Composition of Asteroid Bodies

WAYNE MARCH 1, DAVID SHOCH 1, and RICHARD O'GRADY 1

1 Department of Ophthalmology, North-western University, 303 E. Chicago Ave., Chicago, Ill. 60611

The human asteroid body by scanning electron microscopy is surrounded by a tightly adhering network of collagen fibrils. Smaller "satellite" asteroid bodies appear on and partially submerged in the surface of the larger body. Transmission electron microscopy reveals electron-opaque particles symmetrically arranged in these satellite asteroids. X-ray spectroscopy demonstrates the presence of calcium, sulfur, and phosphorus.

Key Words: asteroid • vitreous • vitreal opacity • electron probe • scanning electron microscope • ultrastructure • calcium • sulfate • collagen fibrils • mucopolysaccharide
