Fixed, moving or shooting stars? A study of asteroid hyalosis

Asteriod hyalosis is a degenerative condition where calcium soaps accumulate in the vitreous. These bodies are reported to move in wavelike undulations however the majority of patients do not notice these bodies and they do not affect visual acuity. Asteriod hyalosis is visible though on fundal photographs and obscures the view of the retina leaving the patient with ungradable images requiring a hospital eye appointment to assess the retina.

This audit looks at the density, movement and shape of these bodies to discover if asteroid hyalosis continue to develop, if it regresses, how it moves and if all these patients need to be continually screened under the eye clinic.
