DIFFERENCES BETWEEN GRANULOMATOUS AND EXUDATIVE ANTERIOR UVEITIS

 Anterior uveitis is a type of inflammation that affects the front part of the uveal tract, specifically the iris and ciliary body. It can be divided into two types: granulomatous and exudative anterior uveitis. The main difference between these two types is the presence or absence of granulomas, which are small clusters of inflammatory cells. In this article, we will discuss the differences between granulomatous and exudative anterior uveitis, including their causes, symptoms, and treatments.

Introduction

Anterior uveitis is a common condition that can occur at any age, but is more common in young adults. It is an inflammation of the iris and ciliary body, the front part of the uveal tract. Anterior uveitis can be classified into two types: granulomatous and exudative anterior uveitis. The main difference between these two types is the presence or absence of granulomas.

Granulomatous Anterior Uveitis

Granulomatous anterior uveitis is characterized by the presence of granulomas, which are small clusters of inflammatory cells. The most common cause of granulomatous anterior uveitis is sarcoidosis, an autoimmune disorder. Other causes include tuberculosis, syphilis, and fungal infections. The symptoms of granulomatous anterior uveitis include:

  1. Eye pain: This can be a dull or severe pain in the eye.
  2. Redness of the eye: This can occur due to the inflammation and increased blood flow to the eye.
  3. Photophobia: This is an abnormal sensitivity to light.
  4. Blurred vision: This can occur due to the inflammation and swelling of the iris and ciliary body.
  5. Floaters: This can occur due to the inflammation and swelling of the vitreous humor, the gel-like substance that fills the back of the eye.

The treatment of granulomatous anterior uveitis depends on the underlying cause of the condition. The most common treatments include:

  1. Topical corticosteroids: These are anti-inflammatory medications that are applied directly to the eye. They are used to reduce the inflammation and prevent further vision loss.
  2. Oral corticosteroids: These are anti-inflammatory medications that are taken by mouth. They are used to reduce the inflammation and prevent further vision loss.
  3. Immunomodulatory therapy: This type of therapy is used to suppress the immune system, which is overactive in autoimmune disorders.
  4. Antitubercular therapy: This type of therapy is used to treat tuberculosis.

Exudative Anterior Uveitis

Exudative anterior uveitis is characterized by the absence of granulomas. The most common cause of exudative anterior uveitis is acute anterior uveitis, a type of iritis. Other causes include herpes simplex virus, syphilis, and trauma. The symptoms of exudative anterior uveitis are similar to those of granulomatous anterior uveitis, including eye pain, redness of the eye, photophobia, blurred vision, and floaters.

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...
