Fig. 8. Asteroid hyalosis. A. Myriad tiny white spherules are suspended throughout the vitreous framework. B. Bodies appear composed of an outer dense ring and a central homogeneous zone. C. Central zone contains birefringent material as seen in polarized light. D. Asteroid body is composed of round particles of equal size in a symmetrical arrangement, growing more dense toward the center. The particles appear embedded in a matrix that merges with the surrounding vitreous and seems to be of the same substance.
