Keratoconus is the commonest condition in a family of disorders called the corneal ectasias. Other members of the family include keratoglobus and pellucid marginal degeneration.
The word Keratoconus is formed by two Greek words: kerato, meaning cornea, and konos, meaning cone. Keratoconus affects approximately 1 in 2000 of the population, presenting mainly in the late teens or early 20s and remains the commonest indication for corneal transplantation in this age group.
Keratoconus itself is a condition in which the shape of the cornea, which is usually curved like a football, is distorted, developing a cone-shaped bulge, similar to that of a rugby ball, resulting in reduced vision. Progression of the condition depends on many factors but includes the age at the time of the onset. The earlier the onset, the faster keratoconus progresses.
The condition is almost always bilateral and asymmetric - meaning that it affects both eyes, however one eye may be more affected than the other.
What causes Keratoconus?
The cause of Keratoconus is unknown. We do however, know several risk factors including hereditry factors, eye rubbing, certain underlying disorders such as Downs Syndrome. Individuals often suffer from allergic eye disease. Keratoconus treatment
- Eyeglasses in the early stages.
- Rigid contact lenses: when eyeglasses do not work
- CXL - Corneal Collagen Cross linking with Riboflavin - increases the strength of the cornea to prevent progress
- Intracorneal rings (Intacs and Ferrara)
- Corneal transplant: in advanced stages - either a partial thickness (Deep Anterior Lamellar or DALK) or full thickness (Penetrating or PK).
