Keratoglobus
Keratoglobus
Keratoglobus (pronounced: ker-uh-toh-gloh-buhs) is a rare, non-inflammatory, bilateral corneal ectasia, which results in the thinning and globular protrusion of the cornea. The term is derived from the Greek words 'kerato', meaning cornea, and 'globus', meaning globe.
Definition
Keratoglobus is a corneal dystrophy characterized by a generalized thinning and globular protrusion of the cornea, leading to a globular appearance of the cornea. It is a rare condition, often present from birth, and can lead to significant visual impairment.
Symptoms
The main symptoms of keratoglobus include myopia, astigmatism, and photophobia. In severe cases, the cornea may rupture, leading to a sudden decrease in vision and severe pain.
Causes
The exact cause of keratoglobus is unknown. However, it is believed to be associated with certain genetic disorders such as Ehlers-Danlos syndrome and Blue sclera syndrome.
Diagnosis
Diagnosis of keratoglobus is typically made through a comprehensive eye examination, including slit-lamp examination and corneal topography.
Treatment
Treatment options for keratoglobus include corneal collagen cross-linking, keratoplasty, and the use of scleral contact lenses. In severe cases, a corneal transplant may be necessary.
