an opening made during a surgical operation on a vitreous body, and need not be removed after the surgical operation. When this sclera plug is used, a drug can be released gradually for a long period of time into intraocular tissues into which the permeating of a drug is otherwise very difficult, so that the administration of a drug can be carried out safely and effectively. Moreover, a simple clinically applicable administration method can be found by utilizing a sclera cut made during a surgical operation on a vitreous body.
