Risk Factors
The following factors increase your chance of developing corneal opacity. If you have any of these risk factors, tell your doctor:
- Vitamin A deficiency
- Measles (when measles result in scarring/infection of the eye)
- Foreign bodies striking the eye
- Eye injury, whether from a force, such as a poke in the eye, or from a chemical agent
- Herpes simplex virus (which can be transmitted to the eyes)
- Other infections, including conjunctivitis or "pink eye"
- Additionally, wearing contact lenses for a long period of time, especially overnight, can increase the risk of eye infections and, as a result, increase the chance of developing corneal opacity.
