Mobile vitreous cysts.

Cysts of uveal origin in the vitreous.

CYSTS in the vitreous, originating from the uvea, are very rare; they may be divided into congenital, traumatic, neoplastic, degenerative, and inflammatory.

Parathyroid cysts and cervical thymic cysts are known to be a rare entity. Reviewing the world literature of the latter two, only a few reports were noted. There is, in addition, some confusion in terminology...

A Novel Artificial Vitreous Substitute – Foldable Capsular Vitreous Body

It has a thin, membrane-like structure corresponding to the vitreous cortex that extends from the ora serrata to the posterior pole.1 It is somewhat spherical but slightly flattened meridionally, and it has a cup-shaped depression in its anterior side. It consists of about 99% water by we...
