What is a congenital enlargement of the cornea called?

• A. Keratoconus
• B. Keratoglobus
• C. Cataract
• D. Corneal abrasion

Answer: (B)

The correct term for a congenital enlargement of the cornea is indeed keratoglobus. This condition is characterized by a generalized bulging of the cornea, which can result in visual impairment due to the irregular shape affecting the way light enters the eye. Unlike keratoconus, which involves a localized thinning and conical protrusion of the cornea, keratoglobus presents as a more uniform, globe-like expansion. Cataracts refer to the clouding of the lens inside the eye, which can lead to vision loss but does not involve the cornea directly. A corneal abrasion is an injury to the cornea's surface layer, often resulting from trauma and not a congenital condition. Each of these conditions has specific clinical implications and characteristics that differentiate them from keratoglobus, making it essential to understand their definitions and how they manifest.
