Anatomy of Vitreous


The vitreous, also known as the vitreous humor, is a clear gel-like substance that fills the space between the lens and the retina in the human eye. The vitreous is composed mainly of water, but also contains collagen, hyaluronic acid, and various other proteins and enzymes.

Structure

The vitreous is a transparent, jelly-like substance that fills the space between the lens and the retina in the eye. It is composed of 99% water and 1% solid components, including collagen fibers, hyaluronic acid, and various proteins and enzymes. The vitreous has a gel-like consistency and is mostly made up of a network of collagen fibers.

The vitreous is attached to the retina by a thin layer of cells called the vitreous base. This attachment helps to keep the retina in place and provides a barrier to the movement of the vitreous.

Function

The vitreous plays several important roles in the eye. One of its main functions is to maintain the shape of the eye and provide mechanical support to the retina. The vitreous also helps to transmit light to the retina, and it can filter out some of the light that enters the eye, helping to reduce glare and improve visual acuity.

Another important function of the vitreous is to help protect the retina from injury. The vitreous is a relatively incompressible substance, which helps to absorb and distribute forces that might otherwise cause damage to the retina. This can be especially important in cases of injury or disease, when the vitreous can help to prevent further damage to the retina.

Problems with the Vitreous

There are several problems that can affect the vitreous and its functions. One common problem is called vitreous detachment, which occurs when the vitreous separates from the retina. This can cause floaters, which are small spots or strings that appear in the field of vision, and flashes of light. Vitreous detachment is a normal part of aging and is not typically harmful, but it can be a sign of a more serious problem, such as a retinal detachment, which requires immediate medical attention.

Another problem that can affect the vitreous is called vitreous hemorrhage, which occurs when blood enters the vitreous. This can cause floaters, as well as a loss of vision. Vitreous hemorrhage can be caused by a variety of conditions, including diabetes, high blood pressure, and eye injuries.

Conclusion

The vitreous is a clear gel-like substance that fills the space between the lens and the retina in the human eye. It is composed mainly of water, but also contains collagen, hyaluronic acid, and various other proteins and enzymes. The vitreous plays several important roles in the eye, including maintaining the shape of the eye, providing mechanical support to the retina, transmitting light to the retina, and protecting the retina from injury. However, problems such as vitreous detachment and vitreous hemorrhage can occur and require medical attention.

ABETALIPOPROTEINEMIA (BASSEN-KORNZWEIG SYNDROME) Retinopathy

Image
Abetalipoproteinemia, also known as Bassen-Kornzweig syndrome, is a rare genetic disorder that affects the body's ability to absorb and transport fats and fat-soluble vitamins. One of the ways that abetalipoproteinemia can affect the eyes is by causing retinitis pigmentosa, a condition that causes vision loss. Retinitis pigmentosa is a degenerative eye disease that affects the retina (the light-sensitive layer at the back of the eye). It is characterized by the gradual loss of photoreceptor cells (cells that detect light and send signals to the brain) and the accumulation of pigment in the retina. This can cause vision loss and may lead to blindness in severe cases. Abetalipoproteinemia can also cause optic atrophy, a condition in which the optic nerve (the nerve that carries visual information from the eye to the brain) becomes thin and weak. This can cause vision loss and other visual problems. In conclusion, abetalipoproteinemia can affect the eyes by causing reti...

What is myopia?

Image
Myopia is nearsightedness and this condition of eye occurs when the power of eye is increased from the normal powers of eye. The normal powers of eye is 58DS and the eye with >58DS eye power will be marked as myopic eye.  Definition   When parallel light rays coming from the infinity focus Infront of the retina while the accommodation should be at rest this condition of eye is known as myopia.

Scleritis

Scleritis 👌is a painful inflammation (swelling) the sclera. The tough, fibrous tissues of the sclera form a protective outer layer for the eye and make up 83 percent of the eye’s surface. In almost half of all cases, scleritis is associated with an underlying autoimmune disorder such as rheumatoid arthritis. There are two main types of scleritis: anterior and posterior. Anterior scleritis, the most common type, affects the front portion of the sclera. There are three types of anterior scleritis: Diffuse scleritis is the most common type and fortunately the most treatable. This type displays widespread redness and inflammation throughout the whole or a portion of the front portion of the sclera.     Nodular scleritis, is characterized by the presence of nodules , often tender to the touch, on the surface of the eye.     Necrotizing scleritis is the most severe form of anterior scleritis. It has the ability to destroy scleral tissues an...
