Many people expect their eyesight to decline with age — perhaps requiring a stronger eyeglass prescription or “readers.” Some vision changes are linked to age, but there are steps to consider to help our eyes stay as healthy as possible.
Dr. Linda Chous, OD, chief eye care officer, UnitedHealthcare, answered the following questions:
1. Are my eyes going to keep getting worse as I age?
While your eyesight is not guaranteed to deteriorate with age, it is normal to notice changes to your vision as the years pass, including:
- Minor adjustments to your eyeglasses prescription or needing to use “readers” for the first time;
- Trouble distinguishing colors, such as blue from black; and
- The need for more light to see well.
Although these changes are often normal, they can also be signs of conditions like cataracts or even diabetes. It is important to maintain regular appointments with your eye doctor to help identify pressing concerns. If you experience sudden vision loss or any rapid change to your eyesight, contact your eye care provider immediately.
2. What are the tiny spots or specks that float across my vision?
These tiny threads of protein float across the gel-like substance between your eye’s lens and retina.
Usually there is no need to worry if you notice these spots occasionally and they disappear after a few minutes, but only a dilated eye examination can determine the cause of the “floaters.”
If your vision is overcome by these specks or you notice vision loss, contact your eye doctor, as it could be a symptom of a sight-threatening condition.
3. What are some common vision-related diseases that come with age?
Age-related macular degeneration (AMD)
AMD is the leading cause of vision loss in people over 65. AMD causes damage to the macula, the small spot on the retina that enables people to see clearly and view things straight ahead of them.
Common symptoms are distortion and blurring of the center of your field of vision. If caught early, there are potential benefits from certain prescription medications and nutritional supplements. Late-stage AMD is much more difficult to treat.
Certain factors like heredity, ultraviolet light exposure and smoking may increase the risk of AMD. Consult with your eye doctor to determine if a preventive treatment plan is right for you.
A cataract is the clouding of the lens in your eye, blocking the flow of light to the back of your eye (retina), which ultimately causes loss of sight. Most form slowly and do not cause pain. Significant clouding can form in some people and, ultimately, negatively impact vision.
Cataracts are treatable via surgery that replaces the clouded lens with a clear plastic lens. Cataract surgery is generally safe and one of the most common surgeries in the U.S. Once a cataract is removed, it cannot grow back.
Glaucoma is caused by increased pressure inside the eye, which can cause permanent vision loss and blindness if untreated. The most common form usually has no noticeable symptoms in the early stages — the only way to detect it is routine testing.
Treatment may include prescription eye drops, oral medications, laser treatment surgery or a combination of any of these. It is important to find glaucoma early because once vision is lost, it cannot be regained.
4. What are the best ways to keep my eyes healthy as I age?
Some of the best ways to protect your eyes include:
- Stop smoking. Smokers are up to four times more likely to develop AMD and may contribute to development of cataracts.
- Maintain a healthy weight. Conditions associated with being overweight, like diabetes and heart disease, increase your risk of vision loss from cataracts, glaucoma and retinopathy.
- Wear sunglasses. Help protect your eyes from harmful ultraviolet rays.
- Be physically active. People who are physically active experienced less vision loss over 20 years compared to those who are less active.
- Eat a healthy diet. Colorful fruits and vegetables contain nutrients that can keep your eyes healthy and reduce AMD risk.
5. Do sunglasses really protect my eyes?
Sunglasses act as a buffer between your eyes and the sun’s ultraviolet (UV) rays. Exposure to these rays can put you at greater risk of cataracts and AMD. Look for a pair that blocks 99% to 100% of UV rays.
Note that polarization is different from UV protection; however, most polarized sunglasses also provide UV protection. Check the product tag or ask for assistance in choosing the right pair.
6. How often should I see my eye care doctor?
Eye exams are crucial to maintaining eye health as you age. Many eye diseases, like glaucoma, have no symptoms in early stages. And many systemic conditions, such as diabetes and high blood pressure, can be first found during a routine eye exam. Aim to see your eye doctor annually even if your vision hasn’t changed, so your doctor has a record of your eye health. See your doctor immediately for sudden changes.

