Blurred Vision And Heart Problems

Eyes May Offer Window Into Cardiovascular Disease

What causes sudden blurred vision?

Vision problems may sometimes be the only symptom a person has of a serious cardiovascular condition, a new case report suggests.

In the case, a 77-year-old man in Greece experienced three short episodes of blurred vision in his right eye. The five-minute episodes stretched over an hour in total, and after each episode, his vision returned to normal.

Concerned about this sudden problem, the man went to the eye clinic at his local hospital.

An eye exam showed that the man’s vision was good, and the pressure within his eyes was normal. But when the man’s pupils were dilated and a doctor looked more closely into his eyes, the culprit was revealed: A blood clot was blocking the blood supply in a branch of his retinal artery, which supplies blood to the lining at the back of the eye, according to the report of the man’s case.

Such clots are typically made out of cholesterol and clumps of platelets , and in the case, the clot came from the man’s carotid artery, the main artery that brings blood to the head and neck, said Dr. Ilias Georgalas, an assistant professor of ophthalmology at the National and Kapodistrian University of Athens, in Greece.

But the tiny clot was a serious health problem people with a blockage in the eye’s central or branch retinal artery have a high risk of a serious or fatal stroke, said Georgalas, who treated the man and was one of the co-authors of the case report published online today in the New England Journal of Medicine.

Congestive Heart Failure And Eye Effects

2/1/2022

How well your cardiovascular system functions can impact your overall health, including your vision and eye health. February is American Heart Month. It is the perfect reminder to take care of our heart health and lower our risk of different cardiac conditions. For instance, congestive heart failure is one condition that can impact your vision.The article below takes a look at what CHF involves and how it may impact vision and treatment options.

Why Do I Have Blurry Vision When I’m Tired

You may have eye strain from reading or staring at a backlit screen. Blurry vision may come from the muscles of the eye tiring out and becoming unable to focus. You may need glasses or contact lenses, or you may need to close your eyes for a period of time to rest. It is recommended that if your work involves screen time that lasts for at least 10 minutes every hour, take some time to focus on something farther away wherever you’re working to give your eyes some rest.

Could It Be Psoriasis

You may know this condition from these symptoms:

But psoriasis can affect your eyes, too. It can cause a condition called uveitis, when inflammation leads to swelling that causes blurred vision, pain, redness, and sensitivity to light.

Treatments can get rid of uveitis, but the type you need will depend on which part of your eye is affected. Learn more about uveitis.

Could It Be A Migraine

A migraine is more than a horrible headache. There are a host of other symptoms that you might have with the pain, including blurry vision and sensitivity to light. You may feel these signs even before a migraine starts, and they may last until it’s over.

More dramatic changes to your eyesight during a migraine are called an aura. They can include:

  • Loss of part or all of your vision for a little while
  • Seeing flashes of light
  • Seeing flashes of light
  • Seeing wavy lines or spots

To solve these problems, you’ll need to work with your doctor to treat your migraines and keep them from starting. Learn more about migraine headaches with aura.

Yellow Bumps Around The Eyes: Xanthelasmas

Some middle-aged and older adults develop soft, yellowish, cholesterol-filled bumps on or around their eyelids, most commonly near the nose . Called xanthelasmas, these small growths arent painful and rarely affect vision. But they can be a sign of high levels of cholesterol, triglycerides, or other fats in the blood. Theyre somewhat more prevalent in women than men. People who have them should be sure to get a cholesterol test, also known as lipid test or lipid profile.

Illustration by Scott Leighton

Xanthelasmas are more common in people with genetic disorders that cause abnormally high cholesterol levels, such as familial hypercholesterolemia, which can cause LDL cholesterol levels of 190 or higher.

If your LDL is elevated, regular exercise and a high-fiber, plant-based diet can help lower it. Many people need cholesterol-lowering drugs such as statins, which will sometimes but not always reduce the size of a xanthelasma.

Half of people with xanthelasmas have normal lipid levels, and the growths are simply a cosmetic problem. But people with a family history of early heart disease should make sure their physician know about this possible sign of heightened cardiovascular risk.

Presence Of Lesions Indicate Level Of Heart Disease Risk

The researchers findings were based on the review of records of people who received eye exams, also known as retinal optical coherence tomography scans, at UC San Diego Health between July 2014 and July 2019.

They were able to identify two groups after medical chart review: one that consisted of 84 people with heart disease and the other comprised on 76 health people who were used as the control group for the study.

The eyes of the individuals who had heart disease were found to have had more RIPLs and according to the researchers, the higher the RIPLs in the eye, the higher the risk of cardiovascular disease.

