As another February comes to a close, so does another Heart Month. What
you may not know is the important roles vision problems and eye doctors
play in identifying heart health issues. Taking vision problems seriously
and having regular eye exams can make the difference between a healthy
heart and a life threatening health condition.
Key-Whitman patient avoids a stroke by taking visual symptoms seriously
A few months back, a patient in their mid-60s visited Key-Whitman Eye Center
in Dallas following a
transient ischemic attack (TIA). TIAs don’t cause permanent brain damage, but they are a key indicator
of heightened stroke risk. The patient had experienced dizziness and vision
problems with one eye during the TIA. By the time they came in to Key-Whitman,
they felt great, but that wasn’t the end of the story.
“We did a visual field test to check for vision loss, and there wasn’t
an issue. However, when we
performed the dilated eye exam, we could actually see a shiny piece of plaque that had broken off from
one of the blood vessels. By sheer luck, the blood flow was getting through,
but when we combined the plaque finding with the dizziness symptoms, our
alarm bells went off,”
says Key-Whitman President and Chief Surgeon Jeffrey Whitman, M.D.
After a visit to the patient’s internist, tests revealed a significant
stenosis and occlusion of the carotid arteries and the patient had surgery
the next week.
As Dr. Whitman elaborates, “So here was somebody who assuredly would
have had a stroke had they disregarded their temporary vision loss. That’s
why I tell patients, ‘Don’t sleep on it! Feel free to be a
worrywart, and don’t fear crying wolf.’ If you ignore the
DO have (or have had), and a week, a month, three months or a year go by,
that’s when something bad usually happens.”
Visual symptoms can point to hypertension and increased stroke risk
As Dr. Whitman explains, “When most people suffer from vision problems,
the first doctor they typically call is their eye doctor. What may surprise
those patients is certain vision symptoms actually indicate that hypertension
and an increased risk for stroke is likely.”
According to Dr. Whitman, the most common visual symptoms tied to an unhealthy
No. 1: Vision loss. When a patient complains of vision loss, any number of culprits could
be to blame. “What makes an eye doctor suspect vascular disease
is when reduced vision affects only one eye. Seldom is vision reduced
in both eyes when a patient has vascular disease,” Dr. Whitman says.
No. 2: Subconjunctival hemorrhage. Have you ever had a very subtle cough and ended up with a red blood spot
on the white part of your eye? According to Dr. Whitman, “That’s
what we call a subconjunctival hemorrhage, and those blood spots pop up
more frequently in people with uncontrolled blood pressure.”
No. 3: Headaches and double vision. “While rare, when a patient says they have a headache in conjunction
with double vision, that usually indicates the situation is critical and
the patient is at a heightened risk for a stroke,” Dr. Whitman says.
Unfortunately, many patients with heart disease have NO symptoms
That’s where an experienced eye care professional could save the
day. As Dr. Whitman explains, “It’s interesting, because we
frequently find vascular issues when people have no complaints. So you
could have hypertension with no visual finding and not be feeling anything
strange. This actually happens more frequently than having visual symptoms.”
While we’re not suggesting you skip regular physicals with your family
practitioner or internist, a trip to the eye doctor can reveal health
issues you had no idea existed.
Heart disease is but one of many health issues eye doctors find during eye exams
Dr. Whitman encourages patients to be diligent about getting annual eye
exams for this very reason. As he explains, “During an eye exam,
your eye doctor has the ability to pick up more than problems with hypertension,
stroke and cardiovascular disease. We also regularly find diabetes that
is out of control, glaucoma, cataracts and
other health and eye conditions.”
Many diseases – like heart disease – can linger for years absent
of any symptoms. “Without regular visits to your regular doctor
and eye doctor, they are powerless to pick up on and help prevent serious
health issues. If we can identify health problems early, we can help most
patients avoid bad health outcomes and permanent vision loss,” says
New technology aids diagnosis of vascular disease with less hassle
One of the standard procedures eye doctors perform during an annual eye
exam is to dilate the eye. This allows the doctor to take a close look
at the optic nerve and blood vessels in the back of the eye.
Many people dread the irritating drops used to dilate the eyes. Fortunately,
new technology, specifically the Optos Imaging system, doesn’t require drops.
As Dr. Whitman explains, “The Optos system allows us to take a non-dilated
digital image of the back of the eye, without the discomfort of dilating
drops. With the Optos technology, we can also perform a fluorescence test
to check for leaky blood vessels, a test that required a dye injection
in the past.”
So what warning signs do eye docs see during an eye exam?
Eye doctors look for a number of abnormalities during an annual eye exam.
“In particular, we look for blockage or deposits of calcium within
the blood vessels. Those don’t originate from the eye, but usually
come from the carotid arteries. Much of the time, the patient hasn’t
lost all vision, but part of the visual field,” says Dr. Whitman.
Vision loss may even come and go. When vision doesn’t come back, that patient may suffer permanent
vision loss. But it’s not only the patient’s vision that is at risk.
According to Dr. Whitman, “When we identify calcium or plaque in
the blood vessels of the eyes, we know the situation is serious and the
patient is at high risk for a stroke. That’s when a neurologist
or internist needs to enter the picture and perform intensive vascular
tests to look for stenosis or occlusions in the carotid arteries.
This is a critical time, because the coronary arteries, which supply blood
to the brain, have likely narrowed. If they occlude or throw a big clot,
they can clog up a major blood vessel and that can lead to a stroke.”
