MEMBRANA HYALOIDEA Meaning and
Definition
-
The term "membrana hyaloidea" refers to a thin and transparent layer of tissue within the eye, specifically the embryonic structure that develops during fetal development. More commonly known as the hyaloid membrane or the vitreous membrane, it is a delicate structure that plays a crucial role in the development and functioning of the eye.
The membrana hyaloidea lies within the vitreous humor, a gel-like substance that fills the posterior chamber of the eye between the lens and the retina. It provides both structural support and maintains the shape of the eye. Essentially, it acts as a scaffold for various components of the eye during its developmental stages.
During embryonic development, the membrana hyaloidea is primarily responsible for nourishing the developing lens and retina. As the eye continues to mature, the hyaloid artery that supplies the lens and retina regresses, leaving behind a residual fibrous remnant known as the hyaloid canal. This canal eventually forms the hyaloid artery and the hyaloid vessels, which are important for nourishing the avascular structures of the eye.
In certain instances, the membrana hyaloidea may fail to regress properly during embryogenesis, resulting in a condition called persistent hyperplastic primary vitreous (PHPV). This condition can lead to visual impairments and may require surgical intervention.
In summary, the membrana hyaloidea is a vital embryonic tissue in the eye that ensures appropriate nourishment and development of structures such as the lens and retina.

Etymology of MEMBRANA HYALOIDEA
The word "membrana hyaloidea" is derived from Latin and Greek roots.
The term "membrana" comes from the Latin word "membrāna", which means "thin skin" or "membrane".
The word "hyaloidea" is a combination of the Greek words "hyalos" meaning "glass" and "eidos" meaning "appearance" or "likeness". In this context, "hyaloidea" refers to the vitreous humor of the eye, which has a glassy or transparent appearance.
Therefore, "membrana hyaloidea" can be translated as the "membrane of glassy appearance" or "membrane resembling glass", referring to the thin membrane that separates the vitreous humor from the retina in the eye.
