SPECIFIC TYPES OF UVEITIS

 Uveitis is a general term used to describe inflammation of the uveal tract, which includes the iris, ciliary body, and choroid. The uveal tract is responsible for producing aqueous humor and providing blood supply to the retina. Uveitis can be caused by a variety of underlying conditions and can lead to severe vision loss or blindness if left untreated.

Types of Uveitis:

  1. Anterior Uveitis:
  • Anterior uveitis, also known as iritis, is an inflammation of the iris and the anterior chamber of the eye.
  • It is the most common form of uveitis and is characterized by eye pain, redness, and light sensitivity.
  • It can be caused by a variety of underlying conditions, including infections, autoimmune disorders, and sarcoidosis.
  1. Intermediate Uveitis:
  • Intermediate uveitis, also known as pars planitis, is an inflammation of the pars plana, which is the area between the iris and the retina.
  • It is characterized by floaters, blurred vision, and visual field loss.
  • It can be caused by a variety of underlying conditions, including sarcoidosis, multiple sclerosis, and certain types of infections.
  1. Posterior Uveitis:
  • Posterior uveitis, also known as choroiditis, is an inflammation of the choroid and the retina.
  • It is characterized by floaters, blurred vision, and visual field loss.
  • It can be caused by a variety of underlying conditions, including infections, autoimmune disorders, and sarcoidosis.
  1. Panuveitis:
  • Panuveitis is a type of uveitis that affects all layers of the uveal tract, including the iris, ciliary body, and choroid.
  • It is characterized by severe eye pain, redness, and vision loss.
  • It can be caused by a variety of underlying conditions, including infections, autoimmune disorders, and sarcoidosis.

Risk Factors:

  • Some of the risk factors for uveitis include:
    • Having a history of autoimmune disorders such as rheumatoid arthritis, ankylosing spondylitis, or inflammatory bowel disease
    • Having a history of exposure to certain toxins or radiation
    • Being immunocompromised
    • Having a history of previous eye infections

Diagnosis:

  • The diagnosis of uveitis typically involves a thorough examination of the eye by an ophthalmologist.
  • This may include visual acuity testing, a slit-lamp examination, and imaging tests such as ultrasound or magnetic resonance imaging (MRI) to assess the size and structure of the eye.

Treatment:

  • Treatment for uveitis typically involves a combination of medications and therapies, depending on the underlying cause of the condition and the severity of the symptoms.
  • Medications such as corticosteroids, immunosuppressive drugs, and antibiotics may be used to reduce inflammation and prevent complications.
  • In severe cases, surgery may be needed to remove the affected tissue and prevent further damage.

Prevention:

  • To reduce the risk of uveitis, it is important to take steps to protect your eyes from infection and injury, such as:
    • Washing your hands frequently
    • Avoiding touching or rubbing your eyes
    • Wearing protective eyewear when participating in activities that may cause eye injury
    • Promptly treating any eye infections or injuries

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...
