The cataract causes vision to worsen because of a cloudy area in the lens. It is more common for one eye to develop cataracts than both. Symptoms include lack of color perception, double vision or blurry vision, halos around light, difficulty seeing at night, and trouble with bright lights.
The condition may make it difficult to read, drive, and recognize faces. An increased risk of falling and depression may also result from impaired vision caused by cataracts. Blindness and visual impairment worldwide are caused by cataracts, which account for half of all blindness cases.
Heart Disease Deaths Are Associated With Cataracts
The human body is a tremendous mechanism where various organs are connected with each other, and with different types of researches, the experts keep on revealing them. Many times clinicians find strange cases where they cannot find the exact reasons also.
In this latest research, the experts have found that there is a correlation between heart disease deaths and cataracts. It is a study carried out by experts in different regions as a team.
They have checked many samples from different ages and areas with a similar medical history and developed a model with the help of which this fact is revealed.
The risk of death from heart disease could also be higher if a person has cataracts, a common eye disorder that often comes with aging. The study was not designed to establish cause and effect, and experts emphasized that the finding does not imply cataracts cause heart trouble.
Ophthalmologist at Northwell Health in Great Neck, N.Y., Matthew Gorski, says smoking and diabetes increase cataracts, and these diseases also increase mortality due to vascular disease. Nonetheless, cataracts can be important health indicators.
According to Gorski, the study’s results are a reminder to patients to have regular eye exams with their doctors, especially when they are older or have certain medical conditions,” she said.
Dr. Mingguang was the principal investigator who worked at the University of Melbourne’s Centre for Eye Research Australia. More than 1,000 (9.5%) of the nearly 14,000 older American patients analyzed by his team had undergone cataract surgery between 1998 and 2009. Close to 3,000 participants (18%) have died over an average follow-up period of nearly ten years.
According to the researchers, even after taking into account a number of health and socioeconomic factors, cataract surgery patients have a 13% higher death rate from any cause and a 36% higher death rate from heart disease.
His group found that oxidative stress, which imbalances natural oxidation processes in cells, could lead to cataracts and increase a person’s risk of developing heart disease, according to their research.
As indicated by previous studies, oxidative stress can damage DNA, causing cataracts and eating away at the arteries.
An Australian research team found that even after cataract surgery, people with depression and heart problems show a higher risk of depression than people without eye problems.
As a result, “significant associations were identified” between self-reported cataract surgery and an increased risk of death of any kind, especially from heart-related causes, the authors said.
New York City ophthalmologist Mark Fromer practices at Lenox Hill Hospital. In reading over the findings, he concluded that “it is certainly not surprising that an elderly population with cataracts also has other underlying illnesses.”
It was noted in Former’s remarks that cataracts are usually removed sooner than they would have been a few decades ago. This has meant that patients live much longer than they did just decades ago, he said. The fact that you can see better following surgery also leads to a higher quality of life and may help you avoid accidents that may result in death or injury if you cannot see well.”
