Keratoconus often has a hereditary component, meaning it can run in families, but inheritance patterns are complex. Not everyone with a family history will develop the condition.
Genetic Influence
Research shows that close relatives of someone with keratoconus have a higher risk than the general population. Multiple genes are thought to contribute, each adding a small amount to overall susceptibility.
- Family history increases risk but does not guarantee disease
- Some systemic conditions are associated more frequently with keratoconus
- Environmental factors such as eye rubbing also play a role
Screening Family Members
Because early keratoconus can be subtle, relativesespecially teenagers and young adultsmay benefit from periodic corneal topography. Early detection allows timely cross-linking if progression is seen.
