(HealthDay)-Cataracts are a common eye disease that often occurs with age and may also be associated with an increased risk of death from heart disease, new studies show.
Experts emphasized that this finding does not mean that cataracts cause heart problems in any way, and that the study is not designed to prove the cause and effect.
“Various medical conditions like [high blood pressure]Dr. Matthew Gorsky, an ophthalmologist at Northwell Health in Great Neck, New York, believes that cataracts may be important. But the underlying health signal.
“Patients, especially when you get older, or when you have a particular medical condition, the results of this study to remind you of the importance of having regular eye examinations with your ophthalmologist. Should be used, “said Gorski, who was not involved in the new study.
The study was conducted in Australia and was led by Dr. Mingguang He of the Australian Center for Ophthalmology Research, University of Melbourne. His team analyzed data obtained from approximately 15,000 American patients over the age of 40 between 1999 and 2008. More than 2,000 people (9.6%) Cataract surgery..
The median follow-up was about 11 years, with nearly 4,000 (19%) of participants dying.
After considering the number of health and socio-economic factors, researchers found that: dangerous of death The risk of death from any cause is 13% higher Heart disease 36% higher than those who had Cataract Surgery.
Oxidative stress (an imbalance in the natural oxidative process that affects cells) and depression can be common factors that affect the formation of cataracts and can increase the risk of death from heart disease. Yes, his team said in their study.
The author of the study pointed out a previous study. Oxidative stress It contributes to the formation of cataracts and at the same time causes unhealthy stenosis of the arteries.
People with cataracts are more likely to develop depression than people without eye condition, and people with depression are at risk of heart disease, according to an Australian team. It will be higher.
Overall, the study “found a significant association between self-reported cataract surgery and an increased risk of death from all causes, especially heart-related causes,” the authors said.
Dr. Mark Frommer is an ophthalmologist at Lenox Hill Hospital in New York City. “It’s certainly not surprising to expect cataract patients to have other underlying disorders, as most cataract patients are elderly,” he said after reading the findings.
Fromer said people usually surgically remove cataracts at an earlier age than decades ago. “This has allowed patients to live longer after surgery than reported just a few decades ago,” he said. “See better follow Surgery It also improves quality of life and prevents accidents that can lead to death or injury due to poor eyesight. “
This study was conducted on October 25th British Journal of Offtalmology..
