Why Are Dilated Eye Exams So Important?

Having your eyes dilated may seem like a nuisance. But when you consider the benefits of a dilated examination, the temporary blurred vision and sensitivity to light that typically follow are definitely worth it.

What Are Dilated Eye Exams?

At some point during a comprehensive eye examination, your optometrist will shine a bright light into your eyes to examine the back of your eye, called the retina. The problem is that bright light causes the size of the pupil’s opening to shrink, which makes it hard for the optometrist to see a large portion of the retina.

That’s why we apply special eye drops in each eye to keep the pupils open. A dilated pupil allows for a much more accurate assessment of your eye’s structures, including the focusing lens, blood vessels and tissues at the back of the eye called the retina, as well as the optic nerve and macula.

Dilating the eyes makes it easier for your optometrist to detect the following conditions and diseases:

Cataracts
Glaucoma
Diabetic retinopathy
Macular degeneration
Retinal tumor
Retinal detachment or retinal tears
Eye floaters

It’s important to note that many of these conditions can develop without noticeable symptoms, until they cause vision loss at which point treatment may be more challenging, making dilated exams all the more crucial.

The Dilation Process

First, we will apply eye drops to each eye to trigger dilation of the pupil. Your eyes should be fully dilated about 10-20 minutes later.

Your eyes will remain dilated for 4-6 hours, and during this time you may be sensitive to light. That’s because the larger pupil allows more light than usual to enter the eye. Many patients find it more comfortable to wear sunglasses until their eyes return to normal.

Reading and using a computer may be difficult with dilated eyes, and your vision may be blurred. Some patients report feeling a tightening sensation in their eyelids, or headaches.

Dilated eye exams are a crucial part of keeping your eyes healthy. Advanced Eyecare also uses the Zeiss Clarus wide field camera to see the peripheral areas of the retina which can be prone to damage or detachment with such things as trauma, etc. To schedule your comprehensive eye examination, call Advanced Eyecare today!

6 Common Myths About Glaucoma

Glaucoma is an eye disease in which increased pressure causes progressive, permanent vision loss and even blindness. Unfortunately, many misconceptions about the disease can leave you misinformed. Below we sort fact from fiction by debunking 6 of the most common glaucoma myths.

Glaucoma Facts vs. Myths

MYTH 1: Glaucoma is a single disease

FACT

Glaucoma is a group of eye diseases; the most common ones are open-angle glaucoma (OAG) and angle-closure glaucoma (ACG).

In open-angle glaucoma, the drainage structure in your eye (called the trabecular meshwork) doesn’t allow the fluid inside the eye to flow out as it should, causing an increase in internal ocular pressure that damages the optic nerve. OAG develops slowly, and usually by the time people perceive symptoms, such as peripheral vision loss, they already have optic nerve damage.

In angle-closure glaucoma, the eye doesn’t drain fluid as it should because the drainage channel between your iris and cornea becomes too narrow, causing increased eye pressure. This pressure damages the optic nerve, leading to vision loss. ACG can occur suddenly or gradually. A lot of patients can have intermittent angle closure episodes which can cause pain.

MYTH 2: Only the elderly suffer from glaucoma

FACT

Although it’s true that people over 60 are at a greater risk of developing open-angle glaucoma compared to people in their 40s, there are other types of glaucoma that can affect people aged 20 to 50 and even young infants (due to abnormal ocular development).

In addition to age, those with a higher risk of developing glaucoma include:

African Americans and Hispanics
Individuals with a family history of glaucoma
Patients with cardiovascular disease, diabetes, or sickle cell anemia
Those who have previously sustained an eye injury
People taking steroid medications over the long term

MYTH 3: Glaucoma shows symptoms early on

FACT

The most common form of glaucoma, open-angle glaucoma, shows virtually no signs or symptoms until its later stages when vision loss occurs. Despite what people may think, the increased eye pressure usually causes no pain. And since peripheral vision is the first to go, you may not recognize vision loss until your vision has become significantly impaired. The only way to detect glaucoma is to undergo a comprehensive eye exam.