The only way we can visualize the smallest blood vessels in the body is in the eyes, explained Anthony DeMaria, MD, Judith and Jack White Chair in Cardiology and cardiologist at the University.

The retina in particular provides important evidence of the adverse effects of cardiovascular issues, such as high blood pressure, he added.

Could It Be Parkinson’s Disease

Blurry vision, brain fog, and increased ocular pressure, due to Intracranial Hypertension

Blurry vision is not the first sign of this nerve disease. But as it gets worse, it can affect sight. That’s because the condition may change how your eyes move. As your sight seems less sharp, you may strain your eyes because they have to work harder to focus.

Parkinson’s disease affects much more than the eyes. It also causes:

  • Poor balance and coordination

Early Eye Exams Can Mitigate Risk Of Future Strokes Heart Attacks

Its my hope that the presence of RIPLs in the eye will serve as a marker for cardiovascular disease when patients are undergoing assessment of risk factors for heart disease, or when patients are undergoing evaluation for the suspected presence of heart disease, said DeMaria.

Identifying RIPLs early on could help individuals seek early therapy and preventative measures, which in the long run, could mitigate the risk of future strokes and heart attacks.

Globally, cardiovascular disease is the number one cause of death and unfortunately many people are unaware they may have heart issues, said Bakhoum.The key in preventing this is early detection and treatment. Its our hope that by identifying RIPLs as a marker for cardiovascular disease providers will be able to identify heart issues before a catastrophic event, such as a heart attack or a stroke, occurs.

Fast Signs Of Strokewhat Are The Other Signs

The FAST signs are the most common signs of stroke and they are signs that are more likely to be caused by stroke than any other condition.

There are some additional signs of stroke that are less common.

They include:

  • Vision changes – blurred or double vision
  • Sudden severe headache – usually accompanied by some of the other signs
  • Numbness – usually on one side of the body
  • Problems with balance
What if I do not experience all of the FAST signs?

Not everyone will experience all of the signs of stroke. If you experience any of the FAST signs, call 9-1-1 immediately.

Are womens signs different than mens?

The signs of stroke are the same for men and women.

Do the FAST signs apply to hemorrhagic and mini-strokes ?

The FAST signs of stroke apply to ischemic, hemorrhagic, and mini-strokes, or TIA. There may be some differences in signs with each. For example, in the case of a hemorrhagic stroke, severe headache may occur in addition to some or all of the FAST signs. In the case of TIA, the signs may last for only a few minutes and usually last for less than one hour.

In all cases call 9-1-1 right away to ensure you are taken to the right hospital that provides acute stroke care.

Learn more about TIA.

Are doctors and paramedics aware of the FAST signs?
What can I expect at the hospital?

The paramedics will take you to the closest hospital with a specialized program for stroke care. They will call ahead so hospital staff is prepared for your arrival.

What The Doctor Does

Doctors first ask questions about the person’s symptoms and medical history. Doctors then do a physical examination. What they find during the history and physical examination often suggests a cause of the blurred vision and the tests that may need to be done .

Doctors ask many questions about the person’s symptoms because it is important to understand exactly what the person means by blurred vision. For example, people who have actually lost vision in part of their visual field may describe this sensation only as blurred vision. The presence of other eye symptoms, such as eye redness, sensitivity to light, floaters, a sensation of sudden flashes of light that can look like lightning, spots, or stars , and pain at rest or with eye movement, helps doctors determine the cause. Doctors also ask about the effects of darkness and bright lights and whether the person wears corrective lenses.

Doctors also ask questions about symptoms of possible causes and about the presence of disorders that are known to be risk factors for eye disorders .

Examination of the eyes may be all that is necessary.

Symptoms and findings during the eye examination often help suggest a cause. For example, if visual acuity returns while corrective lenses or a pinhole device is used and the remainder of the eye exam is normal, simple refractive error is usually the cause of blurring.

Natural Treatment For Blurred Vision

Can High Blood Pressure Cause Headaches And Blurred Vision ...

Eye conditions are the most common cause of blurred vision, but in some cases, the underlying cause can be related to your cardiovascular system. Low blood sugar, high blood pressure, and stroke can also affect your vision.

There are several natural ingredients you can try that will reduce the risk of these factors that can affect your heart and vision.

Low blood glucose: Blood glucose levels affect energy and heart health. Hypoglycemia can trigger heart palpitations, which can stress heart tissues and muscles. Naturally manage blood glucose levels with red yeast rice to prevent vision defects and damage to your heart.High blood pressure: Hypertension is one of the leading causes of a heart attack, stroke, and heart disease. Dietary and lifestyle changes can help blood pressure levels, and so can natural supplements. Studies have shown that red yeast rice and berberine bark extract naturally lower blood pressure. In addition to this, taking capsicum extract promotes blood vessel dilation and enhances circulation. Stroke: The risk of stroke increases with high cholesterol. Niacin, chromium, and pine bark extract are all proven to naturally lower cholesterol levels. In doing so, they reduce the risk of a stroke.

