The exact cause of keratoconus is not fully understood, but it is thought to involve a combination of genetic susceptibility and environmental factors. The corneal tissue becomes mechanically weaker, allowing it to thin and bulge forwards.
Risk factors and contributors
Frequent eye rubbing, allergy or atopy and a family history of keratoconus all appear to increase risk. Certain systemic conditions and connective tissue disorders are also reported more often in people with keratoconus.
- Stopping eye rubbing is strongly advised in anyone with keratoconus
- Managing allergy and dry eye can help reduce irritation
- Relatives may be offered corneal topography screening
- Progression is monitored so that cross-linking can be offered at the right time
