What Causes Keratoconus?
The characteristics of keratoconus have been known for at least 200 years, but the specific causes are still undetermined. Several theories have been proposed:
- One scientific theory is that keratoconus is genetic in origin. About 7% of patients have other family members with the disease.
- Another view holds that keratoconus is a degenerative condition perhaps linked to the altered balance between enzymes and inhibitors within the cornea
- Keratoconus may also be secondary to some disease processes.
- A hypothesis has also been proposed that keratoconus may involve the endocrine system (hormones) since the condition is often diagnosed in young people at puberty or in their late teens.
While the exact cause of keratoconus has not yet been determined, research into keratoconus continues and new treatment options are continually under development.
