Keratoglobus: Understanding and Managing a Rare Eye Condition

Introduction 

Keratoglobus is a rare, congenital disorder characterized by a thinning and bulging of the cornea, resulting in a globus-shaped deformity. This deformity 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 keratoglobus.

Causes 

The exact cause of keratoglobus is not known, but it is thought to be a congenital disorder. It is believed to be caused by a genetic mutation that affects the structure and stability of the cornea. It is also thought to be caused by a deficiency of collagen fibers which are responsible for cornea's strength and stability.

Symptoms 

Symptoms of keratoglobus can include:

  • Blurred vision
  • Distorted vision
  • Sensitivity to light
  • Glare and halos around lights
  • Progressive myopia and astigmatism
  • Redness or irritation of the eye
  • The feeling of a "gritty" sensation in the eye
  • Episodes of severe eye pain
  • Progressive vision loss
  • Extremely thin cornea
  • Prominent cornea

Diagnosis 

Keratoglobus is typically diagnosed based on the characteristic symptoms and a thorough eye examination. Your doctor may use a variety of diagnostic tools such as corneal topography, pachymetry, and corneal tomography to confirm the diagnosis.

Treatment 

Treatment for keratoglobus will vary depending on the severity of the condition. In mild cases, treatment may involve the use of glasses or contact lenses to correct vision. In more severe cases, treatment may involve the use of corneal cross-linking, which uses UV light and riboflavin to strengthen the cornea and prevent further bulging. In some cases, surgery such as a corneal transplantation or intrastromal ring segments may be necessary to improve vision and manage symptoms.

Prevention 

As the exact cause of keratoglobus is not known, there is no surefire way to prevent it. However, early detection and treatment of the condition can help prevent vision loss and manage the symptoms. It is recommended that individuals with a family history of keratoglobus or at risk factors should have regular eye check-ups with an ophthalmologist, who may refer to a corneal specialist if necessary.

Conclusion 

Keratoglobus is a rare, congenital disorder characterized by a thinning and bulging of the cornea, resulting in a globus-shaped deformity. This deformity can cause a variety of visual symptoms and can lead to serious vision problems if left untreated. The exact cause of keratoglobus is not known, but it is thought to be a congenital disorder. With proper diagnosis and management, the progression of keratoglobus can be slowed, and vision loss can be prevented. It is important to consult an ophthalmologist if you suspect you may have keratoglobus, as early treatment can prevent the progression of the disease and preserve vision.

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...