A Pulsating Pupil And A Leaky Heart Valve

When the hearts aortic valve doesnt close tightly , small amounts of blood leak backward into the heart instead of being pumped into the body. Symptoms typically include fatigue and breathlessness.

In severe cases, another possible sign is a rarely documented eye phenomenon: pupils that dilate and constrict in synchrony with the heartbeat. Called Landolfis sign, it was first described by Italian physician Michele Landolfi in 1909.

Compared with people who have normal hearts, people with aortic regurgitation have a wide pulse pressure, which means there is an unusually big difference between the two numbers in their blood pressure readings . The pupil pulsations reflect these large pressure fluctuations.

Conditions Related To Blurred Vision

The cone cells on the macula become damaged, leading to loss of central vision. There are two main types: dry AMD, which progresses slowly but is untreatable, and wet AMD, which progresses more rapidly but is treatable, especially if spotted early.

Cardiovascular disease

Blurred vision that occurs with double vision can be a sign of a health emergency, such as a brain haemorrhage or stroke.

A cataract is the gradual clouding of your lens, which is a transparent disc behind your iris . Its common in people over 65, though it can happen earlier. Besides blurred vision, symptoms include sensitivity to light and a dulling effect on colours. Luckily, its easily treated with cataract surgery.

Diabetes

Over time, diabetes can lead to a condition called retinopathy, when the tiny blood vessels at the back of your eye become blocked and leak. This damages your retina, which is essential for vision and can lead to sight loss. However, it can be prevented if detected early through regular screening.

There are four types of glaucoma, which can lead to a build-up of pressure in your eye, damaging the optic nerve. This can permanently damage your sight, especially your peripheral vision, but once its detected, sight loss can usually be prevented.

Your Eyes Can Reveal Your Heart Disease Status Heres How

Tala Michel Issa, Al Arabiya English

A new study finds that doctors may be able to detect whether you have cardiovascular disease or not through biomarkers present in eyes.

An eye exam may be able to show signs of cardiovascular disease through tiny lesions in eye retina, researchers at the Shiley Eye Institute at University of California San Diego Health have found.

The eyes are a window into our health, and many diseases can manifest in the eye cardiovascular disease is no exception, lead author of the study and physician-scientist and retina surgeon at UC San Diego Health Dr. Mathiew Bakhoum said in a statement published on the Universitys website.

Decreased blood flow caused by heart disease, known as Ischemia, can lead to inadequate blood flow to the eye and may cause cells in the retina to die, leaving behind a permanent mark, said Bakhoum.

We termed this mark retinal ischemic perivascular lesions, or RIPLs, and sought to determine if this finding could serve as a biomarker for cardiovascular disease.

Can Blurry Vision Be Caused By A Lack Of Sleep

Sudden Blurry Vision | What causes sudden blurred vision and what to do about it.

Generally no, but lack of sleep and eye fatigue are commonly associated and eye fatigue can cause blurry vision, especially in those without an adequate prescription for their eyes. As the body becomes sleepier, it becomes more difficult to focus the lens of the eye and the result is blurry vision or vision that takes a longer time to focus.

Can Anxiety Make You Dizzy

Dizziness, which includes symptoms like lightheadedness or vertigo, has many underlying causes including anxiety. In the same way that anxiety can affect the vision, adrenaline and cortisol released by the sympathetic nervous system can also have a direct impact on the vestibular system.

Vestibular problems are one of the leading causes of lightheadedness, vertigo, and other symptoms related to dizziness. When stress hormones are released, they can influence the balance of the cells within the vestibular system, leading to these symptoms.

Interestingly, dizziness can also cause trouble focusing visually, which may lead to the feeling of blurred vision.

Anxiety triggers the release of multiple stress hormones, causing a wide variety of symptoms, including visual symptoms. Although visual symptoms differ from person to person, anxiety may also cause:

Some of these visual symptoms, like tunnel vision and light sensitivity, may be more likely to appear more during acute anxiety episodes, like a panic attack. But many of these symptoms, like eye strain and eye twitching, are more likely associated with the long-term effects of excess stress and anxiety.

While some level of anxiety is normal and necessary in everyday life, sometimes anxiety can become chronic and intrusive. Anxiety disorders affect more than 40 million adults in the United States, according to the National Alliance on Mental Illness .
