Abstract

We had precise and accurate information concerning the position of the foreign body, its nature, and the extent of damage to the eye. A linear half-thickness incision which was paralleI to the limbus was made on the sclera immediately external to the location of the foreign body. A lamellar scleral undermining was performed on the both sides of a single scleral incision. Diathermy was applied in the area undermined. A T-shaped incision went all the way through the lamellar scleral bed, cleanly eXIo3ing the dark uveal tissue. The hand magnet was brought on the exposed choroid; the bulging of the choroid was obvious proof of its presence. And then gentle to-and-fro scratching with a nonmagnetic spatula on the bulging uveal tissue caused the foreign body to be extracted easily. The T-shaped incised scleral bed was closed. The preserved human sclera was burried in the lamellar dissected sclera. Practically any portion of the sclera up to a few millimeters in front of the optic nerve head can be approached. There were significant advantages to these procedures such as a high successful rate, a sufficiently promising effect in prophylaxis and treatment of the retinal detachment. Among 15 cases of the magnetic lOPB. including 7 cases of combined retinal detachments. 14 cases of IOFB and all cases of the retinal detachment showed to be completely recovered. The procedure failed in 1 case, in which foreign body located and adhered firmly on disc.
