lasiaisneste

Lasiaisneste, also known as the vitreous humor, is the clear, gel-like substance that fills the space between the lens and the retina in the back of the eye. It is primarily composed of water (about 98-99%), with small amounts of collagen, hyaluronic acid, and other molecules. This gel-like consistency helps maintain the shape of the eyeball and provides a medium for light to pass through unimpeded to reach the retina.

The vitreous humor plays a crucial role in maintaining intraocular pressure and supporting the structures of the eye. As we age, the vitreous humor undergoes a process called liquefaction, where the gel begins to break down and become more watery. This can lead to the formation of floaters, which are small specks or strands that appear to drift in the field of vision. While generally harmless, persistent or significantly increasing floaters, especially if accompanied by flashes of light or a curtain-like shadow, can be a sign of a more serious condition like a retinal tear or detachment and should be evaluated by an eye care professional.

The vitreous humor is avascular, meaning it does not contain blood vessels. It receives nutrients from the surrounding tissues, such as the retina and the lens. Unlike some other bodily fluids, the vitreous humor does not regenerate once it is significantly altered or removed. Surgical procedures may be necessary to remove or replace portions of the vitreous humor in cases of significant vitreous hemorrhage or retinal detachment.
