Causes of Cataracts

A cataract is a cloudy area in the lens of the eye that interferes with normal vision. Although ophthalmologists do not know what biological mechanisms are responsible for the formation of cataracts, they have identified several potential causes and treatments for the condition. If you suspect you have cataracts, an ophthalmologist can determine the cause, offer a diagnosis, and review the cataract treatments available to you.

Risk Factors: What You Should Know about Cataracts and Their Potential Causes and Treatments

Ophthalmologists readily agree that environmental, lifestyle, and other factors can contribute to the formation of cataracts. And, although cataract treatments vary, avoiding exposure to the following contributing factors can limit the formation of cataracts:

• Ultraviolet Radiation (UVA or UVB)

  - Long-term exposure to ultraviolet radiation can cause changes in pigment that lead to the formation of cataracts. UVB is especially dangerous to the eyes.

• Free Radicals

  - High levels of free radicals within the body cause a chemical reaction that results in cell damage. This can lead to the formation of cataracts. Cataract treatments include identifying potential risk factors and limiting exposure.

• Medications

  - There are several drugs that can lead to cataract formation. The most well known are oral steroids. In addition, long-term aspirin use has been associated with cataracts. Other medications that have been linked to cataracts include tamoxifen (treats breast cancer), allopurinol (treats gout), and amiodarone (treats irregularities in heartbeat). If you are taking any of these medications, contact your ophthalmologist for alternative treatment options for cataract prevention and management.

• Smoking

  - Smoking has been targeted as a potential cataracts cause, and is suspected of leading to the formation of nuclear cataracts. There is some evidence to suggest that chemical byproducts of inhaled smoke are responsible for cataract formation. Ophthalmologists agree that it is critical for smokers with cataracts to quit smoking as part of their treatment.

• Alcohol

  - Scientists have been unable to determine if alcohol use is directly linked to protein in the eye, or if it is linked indirectly by blocking the absorption of essential nutrients, thereby creating a potential cataracts cause. Once again, cataract treatments vary, but ophthalmologists recommend that alcohol consumption be limited to moderate amounts for optimal eye health.

• Medical Disorders

  - There are several medical disorders that have been associated with the formation of cataracts. These include diabetes, glaucoma, and metabolic conditions.

• Physical Injury

  - Physical injuries, such as a blow to the eye, a cut, a puncture, intense heat or cold, chemical burns, or radiation therapy, can lead to cataract formation.
