The hyaloid membrane is a thin, transparent layer that covers the front part of the vitreous body of the eye. There are several synonyms for this term, including vitreous membrane, hyaloid sheath, and membrana limitans hyaloidea. In addition, some sources refer to this structure as the hyaloid canal or hyaloid fossa when discussing its role in the formation of the eye during embryonic development. Regardless of the terminology used, the hyaloid membrane plays an important role in maintaining the structure and function of the eye. It helps to transmit light to the retina, protects the delicate structures inside the eye, and supports healthy visual function.
