The abnormal shape makes it difficult for the eye to focus light waves. Keratoconus symptoms often begin in the late teenage years or early 20s.
Below, we provide keratoconus causes and risk factors.
High Risk Factors for Keratoconus
There are several factors that may increase your risk of developing keratoconus. For example, if you have a family history of Down syndrome or keratoconus, you have a higher risk for the condition.
Other risk factors for keratoconus include:
- Chronic eye inflammation. If you have allergies, irritants can damage corneal tissue, possibly resulting in keratoconus.
- Eye rubbing. Constantly rubbing your eye can damage the corneal tissue and can also affect the progression of keratoconus.
- Age. Keratoconus symptoms typically emerge from the teenage years through the early 20s. Young patients with advanced symptoms often need surgery to treat the condition.
You can also take certain steps to delay or prevent keratoconus.
Other Keratoconus Causes
According to the National Keratoconus Foundation, allergies, oxidative stress and hormones may also play a role in whether you develop keratoconus.
Allergies Can Cause Keratoconus
If you have allergies, you may tend to rub your eyes. Unfortunately, vigorous eye rubbing can exacerbate irritation and itching. Many people with keratoconus have conditions such as asthma, hay fever, eczema, and food allergies, which are commonly referred to as atopic diseases. Those diagnosed with keratoconus should avoid rubbing their eyes whenever possible.
Keratoconus Causes from Oxidative Stress
Oxidative stress describes physiological strain on the body due to free radicals that are not neutralized by antioxidants in your eyes. To put it more plainly, if you have keratoconus, your corneas cannot repair themselves very well. So, routine damage to your corneal tissue fails to heal, leading to more advanced stages of the disease.
The cornea, like other body tissues, creates byproducts or waste, known as free radicals. When they work normally, your corneas destroy free radicals before they can damage your eye’s collagen, which holds the tissue together. Free radical damage can cause the cornea to bulge and thin. Additionally, accumulated free radicals can lead to further damage that affects your vision.
Hormonal Keratoconus Causes
Keratoconus often begins to develop during puberty. So, some researchers believe that the endocrine system may play a role in the development of this disease. However, more studies are required to prove this theory and translate it to actionable treatment.
