Keratoconus is a progressive eye disorder that affects the shape and structure of the cornea, the clear front surface of the eye. It is characterized by the thinning and bulging of the cornea, leading to a cone-like shape instead of its normal round shape. This abnormality causes visual distortion and can result in significant vision impairment.
There are several synonyms used to describe keratoconus, which include:
- Conical cornea: This term refers to the cone-shaped cornea that is characteristic of keratoconus. The cornea becomes progressively thinner and bulges outward, leading to visual disturbances.
- Corneal ectasia: This synonym is often used to describe the abnormal thinning and bulging of the cornea in keratoconus. Ectasia refers to the stretching or protrusion of a tissue.
- Keratoglobus: This term is used to describe a more severe form of keratoconus where the entire cornea becomes thin and bulges, resulting in a globular shape. It is a rare condition but shares similarities with keratoconus.
- Corneal hydrops: This synonym is used to describe a complication of keratoconus where fluid accumulates in the cornea, causing sudden and severe swelling. It can lead to a sudden decrease in vision and requires immediate medical attention.
It is important to note that while these terms are used interchangeably with keratoconus, they all refer to the same underlying condition affecting the cornea. Early detection and proper management of keratoconus are crucial in preserving vision and preventing further deterioration.
