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...

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...

Pinguecula

A pinguecula is a small, raised, yellowish growth on the conjunctiva (the clear, thin membrane that covers the white part of the eye). It is a benign (non-cancerous) condition that is common in people who spend a lot of time outdoors, especially in sunny or windy conditions. Pingueculae are made up of fats, proteins, and other substances and are usually harmless, but they can cause discomfort and irritation if they rub against the cornea (the clear, dome-shaped structure at the front of the eye) or the lens (the transparent structure behind the iris). They can also cause vision problems if they become large or obstruct the field of vision. Pingueculae can be diagnosed during a comprehensive eye exam, during which the eye care professional will examine the eye and may use specialized instruments to examine the conjunctiva and other parts of the eye. They are usually benign and do not require treatment, but if they are causing discomfort or interfering with vision, they can be r...
