Abstract

Tumors of the eye occur in every portion and are composed of all conceivable types of tissue. While the ultrasonographer of today works primarily with diagnostic tools of high prowess in the vitreous, posterior ocular wall, and orbit, the rapidly advancing technical achievements of sonographic equipment will soon permit scanning of lesions heretofore not easily imaged. Tumors of the lid, conjunctiva, cornea, lacrimal sac, and sinuses may now be partially investigated with A-mode using 10, 15, 20, and 25 MHz transducers. A-mode analysis may currently give useful information on the biologic nature of superficial tumors. The sonographer should be aware of the clinical and pathologic nature of all types of eye tumors so that he will be immediately able to apply the more sophisticated scanners of the future to lesions of the globe, orbit, and regional anatomic structures.
