Keratoglobus is a rare, non-inflammatory, bilateral eye disorder that results in a generalized thinning and globular protrusion of the cornea. This condition is typically present at birth and is characterized by a round, symmetrically enlarged cornea.

Symptoms

The symptoms of Keratoglobus can vary, but often include:

• Visual impairment
• Photophobia (sensitivity to light)
• Astigmatism
• Myopia (nearsightedness)

Causes

The exact cause of Keratoglobus is unknown, but it is believed to be associated with conditions such as:

• Ehlers-Danlos syndrome
• Blue sclera syndrome
• Marfan syndrome

Diagnosis

Diagnosis of Keratoglobus is typically made through a comprehensive eye examination. This may include:

• Slit lamp examination
• Corneal topography
• Optical coherence tomography

Treatment

Treatment options for Keratoglobus are limited and often challenging due to the thin and fragile nature of the cornea. They may include:

• Contact lenses
• Corneal transplant
• Keratoprosthesis

• Corneal ectasia
• Keratoconus
