Asteroid hyalose
It is the presence of tiny white solid corpuscles dispersed in an otherwise normal vitreous. It is a dystrophic change that does not require treatment or makes significant interference.
Scintilating synhesia (holesterolosis of the eyeball)
It is seen as bright holster crystals that float freely in the vitreous. Their appearance is due to severe intraocular disease, usually bleedings in the vitreous. It shouldn’t be confused with the asteroid hyalose.
Inflammatory changes in the vitreous
Isolated inflammation of the vitreous (vitritis), or only of hyalose membrane (hyalovitritis) are rare. Typically, the inflammatory elements in the vitreous are a result of the inflammation of the uvea and / or retina (chorioretinitis, cyclitis, endophthalmitis, sympathetic ophtalmia).
Injuries of the vitreous
With perforate injuries and after surgery on the eye prolapse and vitreous loss are possible. It is treated by closing the perforation and by the replacement of the lost volume with buffered saline. By losing one part, the architectonics of the remaining vitreous is disrupted, which eventually can cause retinal ablation. Therefore, if greater loss of the vitreous occurs, the remaining part of the vitreous must be removed by vitrectomy. With traumatic vitreous hemorrhage as a result of injury in the retina or any other part of the uvea, treatment is primarily focused on those injuries. If the spontaneous resumption of bleeding does not occur within 2-3 months, and bleeding significantly reduces sight, vitrectomy is made. Foreign bodies in the vitreous are usually surgically removed because, even when they are not dangerous to other ocular structures, they bring the risk of infection.
