INFLAMATION OF THE UVEAL TRACT

 Inflammation of the uveal tract, also known as uveitis, is a serious condition that can lead to vision loss if left untreated. The uveal tract, which consists of the iris, ciliary body, and choroid, plays a crucial role in providing blood and oxygen to the retina, and maintaining the shape of the eye. In this article, we will discuss the causes, symptoms, diagnosis, and treatment of uveitis.

Causes of Uveitis

Uveitis can be caused by a variety of factors, including:

  1. Infections: Uveitis can be caused by bacterial, viral, or fungal infections. The most common infectious agents that cause uveitis include herpes simplex virus, syphilis, toxoplasmosis, and tuberculosis.
  2. Autoimmune disorders: Uveitis can be a complication of systemic autoimmune disorders such as rheumatoid arthritis, sarcoidosis, and ankylosing spondylitis.
  3. Trauma: Uveitis can be caused by physical trauma to the eye such as a blunt injury or a penetrating injury.
  4. Toxins: Uveitis can be caused by exposure to toxins such as pesticides and heavy metals.
  5. Idiopathic: In some cases, the cause of uveitis is unknown (idiopathic).

Symptoms of Uveitis

The symptoms of uveitis can vary depending on the location and severity of the inflammation. Some of the common symptoms include:

  1. Pain: Pain in or around the eye is a common symptom of uveitis.
  2. Redness: Uveitis can cause redness of the eye due to the inflammation of the blood vessels in the uveal tract.
  3. Light sensitivity: Uveitis can cause increased sensitivity to light.
  4. Blurred vision: Uveitis can cause blurred vision due to the inflammation of the retina.
  5. Floaters: Uveitis can cause floaters due to the inflammation of the vitreous humor.

Diagnosis of Uveitis

Uveitis is diagnosed through a thorough examination of the eye, including an examination of the retina, the iris, and the vitreous humor. The examination may include a visual acuity test, a visual field test, a dilated fundus exam, and a fluorescein angiography. In some cases, blood tests and imaging studies may be needed to identify the underlying cause of the uveitis.

Treatment of Uveitis

The treatment of uveitis depends on the underlying cause and the location and severity of the inflammation. Some of the common treatments include:

  1. Corticosteroids: Corticosteroids are used to reduce inflammation and pain. They may be administered topically, orally, or intravenously.
  2. Nonsteroidal anti-inflammatory drugs (NSAIDs): NSAIDs are used to reduce inflammation and pain. They may be administered topically or orally.
  3. Immunosuppressive drugs: In cases of uveitis caused by autoimmune disorders, immunosuppressive drugs such as methotrexate and azathioprine may be used to suppress the immune system.
  4. Antiviral and antibacterial drugs: In cases of uveitis caused by viral or bacterial infections, antiviral and antibacterial drugs may be used to treat the underlying infection.
  5. Surgery: In some cases, surgery may be needed to remove a foreign body, repair a wound, or remove a tumor.

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...

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...
