SCLERITIS

 Scleritis is a serious eye condition characterized by inflammation of the sclera, the white part of the eye. Unlike episcleritis, which affects only the outermost layer of the sclera, scleritis involves inflammation of the deeper layers of the sclera. The condition can cause significant pain and visual disturbances and, if left untreated, can lead to serious vision loss. In this article, we will discuss the causes, symptoms, and treatment options for scleritis.

Causes of Scleritis

Scleritis can be caused by a variety of factors, including infections, autoimmune disorders, and certain medications. In some cases, the cause is unknown.

  • Infections: Some types of bacterial infections can cause scleritis. For example, the bacteria that cause streptococcal pharyngitis (strep throat) can cause scleritis in some people.
  • Autoimmune disorders: Scleritis is often associated with certain autoimmune disorders, such as rheumatoid arthritis, lupus, and scleroderma.
  • Medications: Some medications, such as non-steroidal anti-inflammatory drugs (NSAIDs) and beta-blockers, can cause scleritis as a side effect.

Symptoms of Scleritis

The most common symptom of scleritis is severe pain in the affected eye. Other symptoms can include:

  • Redness and inflammation of the affected eye
  • Sensitivity to light
  • Blurred vision
  • Tearing
  • A gritty or burning sensation in the eye

Scleritis can affect one or both eyes, and the symptoms can vary in severity. Some people may experience only mild discomfort, while others may have more severe symptoms.

Diagnosis and Treatment of Scleritis

Scleritis is typically diagnosed based on a physical examination and a review of the patient's medical history. An ophthalmologist (eye doctor) may use a special dye to highlight the affected area and help make the diagnosis. In some cases, additional tests, such as a blood test or an imaging study, may be needed to rule out other conditions.

The treatment of scleritis depends on the underlying cause, if known. In most cases, the condition is treated with a combination of medications, including anti-inflammatory drugs (such as corticosteroids) and immunosuppressive drugs. These medications can help reduce inflammation and pain, as well as prevent further damage to the eye.

In cases of scleritis caused by an infection, the underlying infection should be treated with antibiotics or other appropriate medications.

If the scleritis is caused by an autoimmune disorder, the underlying disorder should be treated. Medications such as methotrexate, azathioprine, or mycophenolate mofetil, are often used to treat autoimmune disorder-associated scleritis.

If the scleritis is caused by a medication, the medication should be stopped if possible. If the medication is necessary, a different medication may be prescribed.

In cases of recurrent or severe scleritis, referral to a rheumatologist or immunologist may be necessary for further evaluation and management.

Complications of Scleritis

Scleritis can cause serious vision loss if left untreated. The inflammation and scarring caused by the condition can damage the structures of the eye and lead to complications such as cataracts, glaucoma, and retinal detachment.

Prevention of Scleritis

There is no surefire way to prevent scleritis, as the cause is often unknown. However, early diagnosis and prompt treatment can

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...
