Asteroid hyalosis may also be referred
to by its former name, asteroid hyalitis.
Asteroid hyalosis is a degenerative condition (i.e.
involving the deterioration and loss of specialized function of the cells
of a tissue or organ) in which very small deposits of calcium are suspended
in the vitreous
humour of the eye.
This age-related condition is known to affect dogs as well as humans.
Asteroid hyalosis does not usually severely affect vision
but the floating particles can be irritating to those affected. Treatment
is not usually necessary but
vitrectomy (removal of part or all of the vitreous humour) may be
suggested in some cases - for both diagnostic or therapeutic reasons.
