Your Eyes Are the Windows to Your Health

Your eyes aren't just the windows to your soul — they can also reveal valuable information about your general health beyond whether you need glasses, including: diabetes, heart disease, and even cancer. It is not unusual for people to come in for an eye exam just to check their eyesight and then have certain health issues or predispositions picked up by the optometrist. 

Eye Exams and Your Health

Eye examinations can help doctors detect general health conditions early enough to intervene. Advanced screenings enable eye doctors to better predict cardiovascular incidents like stroke, and possibly detect signs of mental changes such as Alzheimer's. Read below to learn how eye exams can unveil a whole lot more than just eye health.

Brain Cancer & Stroke

Because of the similarities between the blood vessels in the eye and brain, an eye doctor can occasionally detect an issue taking place in the brain by examining the blood vessels in the eyes. If swelling or shadows in the eye is observed, it may indicate a serious condition in the brain, like a tumor, or clots that might result in a stroke.

Diabetes

Diabetes can cause damage to the blood vessels in the retina at the back of the eye, resulting in Diabetic Retinopathy (DR) and Diabetic Macular Edema (DME). If an optometrist detects leaky blood vessels in the eye, the patient would be advised to see a doctor to help control their blood sugar. Changes are gradual, and they start before visual symptoms are noticed. The earlier diabetic eye disease is managed, the better the chances are of preserving eyesight. 

Hypertension

High blood pressure, characterized by having too much pressure in the blood vessels, can be detected during an eye exam, sometimes even before it's diagnosed by your regular doctor. The damaged blood vessels lead to swelling, hemorrhages, and leaking — all of which can be observed in the eyes. According to the CDC, hypertension "the silent killer" affects nearly 1 in 3 adults, and up to a whopping 20% of those don't even know they have it. So early detection at an eye doctor's evaluation can be truly life-saving.

High Cholesterol 

Eye exams can also detect a buildup of cholesterol. High cholesterol is among the easiest conditions to spot during a complete eye exam, as the cholesterol deposits manifest on the front of the eye, appearing as a thin, gray rim around the cornea. It can also be detected in the retina by assessing artery and vein patterns.

These deposits may indicate the current or future development of Retinal Blood Vessel Occlusion, a condition where blockages restrict blood flow to the back of the eye, causing temporary or permanent vision loss. 

Heart Conditions

In some cases, heart conditions associated with a buildup of plaque in the carotid artery in the heart can also lead to deposits that clog the ocular arteries in the eye. If an optometrist detects such changes to the vascular structure at the back of the eye, he or she will typically recommend going to a specialist.

Multiple Sclerosis (MS)

Sudden vision loss may be attributed to Multiple Sclerosis (MS). While the optometrist can recognize signs indicating the presence of MS, such as the color and appearance of the optic nerve, such cases will be referred for further testing to confirm the diagnosis.

Thyroid

Thyroid disease can make itself apparent through the eyes in several ways. The thyroid gland controls the hormones that regulate tear production so some thyroid disorders can cause dry eye disease. Additionally, overactive thyroid (hyperthyroidism) can make the extraocular muscles enlarge and stiffen, causing bulging eyes — an indicator of Graves' disease. 

Inflammation

Systemic conditions that are associated with inflammation in the body can have an inflammatory effect on the eyes. Uveitis, for example, causes eye inflammation, redness, and blurred vision, and tends to occur in people with lupus, rheumatoid arthritis, and other autoimmune diseases. 

Cancer

Breast cancer, leukemia, and other metastatic cancers are occasionally discovered during an eye evaluation. In addition to brain cancer mentioned above, melanoma and basal cell carcinoma (skin cancer) can be detected, and eye doctors can also diagnose lymphoma and other eye tumors. Eye exams save lives.

What the Future Holds 

Alzheimer's 

Recent studies show that a non-invasive and precise imaging device called Octa (optical coherence tomography angiography) can signal the presence of eye changes associated with Alzheimer's disease. Because the retina is in many ways an extension of the brain, the altered blood vessels at the back of the eye offer a glimpse into the changes taking place within the brain.

Parkinson's Disease

Parkinson's Disease can often be misdiagnosed as its early symptoms are characteristic of other conditions. Research has shown that subtle eye tremors, an early Parkinson's marker, could be detectable using advanced eye exam technology. One day soon, practitioners may send patients to an eye doctor to test for this and other diseases.

Your Eye Doctor's Appointment Could Change Your Life

So the next time you visit Dr. Richard M. Shetzline at Eye Associates of Richboro in Richboro, remember that a comprehensive eye exam can do more than determine your eyeglasses or contacts prescription. Dr. Richard M. Shetzline can evaluate your eyes for existing or potential health issues, and communicate them to your primary care physician for the best possible care. By knowing that you're at risk for a certain disease, you can take precautions early on and manage the condition as needed. After all, an ounce of prevention is worth a pound of cure.

We are taking every measure to assure the safety of patients, our doctors and our staff. We are closely monitoring and following guidance from the CDC and local health officials. We provide essential medical care and will remain open to care for our patients. Rest assured we have taken every precaution to prevent the spread of infectious disease in our offices.

In every office we continue to strictly adhere to hygiene and infection control protocols as we always have. We have reinforced staff training in basic and advanced hygiene and confirmed our cleaning and disinfection techniques are consistent with CDC recommendations.

We have increased our surveillance of patients who have scheduled appointments. All patient who receive patient appointment reminders are advised of the following:

If you returned from outside the U.S or visited an area defined by the CDC as an area of high risk IN THE LAST 14 DAYS, OR

If you had direct contact with an individual with confirmed coronavirus (COVID-19) IN THE LAST 14 DAYS, OR,

If you had direct contact with a person who is currently being quarantined for coronavirus (COVID-19) exposure IN THE LAST 14 DAYS, OR,

If you felt feverish and had a cough in the last 24 hours, please call our office to reschedule your appointment.

We are also confirming all appointments with a live phone call to further enhance our ability to identify patients at risk.

In addition, at the entrance of each office location we have posted a sign in English and Spanish repeating the message above.

Our computer based check in system once again queries each patient with the above questions.

All patients entering the office will have their body temperature measured with non-contact thermometers.

To the extent possible we will attempt to limit close contact between patients in the reception area by suggesting seating arrangements that avoid close contact.

Any patient who enters the office and is identified as at risk will be immediately masked and isolated while we contact the NJ Department of Health for further guidance. Our staff has been educated on this procedure and each office is supplied with appropriate personal protective equipment (PPE) for our staff.

Our goal is to be diligent in protecting patients, doctors and staff from unnecessary exposure while continuing to provide them medical care they need.

This is a rapidly evolving situation and we will change our processes as necessary. We encourage you to adopt similar procedures in your own office and to stay well informed of recommendations from the CDC with respect to the COVID-19 Virus.
