Corneal Stem Cell Transplant: Understanding and Managing a Revolutionary Treatment for Corneal Damage

Introduction 

Corneal stem cell transplant, also known as limbal stem cell transplant, is a revolutionary treatment for corneal damage that has the potential to restore vision and improve the appearance of the eye. This procedure is typically performed to replace damaged or diseased stem cells in the cornea with healthy ones, allowing the eye to regenerate and heal. In this article, we will discuss the causes, symptoms, and management of corneal stem cell transplant.

Causes 

Corneal stem cell transplant may be recommended in cases of:

  • Corneal stem cell deficiency: Stem cell deficiency can be caused by a variety of conditions, including chemical burns, Stevens-Johnson syndrome, and limbal stem cell deficiency, and can lead to corneal opacification and blindness.
  • Corneal injury: Injury to the cornea can damage or destroy the stem cells in the limbus, leading to corneal opacification and blindness.
  • Corneal disease: Certain diseases, such as ocular surface squamous neoplasia, can cause damage to the limbal stem cells, leading to corneal opacification and blindness.

Symptoms 

Symptoms of corneal stem cell deficiency can include:

  • Blurred vision
  • Distorted vision
  • Sensitivity to light
  • Glare and halos around lights
  • Redness or irritation of the eye
  • The feeling of a "gritty" sensation in the eye
  • Episodes of severe eye pain
  • Cloudy or opaque vision
  • Decreased visual acuity
  • A white ring around the iris
  • Sticky or gritty eyes

Diagnosis 

Corneal stem cell transplant is typically recommended based on a thorough eye examination, diagnostic tests such as a corneal topography, pachymetry, and a slit-lamp examination. Your doctor may also do a visual acuity test to measure your visual acuity and a Schirmer's test to measure the amount of tears produced.

Procedure 

Corneal stem cell transplant is typically performed as an outpatient procedure, meaning that the patient does not have to stay overnight in the hospital. The procedure is usually done under general anesthesia and takes about 2-4 hours.

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...
