Hyaloid artery

Hyaloid artery is an artery in the eye that plays a crucial role in the development of the eye's vascular system. It is a temporary structure that typically disappears after birth, but in some cases, remnants may persist.

Etymology[edit | edit source]

The term "hyaloid" comes from the Greek words "hyalos," meaning glass, and "eidos," meaning form or shape. This is in reference to the transparent nature of the hyaloid artery.

Anatomy[edit | edit source]

The hyaloid artery originates from the ophthalmic artery, which is a branch of the internal carotid artery. It enters the eye through the optic disc, and extends to the lens of the eye. The hyaloid artery forms a network of capillaries around the lens, known as the tunica vasculosa lentis.

Function[edit | edit source]

The primary function of the hyaloid artery is to supply blood to the developing lens and vitreous humor of the eye during fetal development. After birth, the hyaloid artery typically atrophies and disappears, as its function is taken over by other blood vessels in the eye.

Clinical significance[edit | edit source]

In some cases, remnants of the hyaloid artery may persist after birth, a condition known as Persistent Hyperplastic Primary Vitreous (PHPV). This can lead to various eye problems, including cataracts, glaucoma, and microphthalmia. Treatment typically involves surgery to remove the remnants of the hyaloid artery.
