Keratoglobus - Symptoms, Causes and Treatment


What is Keratoglobus?

Keratoglobus is a rare condition that affects the shape of the cornea, causing it to become abnormally thin and bulge outward in a rounded shape. This can lead to significant visual impairment and discomfort for those affected by the condition. In some cases, Keratoglobus can progress and become more severe over time, potentially requiring specialized care and treatment to manage the symptoms and preserve vision. Regular eye exams and monitoring are important for individuals with Keratoglobus to ensure proper management of the condition.

What Are The Causes Of Keratoglobus?

Keratoglobus is thought to be caused by a structural weakness in the cornea, leading to a gradual thinning and bulging of the cornea over time. This weakening may be due to a variety of factors, including genetic predisposition, collagen disorders, or excessive eye rubbing. The exact cause of Keratoglobus is not fully understood, but research suggests that a combination of genetic and environmental factors may play a role in its development.

What Are The Risk Factors For Keratoglobus?

Patients with Keratoglobus may have an increased risk for developing other eye conditions such as keratoconus, corneal thinning, and corneal scarring. These risks can lead to vision impairment and decreased visual acuity. Additionally, individuals with Keratoglobus may be more prone to experiencing discomfort and irritation in their eyes due to the irregular shape of the cornea. Regular monitoring and management by an eye care professional are essential to address these potential risks and prevent further complications.

What Are The Symptoms Of Keratoglobus?

Symptoms of Keratoglobus may include blurred or distorted vision, extreme nearsightedness, astigmatism, and difficulty wearing contact lenses. Patients with Keratoglobus may also experience sensitivity to light, eye redness, and frequent changes in prescription eyewear. Additionally, individuals with this condition may notice a bulging appearance of the cornea, which can lead to discomfort and visual disturbances. Early detection and management of Keratoglobus are essential in order to prevent further complications and preserve vision.

How is Keratoglobus Diagnosed?

Keratoglobus is typically diagnosed through a comprehensive eye examination by an optometrist or ophthalmologist. During the exam, the eye care provider will carefully examine the shape and structure of the cornea using specialized equipment and techniques. This may include measuring the curvature of the cornea, assessing the thickness of the cornea, and evaluating the overall health of the eye. In some cases, additional tests such as corneal topography or imaging studies may be necessary to confirm a diagnosis of Keratoglobus. It is important to seek prompt evaluation by an eye care professional if you suspect you may have Keratoglobus or are experiencing changes in your vision or eye health.

How is Keratoglobus Treated?

Keratoglobus is typically treated through a combination of specialized contact lenses and surgical interventions. For individuals with mild cases, rigid gas permeable contact lenses can help to improve vision by providing a more uniform surface for light to pass through the cornea. In more severe cases, surgical procedures such as corneal collagen cross-linking or corneal transplant may be necessary to stabilize the cornea and improve vision. These treatments aim to reduce the progression of Keratoglobus and address any vision impairments that may result from the condition. It is important for individuals with Keratoglobus to work closely with their eye care provider to determine the most appropriate treatment plan for their specific needs.

Is There A Cure For Keratoglobus?

Unfortunately, there is currently no cure for Keratoglobus. However, there are treatment options available to help manage the condition and improve vision. These may include prescription eyeglasses or contact lenses to correct vision, as well as specialized contact lenses or scleral lenses to help reshape the cornea and improve visual acuity. In some cases, surgical interventions such as corneal transplant may be necessary to restore vision and improve quality of life for individuals with Keratoglobus. It is important for patients with Keratoglobus to work closely with their eye care provider to determine the best treatment plan for their individual needs.

How Can Keratoglobus Be Prevented?

Keratoglobus cannot be prevented, as it is a congenital condition that is present from birth. However, regular eye exams can help to detect any changes in the shape of the cornea early on, which can help in managing the condition and preventing any complications that may arise. Additionally, protecting the eyes from injury and trauma can help to prevent any exacerbation of Keratoglobus. It is important to consult with an optometrist or ophthalmologist for proper evaluation and management of this condition.