Left Ventricular Aneurysm Surgery
A heart aneurysm is a serious illness that causes impairment of the contractile activity of the affected area of the heart muscle. Most often such pathology develops in the wall of the left ventricle of the heart. The disease more often affects men over the age of 40. Aneurysm detected in the heart grows only up to a certain size, but always requires surgical treatment.
Treatment for left ventricular aneurysm
Today physicians cope with heart aneurysms only by surgery. This is the only effective method that can completely cure a patient. Medication therapy is only used to temporarily improve the condition of patients with left ventricular aneurysms. If a patient is diagnosed with a left ventricular aneurysm, urgent surgical treatment is prescribed in the presence of the following indications:
- Severe heart rhythm abnormalities
- Formation of a blood clot in the aneurysm
- Rapidly developing heart failure
- Aneurysm rupture
Surgical treatment of acute and subacute heart aneurysms is indicated in the rapid progression of heart failure and the threat of aneurysmatic sac rupture. In chronic cardiac aneurysm, surgery is performed to prevent thromboembolic complications and for myocardial revascularization.
As a palliative intervention, strengthening of the aneurysm wall with polymeric materials is resorted to. Radical operations include ventricular aneurysm resection (if necessary – with subsequent reconstruction of the myocardial wall).
How is the surgical treatment carried out?
During this procedure, the patient’s chest is opened and the blood flow through the heart is stopped. A special device is attached to the main vessels, which continues to maintain the pumping function while the heart remains inactive. Only then a surgeon removes the aneurysm. Vascular bypass is also performed, if necessary. After a cardiac aneurysm is excised, the treatment process is not over. After the operation, it is necessary to stay under the supervision of healthcare professionals, because there is a risk of complications.
In a post-traumatic aneurysm of the heart, the heart wall is sutured. If additional revascularizing intervention is necessary, aneurysm resection with CABG are performed simultaneously.
In the preoperative period, patients with a left ventricular aneurysm receive cardiac glycosides, anticoagulants, hypotensive drugs, and oxygen therapy.
As a rule, small left ventricular aneurysms do not require special methods of repair after the procedure. The defect after aneurysmectomy can be closed by a simple linear suture, which is effective and the most suitable option for such situations.
After left ventricular aneurysmectomy and possible plasty, the development of low ejection syndrome, repeated myocardial infarction, arrhythmias (paroxysmal tachycardia, atrial fibrillation), suture failure and bleeding, respiratory failure, renal failure, cerebral thromboembolism is possible.
Is it worth going abroad for treatment during a lockdown?
All of the above conditions pose a serious threat to a person’s life, so the start of treatment should not be delayed. Left ventricular aneurysm surgery should only be performed by an experienced physician because it is a very complex intervention. And the absence of timeliness and quality of the intervention becomes the reason why people go abroad to treat left ventricular aneurysms.
You might think that it isn’t worth jumping straight into it in the middle of a lockdown. But if you need to go abroad for treatment, you can. Yes, you may need to wait a bit longer to get a visa, but it also doesn’t have to be that way.

WHO urges caution over travel bans linked to new COVID-19 variant
The UN health agency has urged all countries to adopt a risk-based and scientific approach to travel bans linked to a new COVID-19 variant identified in South Africa and Botswana.
According to WHO’s COVID-19 technical lead, Dr. Maria Van Kerkhove the information is still limited.
“There are fewer than 100 whole genome sequences that are available, we don’t know very much about this yet. What we do know is that this variant has a large number of mutations, and the concern is that when you have so many mutations it can have an impact on how the virus behaves”, she said during a Q&A on Twitter.
Dr. Van Kerkhove explained that researchers are currently trying to determine where the mutations are and what they potentially mean for diagnostics, therapeutics, and vaccines.
“It will take a few weeks for us to understand what impact this variant has, there’s a lot of work that is underway. It’s a variant that’s under monitoring. The (WHO) technical advisory group will discuss if it will become a variant of interest or a variant of concern and if that’s the case, we will give it a Greek name, but it is something to watch”, she added.
‘Do not discriminate’
The expert thanked researchers from South Africa and Botswana for openly sharing information to the UN health agency.
