CONGENITAL ANOMALIES OF UVEAL TRACT?

 The uveal tract, which consists of the iris, ciliary body, and choroid, is responsible for providing blood and oxygen to the retina, and maintaining the shape of the eye. Congenital anomalies of the uveal tract refer to the abnormal development of the uveal tract during prenatal development. These anomalies can lead to vision loss or blindness if left untreated. In this article, we will discuss some of the common congenital anomalies of the uveal tract, their causes, symptoms, and treatments.

Introduction

The uveal tract is a complex structure that develops during prenatal development. Congenital anomalies of the uveal tract can occur due to various genetic and environmental factors. These anomalies can range from minor structural defects to severe malformations that can lead to vision loss or blindness. Early diagnosis and treatment of congenital anomalies of the uveal tract can prevent further vision loss.

Aniridia

Aniridia is a congenital anomaly characterized by the absence or underdevelopment of the iris, the colored part of the eye that controls the amount of light entering the eye. It is caused by a genetic mutation on chromosome 11. The symptoms of Aniridia include:

  1. Vision loss: This can be severe or complete vision loss in one or both eyes.
  2. Nystagmus: This is an involuntary movement of the eyes.
  3. Photophobia: This is an abnormal sensitivity to light.
  4. Glaucoma: This is an increase in the pressure inside the eye, which can lead to vision loss.

Aniridia is treated with eye drops, laser therapy, or surgery to control the pressure inside the eye and prevent further vision loss.

Coloboma

Coloboma is a congenital anomaly characterized by a gap or cleft in the iris, ciliary body, or choroid. It is caused by a failure of the embryonic fissure to close during prenatal development. The symptoms of Coloboma include:

  1. Vision loss: This can be severe or complete vision loss in one or both eyes.
  2. Nystagmus: This is an involuntary movement of the eyes.
  3. Photophobia: This is an abnormal sensitivity to light.
  4. Cataract: This is a clouding of the lens inside the eye, which can lead to vision loss.

Coloboma is treated with eye drops, laser therapy, or surgery to remove the cataract and prevent further vision loss.

Iris Coloboma

Iris coloboma is a congenital anomaly characterized by a gap or cleft in the iris. It is caused by a failure of the embryonic fissure to close during prenatal development. The symptoms of Iris coloboma include:

  1. Vision loss: This can be severe or complete vision loss in one or both eyes, although it is rare.
  2. Nystagmus: This is an involuntary movement of the eyes.
  3. Photophobia: This is an abnormal sensitivity to light.
  4. Glaucoma: This is an increase in the pressure inside the eye, which can lead to vision loss.

Iris coloboma is treated with eye drops, laser therapy, or surgery to control the pressure inside the eye and prevent further vision loss.

Choroidal Hemangioma

Choroidal Hemangioma is a congenital anomaly of the choroid characterized by the formation of benign tumors of blood vessels.

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...
