Macular Dystrophy: Understanding and Managing a Progressive Eye Condition

 Introduction 

Macular dystrophy is a rare, inherited corneal disorder characterized by the formation of small, raised, and/or pigmented lesions on the cornea known as "macular" lesions. These lesions can cause a variety of visual symptoms and can lead to serious vision problems if left untreated. In this article, we will discuss the causes, symptoms, and management of macular dystrophy.

Causes 

Macular dystrophy is caused by mutations in the TGFBI gene. This gene provides instructions for making a protein called keratoepithelin, which is essential for the normal development and maintenance of the cornea. When the TGFBI gene is mutated, the keratoepithelin protein is abnormal and can form macular lesions on the cornea. There are several subtypes of macular dystrophy, each caused by different mutations in the TGFBI gene.

Symptoms 

Symptoms of macular dystrophy can include:

  • The appearance of small, raised, and/or pigmented macular lesions on the cornea
  • Cloudy or hazy vision
  • Blurred vision
  • Sensitivity to light
  • The feeling of a foreign body in the eye
  • Redness or irritation of the eye
  • The feeling of a "gritty" sensation in the eye
  • Episodes of severe eye pain
  • Progressive vision loss

Diagnosis 

Macular dystrophy is typically diagnosed based on the appearance of the characteristic macular lesions on the cornea and a physical examination of the eye. Your doctor may use a microscope to examine the cornea and may also use a variety of other diagnostic tools

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...