“Everyone out there: do not discriminate against countries that share their findings openly”, she urged, as countries such as Britain, France and Israel have moved to cancel direct flights from South Africa and surrounding nations.
According to South African health authorities so far fewer than 100 cases of the new variant have been confirmed, largely among young people who have the lowest vaccination rate in the country.
“Countries can do a lot already in terms of surveillance and sequencing and work together with the affected countries or globally and scientifically to fight this variant and understand more about it so that we know how to go about…so at this point implementing travel measures is being cautioned against”, WHO spokesperson Christian Lindmeier told journalists in Geneva.
Protect yourself and others
The WHO officials reminded previous advice: people can do a lot to protect themselves from COVID, including by continuing to wear masks and avoiding crowds.
“Everybody that’s out there needs to understand that the more this virus circulates the more opportunities the virus has to change, the more mutations we will see”, said Dr. Van Kerkhove.
“Get vaccinated when you can, make sure you receive the full course of your doses and make sure you take steps to reduce your exposure and prevent yourself from passing that virus to someone else”, she added.
Tobacco use continues to fall, but still ‘long way to go’
The number of tobacco users continues to decrease globally, going from 1.32 billion in 2015 to 1.30 billion last year, the World Health Organization (WHO) said onTuesday.
And according to the fourth WHO global tobacco trends report, that number is expected to continue to drop to 1.27 billion by 2025.
Sixty countries are now on track to achieving the voluntary global target of a 30% per cent reduction by 2025, an increase from two years ago, when only 32 countries were on course.
For WHO Director-General Tedros Ghebreyesus, the numbers are very encouraging, but more work must be done.
“We still have a long way to go, and tobacco companies will continue to use every trick in the book to defend the gigantic profits they make from peddling their deadly wares”, Tedros said.
According to WHO, recent evidence shows that the tobacco industry used the COVID-19 pandemic to build influence with Governments in 80 States.
The report urges Member States to accelerate implementation of the measures outlined in the WHO Framework Convention on Tobacco Control (WHO FCTC).
Ruediger Krech, Director of WHO Department of Health Promotion, attributed some of the progress to measures aligned with the WHO FCTC, while maintaining that success is “fragile.”
“It is clear that tobacco control is effective, and we have a moral obligation to our people to move aggressively in order to achieve the Sustainable Development Goals (SDG) link”, he said.
A newly released WHO Global Investment Case for Tobacco Cessation, also makes the case for investing in cessation interventions.
According to the report, contributing US$ 1.68 per capita each year to national toll-free quit lines, SMS-based support, and other interventions could help 152 million tobacco users successfully quit by 2030.
The report and the investment case were released right after the ninth session of the Conference of the Parties to the Protocol to Eliminate Illicit Trade in Tobacco Products.Protocol to Eliminate Illicit Trade in Tobacco Products.
Last year, 22.3% per cent of the global population used tobacco, 36.7 per cent of all men and 7.8 per cent of the world’s women.
Approximately 38 million children between the ages of 13 and 15 currently use tobacco, 13 million girls and 25 million boys. While it is illegal for minors to purchase it, the goal is to achieve zero child tobacco users.
On average, upper middle-income countries are making the slowest progress, but with data quality low or insufficient in 29 countries, more monitoring is needed to assess a trend.
Of all WHO regions, the steepest decline is in the Americas, where the average user rate dropped from 21 per cent in 2010 to 16 per cent last year.
In Africa, the rate fell from 15 per cent to 10 per cent and the continent continues to have the lowest numbers.
In Europe, 18% per cent of women still use tobacco, substantially more than in any other WHO region, while all others are on track to reduce women’s usage rates by at least 30% per cent by 2025.
Although South-East Asia has the highest rates, with around 432 million users or 29 per cent of its population, it is also the region in which the numbers are declining fastest.
Finally, the Western Pacific is projected to become the region with the highest use among men, with indications showing that more than 45% per cent will still be using tobacco in 2025.
According to WHO, this product kills more than 8 eight million people each year, over 7 seven million of whom die as a direct result of smoking tobacco while around 1.2 million others from second-hand smoke.
