Asteroid hyalosis

The asteroids Hyalose is a degenerative appearance of the eye, in which form small milky-white opacities in the vitreous body of the eye. It is described in humans, dogs, and chinchillas. Clinically, the opacities are highly refractile, giving them appear in the night sky like stars and meteorites, these ghosting join the eye movements and therefore appear very mobile.

Such "stars" are floaters by the widespread Mouches to distinguish where it is fibrillar or cellular coagulates, that form in the vitreous. Exact causes for the emergence of an asteroid Hyalose are not known, but it seems correlations with the occurrence of diabetes mellitus, hypertension, hypercholesterolemia, and to give in some animals, tumors of the ciliary body. In dogs in attitude asteroide Hyalose seems to be a typical symptom of old age.

The deposits consist of hydroxyapatite, which is in turn formed from calcium and phosphates or phosphated lipids. Although the asteroid Hyalose usually causes no serious impairments of vision, but the haze can be very disturbing. They also affect studies and surveys of the retina. Normally, the asteroid Hyalose is not in need of treatment, but the vitrectomy may be indicated in some cases of diagnostic and therapeutic reasons.
