Cataracts

Risk factors for cataracts

Most people who develop cataracts are 40 or older. A variety of factors, including being African American or Latino American, may increase your chances of developing cataracts at an earlier age. Other cataract risk factors include:

  • Use of certain medications (such as corticosteroids and statins for cholesterol)

  • Diabetes

  • Eye injury, surgery or radiation treatments in the past

  • Having close relatives with cataracts

  • Heavy alcohol consumption

  • High blood pressure

  • History of eye inflammation

  • Hormone replacement therapy (HRT)

  • Obesity

  • Severe nearsightedness (high myopia)

  • Smoking

  • Spending a lot of time outside in the sun without sunglasses

Study Reveals Eye Care Disparities for Native American Patients

https://jamanetwork.com/journals/jamaophthalmology/article-abstract/2787498

Their analysis revealed that Native American patients had “significantly different” claim rates in 16 of 17 ophthalmic condition categories and 6 of 9 service categories compared with non-Hispanic White patients. More specifically, there were higher ophthalmic condition claim rates but lower service claim rates for Native American patients for:

  • Refractive errors (ophthalmic condition, 17.2 vs 11.1; service, 48.3 vs 49.6, respectively; P <.001)

  • Blindness and low vision (ophthalmic condition, 1.48 vs 0.75; service, 19.2 vs 20.1, respectively; P <.001)

  • Injury, burns, and surgical complications (ophthalmic condition, 1.8 vs 1.7; service, 19.2 vs 20.1, respectively; P <.001)

  • Orbital and external disease (ophthalmic condition, 15.7 vs 13.3; service, 48.3 vs 49.6, respectively; P < .001)

In addition, Native American patients had higher ophthalmic condition claim rates for diabetic eye diseases compared with non-Hispanic White individuals (5.22 vs 2.20), but no difference in service claim rates (14.4 vs 14.8; P =.26), according to researchers.

Conclusions and Relevance In this cross-sectional study, North American Native individuals had higher prevalence of ophthalmic conditions but no corresponding increase in services (treatment for most ophthalmic conditions) compared with non-Hispanic White individuals. These results suggest worse eye health and higher unmet eyecare needs for North American Native individuals with MFFS coverage compared with non-Hispanic White individuals with MFFS coverage.


How to reduce your risk of cataracts

There is no way to stop cataracts from developing. But here are steps you can take that may postpone or slow the development of cataracts:

  • Eat a healthy diet and get regular exercise

  • Get regular eye exams

  • If you're a smoker, make a plan to kick the habit

  • Wear sunglasses with 100% UV protection

  • Use floppy hats as well to protect your face from the sun

  • Visit your doctor regularly and keep other conditions under control (diabetes, hypertension)
