ULTRASONIC EXAMINATIONS OF FOREIGN BODIES IN THE POSTERIOR WALL OF THE EYE

Abstract

Eyes to be enucleated due to intraocular tumor or absolute glaucoma were used in an ultrasonic investigation of foreign bodies situated retrosclerally, or in the choroid‐scleral complex. The echograph findings of four intra‐choroidal, five intrascleral and three retroscleral foreign bodies were demonstrated. The foreign bodies were of iron, and were polygonal in shape. The intrachoroidal foreign bodies weighed 0.081–0.327 mg, the intrascleral 0.120–0.685 mg and the retroscleral 0.787–1.456 mg. In cases where double perforation is suspected, and where the ocular media are turbid, ultrasonography would appear capable of giving valuable information as to whether a foreign body is located intra‐ or extraocularly.
