Aqueous Humour of Eye

 The aqueous humor is a clear, watery fluid that fills the anterior and posterior chambers of the eye. It is produced by the ciliary body, a ring of muscle located behind the iris that is responsible for maintaining the shape of the lens and producing aqueous humor. The aqueous humor flows out of the ciliary body and into the posterior chamber before entering the anterior chamber, a space located between the cornea and iris.

The aqueous humor serves several important functions in the eye. It helps to maintain the shape of the eye and provide nutrients to the front of the eye. It also helps to remove waste products from the front of the eye and regulate the pressure within the eye, which is important for proper eye function.

The aqueous humor is constantly being produced and replaced. It flows out of the eye through the trabecular meshwork, a network of tiny channels located at the angle where the cornea and sclera meet. The trabecular meshwork acts as a filter, allowing excess aqueous humor to drain out of the eye and be replaced with new fluid.

Problems with the aqueous humor can lead to a variety of eye problems. One common problem is glaucoma, a condition that occurs when the pressure within the eye becomes too high. This can be caused by a variety of factors, including an increase in the production of aqueous humor or a decrease in the drainage of aqueous humor from the eye.

High intraocular pressure can damage the optic nerve, leading to vision loss and blindness. Glaucoma is often treated with eye drops, laser therapy, or surgery to lower the pressure within the eye.

Other problems with the aqueous humor can include inflammation and infection, which can be caused by a variety of factors, including injury, allergies, or the use of contact lenses. These conditions can be treated with medications, such as antibiotics or anti-inflammatory drugs, or with surgery.

The aqueous humor can also be affected by trauma or injury to the eye. This can cause bleeding or swelling within the eye, leading to vision loss or other problems. In these cases, prompt medical treatment is essential to prevent further damage to the eye.

Overall, the aqueous humor is an important part of the eye's circulation system, and problems with this fluid can lead to a variety of eye problems. Regular eye exams and prompt treatment of any problems can help to maintain the health of the aqueous humor and protect vision.

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...
