Cysts and Tumors of Conjunctiva

 The conjunctiva is a thin, transparent membrane that lines the inner surface of the eyelids and covers the white part of the eye (called the sclera). It plays an important role in maintaining the health of the eye by producing mucus and tears, which help to keep the surface of the eye moist and lubricated. Cysts and tumors of the conjunctiva are a group of eye conditions that are characterized by the presence of abnormal growths on the conjunctiva. These conditions can range from benign to malignant, and they can affect one or both eyes.

One example of a cyst of the conjunctiva is a chalazion, which is a small, benign cyst that appears on the eyelid. Chalazia are most commonly caused by a blockage of one of the meibomian glands, which are small glands located in the eyelids that produce the oily layer of the tear film. Chalazia usually do not cause any symptoms, but they may be noticed as a small bump on the eyelid. In some cases, chalazia may cause symptoms such as redness, swelling, and a feeling of foreign body sensation or scratchiness in the eye. Treatment of chalazia may involve the use of warm compresses and lid hygiene measures to help resolve the blockage and prevent the cyst from recurring. In severe cases, surgery may be necessary to remove the cyst.

Another example of a cyst of the conjunctiva is a conjunctival inclusion cyst, which is a small, benign cyst that appears on the conjunctiva. Conjunctival inclusion cysts are usually caused by a blockage of the glandular structures of the conjunctiva, and they are most commonly seen in newborns. Conjunctival inclusion cysts usually do not cause any symptoms, but they may be noticed as a small bump on the conjunctiva. In some cases, conjunctival inclusion cysts may cause symptoms such as redness, swelling, and a feeling of foreign body sensation or scratchiness in the eye. Treatment of conjunctival inclusion cysts may involve the use of warm compresses and lid hygiene measures to help resolve the blockage and prevent the cyst from recurring. In severe cases, surgery may be necessary to remove the cyst.

Tumors of the conjunctiva are abnormal growths that can occur on the conjunctiva, and they can range from benign to malignant. Benign tumors of the conjunctiva include papillomas, which are small, wart-like growths, and pterygia, which are triangular-shaped fleshy bumps on the conjunctiva. Malignant tumors of the conjunctiva include squamous cell carcinomas, which are the most common

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...
