What is Keratoconus?

Keratoconus (from Greek: kerato- horn, cornea; and konos cone) is a degenerative disorder of the eye in which structural changes within the cornea cause it to thin and change to a more conical shape than its normal gradual curve. Grossly the eye is more ‘cone’ shaped rather than the usual football or rugby ball shape.

Keratoconus can cause substantial distortion of vision, with multiple images, streaking and sensitivity to light. If afflicting both eyes, the deterioration in vision can affect the patient’s ability to drive a car or read normal print.

It is typically diagnosed in the adolescent years and attains its most severe state by the age of 30 (although this is variable).

Keratoconus affects around one person in a thousand. It seems to occur in populations throughout the world, although it is observed more frequently in certain ethnic groups, such as Asians. Environmental and genetic factors are considered possible causes, but the exact cause is uncertain. It is more common in patients with asthma, eczema and hayfever.
