Which description matches asteroid hyalosis in the vitreous?

• A. Small white particles of calcium or phospholipids
• B. Vitreal cells associated with uveitis
• C. Vitreal hemorrhage due to trauma or uveitis
• D. Vitreal degeneration 'floaters'

Answer: (A)

Asteroid hyalosis is defined by small, chalky white particles suspended in the vitreous. These opacities are calcium-phospholipid complexes, making them distinct from other vitreous findings. They appear as tiny white, refractile specks and are not inflammatory cells, and not blood from a hemorrhage. This description—small white particles of calcium or phospholipids—best captures what asteroid hyalosis looks like under the ophthalmoscope. Other options describe inflammatory cells, vitreous hemorrhage, or generic degenerative floaters, which don’t match the calcium-lipid composition and chalky white appearance of asteroid hyalosis.
