The One Secret Optometrists Want Everyone to Know

Are you ready for the big secret?

Well, here it is… Annual comprehensive eye exams are not just about your vision! These yearly visits are ALSO your best chance at early detection of over 270 non-eye related diseases including cancers, autoimmune diseases,
stroke risk, high blood pressure and more.

Wow! How is this possible? Eye doctors are the only health professionals that can see into the back of the eye to investigate the health of the blood vessels and optic nerve, which can uncover a lot about your eyes and general health. In fact, many of the 270+ diseases that can be detected in an eye exam can be detected by an eye doctor before symptoms show up. This means that early detection of a disease can give the patient and healthcare team the ability to treat, manage and slow progression before quality of life is impacted.

“We want every Coloradan to know that when you skip your annual eye exam you’re putting more than your eyesight at risk. An annual eye exam is truly your best chance at early detection for general health challenges that can impact patients at any age. It’s a simple 30–60-minute appointment that has saved lives. Don’t skip this exam,” says Dr. Jean DeMoss, President of the Colorado Optometric Association’s Board of Directors.  

Can I Just Get a Quick Screening?
A vision screening is simply a tool used to determine if you should see an eye doctor for a comprehensive exam and is not effective at detecting potential eye health issues. A vision screening does not detect or diagnose any vision or health issues and does not replace a comprehensive eye exam with an optometrist. This means if you have only been getting vision screenings then you will want to schedule a comprehensive exam with an optometrist soon.

Common Health Conditions Optometrists Can Detect

  • Autoimmune diseases (lupus, multiple sclerosis, rheumatoid arthritis)
  • Certain cancers (blood, skin, tissue)
  • Brain tumors
  • Diabetes
  • High blood pressure
  • High cholesterol
  • Heart disease
  • Sjögren’s syndrome
  • Stroke risk
  • Thyroid disease

Diabetic Eye Health: 5 Ways to Protect Your Eyesight

Did you know that both type 1 and 2 diabetes can damage your eyes and cause vision loss? That’s right, the primary cause of blindness in adults ages 20-74 is diabetes.1 In fact, damage can be occurring for years without symptoms. This makes an optometrist an essential part of your healthcare team.

Diabetes patients are not only at risk for diabetic retinopathy, but they are at higher risk to develop cataracts earlier and glaucoma. In fact, early detection and treatment of diabetic retinopathy can reduce the risk of blindness by 95%.1 It’s estimated that 50% of individuals with diabetes will develop diabetic retinopathy at some point and everyone with diabetes is at risk for this eye disease.

5 Ways to Avoid Diabetic Eye Disease

  1. Attending Annual Comprehensive Diabetic Eye Exams – This eye exam takes about 30 minutes and is similar to a standard comprehensive eye exam. Your eye doctor will dilate your eyes and focus on the health of your retina and the blood vessels in each eye. Only an eye doctor can perform these exams and they may advise you to increase or decrease your exam frequency depending on how well your blood sugar is being controlled. The eye doctor will report their findings to your primary care doctor.
  2. Controlling Blood Sugar – High blood sugar can damage the blood vessels in the back of your eyes over time and the damage can begin as early as pre-diabetes. Keep your blood sugar under control to lower your risk of eye health related issues.
  3. Controlling Blood Pressure – High blood pressure impacts two-thirds of diabetes patients and increases your risk of retinopathy along with stroke and heart attack. Work with your primary care doctor to manage your blood pressure and reduce the risk of diabetic eye diseases.
  4. Controlling Cholesterol – Diabetes can impact cholesterol levels by reducing “good” cholesterol and increasing “bad” cholesterol, which increases the risk of diabetic retinopathy. Managing cholesterol levels is important for overall health and eye health.
  5. Don’t Smoke – The sobering truth is that smoking increases everyone’s risk of developing type 2 diabetes.3 For individuals who use insulin, smoking can reduce the effectiveness of insulin requiring more to manage blood sugar and increasing the risk of diabetic eye conditions.4 Free help to quit, call 1-800-QUIT NOW (1-800-784-8669) or visit gov/tips.

Common Diabetic Eye Diseases

  • Diabetic Retinopathy is when there is damage to the blood vessels in the back of the eye. This damage can cause blur or distortion in your vision, increase in floaters and permanent vision loss if severe.
  • Diabetic Macular Edema is swelling in the macula, which is the part of the retina responsible for your central vision.
  • Glaucoma is caused by increased pressure in the eye, which can damage the optic nerve and can cause peripheral vision loss before noticeable symptoms occur.
  • Cataracts are changes in color or clarity of the lens inside your eye that can cause blurry, cloudy or decreased vision.

Call your optometrist immediately if you have diabetes and experience any of these symptoms:

  • Blurry vision
  • Black spots
  • More floaters than usual
  • Feeling like a curtain is pulled over your visual field
  • Flashes of light
  • Any loss of sight in one or both eyes


Should I Go to the ER for an Eye Emergency?

If you had an eye health emergency today, do you know where to go for the best and most efficient care? We’ve all had health emergencies arise at one point in time and in most cases rushing to the urgent care or emergency room is appropriate. However, if the health issue is regarding your eyes or vision you may want to rethink your emergency plan. Eye doctors are prepared to treat most eye care emergencies in office and many eye doctors also have after hours care for these emergent eye care cases.

One study found that 25% of ocular ER visits were deemed non-emergencies and could have been handled in-office by an eye doctor. This means that patients paid a higher cost to be seen in the ER  by a general healthcare provider rather than making an appointment with their eye doctor or utilizing the eye doctor’s emergent after-hours care. Individuals were 10% less likely to seek care in an ER for an eye condition if they had an established eye doctor.1 Don’t have an eye doctor? Find a Colorado eye doctor here.

Call your eye care provider first to see if you should be seen by your optometrist or if your situation is better addressed in the emergency department or urgent care. Seeing your eye doctor for an eye emergency is usually best because:

  • Many emergency rooms and urgent care facilities lack the proper equipment for proper eye exams
  • In an emergency room or urgent care facility you will probably see a general health practitioner rather than a specialized eye care professional like your optometrist
  • Misdiagnosis could impact your vision and eye health permanently

“To get the best eye care in an emergency, we recommend that you have an eye health emergency plan. Eye care is essential so it’s important to have an optometrist that you see annually who can also address any eye care issues or emergencies that arise between your annual exams. Make sure your loved ones also have an eye care emergency plan for their own eye health,” says Dr. Jean DeMoss, President of the Colorado Optometric Association’s Board of Directors.

Blunt Eye Trauma

  • Apply a cold compress without putting pressure on the eye to reduce pain and swelling.
  • Severe pain or reduced vision require immediate care from an eye doctor.

Eye Cut, Puncture or Foreign Body to the Eye or Eyelid

  • Do not attempt to remove an object from your eye or eyelid.
  • Do not wash out the eye for punctures, cuts or foreign bodies.
  • Do not bandage the eye.
  • Do not rub the eye.
  • Protect the eye with a rigid shield, like sunglasses or the bottom half of a paper cup and see an eye doctor immediately.

Chemical Burn of the Eye

  • Flush eye(s) thoroughly with saline (preferably) or water for 15 minutes and get to an eye care professional immediately.
  • For individuals with contact lenses, attempt to remove them first.
  • Do not try to neutralize the chemical with another chemical or substance.

Sudden Vision Changes or Loss

Address quickly with your optometrist to avoid permanent vision loss and rule out more serious health issues like stroke, nerve damage, neurological issues, and retinal or corneal defects.

Red Eye

  • Red eye with discharge needs to be examined by an optometrist as soon as possible for correct identification and treatment for the type of conjunctivitis (pink eye). Emergency rooms have a history of overprescribing antibiotics for conjunctivitis when 80% of cases are viral.
  • Red eye could also indicate uveitis or ocular herpes, which can be sight-threatening making quick and proper evaluation by an eye doctor important.

Pupils are Different Sizes (pupil anisocoria)

  • If you were born with this condition it is benign.
  • If this is a new symptom, whether it’s constant or sporadic, schedule an exam with your optometrist as soon as possible as this could be vision threatening.