MYTH 4: Nothing can be done once you have glaucoma

FACT

While there’s currently no cure for glaucoma, many effective treatment options exist: eye drops, oral medications, as well as laser and surgical procedures that can help slow glaucoma progression. Each treatment option is used to get the fluid to flow properly out of the eye, reducing pressure inside the eye and decreasing damage to the optic nerve.

MYTH 5: Testing for glaucoma is painful

FACT

Actually, testing for glaucoma is essentially painless. One of the tests includes a non-contact device that tests the intraocular pressure. With certain tests an anesthetic eye drop is inserted into each eye, which may cause a stinging sensation for a few seconds. The most accurate of all, however, are visual field testing(peripheral vision testing with a computer) and OCT (optical coherence tomography which accurately makes a topographical map of the nerve), non-invasive imaging, both of which are also painless.

MYTH 6: You can’t prevent glaucoma

FACT

Although you can’t prevent glaucoma, regular eye exams are the only way to detect glaucoma, as blindness or significant vision loss can be prevented if the disease is diagnosed and treated in the early stages. That’s why routine comprehensive eye exams which include glaucoma testing are so important.

Getting your eyes checked regularly can ensure that any existing eye problems are detected early enough to prevent or slow ocular damage. Contact Advanced Eyecare to book your comprehensive eye exam today!

Frequently Asked Questions with Kraig Stasney, O.D.

Q: If one of my parents has glaucoma, does that mean I will develop it as well at some point?

A: Having a parent with glaucoma does not mean that the child will automatically develop the condition too. However, those people with an immediate family history (parents, siblings) of glaucoma are at more risk to develop this disease. Patients should have a comprehensive eye examination each year to evaluate the health of the eyes and to look for signs of glaucoma. Some of these signs can be an increase in the pressure of the eyes as well as changes to the appearance of the optic nerve. Many times there are no symptoms noticed by the patient. If there is suspicion of glaucoma, more frequent visits to the eye doctor along with additional nerve testing are often required.

Q: Why do I need to scan my retinas/back of the eye?

A: The retina shows us a lot about the overall ocular health as well as systemic conditions that can affect the eyes. Often diabetes, hypertension or high cholesterol can be observed from a retinal scan. Also, retinal scans allow us to diagnose and treat macular degeneration and glaucoma. Scans are often very important for a complete eye check up.

Does Obesity Impact Eye Health?

Nation-wide awareness about the vast dangers of obesity is at an all-time high.
Shows like “The Biggest Loser” and various health initiatives shine a spotlight on the importance of fitness and good nutrition. However, despite the public’s knowledge of obesity’s effects on hypertension, stroke, and diabetes, many are not aware of how it damages eye health and vision.

Increasing evidence shows that people who are clinically obese have an elevated risk of developing serious eye diseases. It is widely known that expanding waistlines place people at a higher risk of getting diabetes, heart disease, and cancer. Researchers say the link between obesity and deteriorating vision is the “risk factor that no one talks about”. Many health professionals found a consistently strong correlation between obesity and the development of four major eye diseases that may cause blindness:

Age-related macular degeneration (AMD)
Cataracts
Glaucoma
Diabetic retinopathy

These health research professionals said that although the evidence was out there suggesting a link between obesity and these conditions, their study emphasizes the ophthalmic risks of obesity which can help motivate people to shed those extra pounds.

How Obesity Contributes to Eye Disease

Serious eye conditions such as diabetic retinopathy, glaucoma, and age-related macular degeneration are more common in individuals with obesity, as well as floppy eyelid syndrome, retinal vein occlusions, thyroid-related eye diseases, and stroke-related vision loss.

The connection between obesity and these eye diseases is likely due to the increased risk of peripheral artery disease. This occurs when the tiny blood vessels bringing oxygen to parts of your body like the feet, kidneys, and eyes become compromised.

Your eyes are particularly prone to damage from obesity because the blood vessels in the eyes (called arterioles) are easily blocked, since they’re extremely thin and small — as thin as ½ the width of a human hair!

Most people are not aware that obesity may increase the rate of developing cataracts, too. Cataracts result when the focusing lens in the eye becomes cloudy and requires surgery to be replaced. In addition to age, cataract development is associated with obesity, poor nutrition, gout, diabetes and high blood sugar levels, though the exact cause isn’t clear.

A Healthy Lifestyle Can Reduce Your Risk of Ocular Disease

Knowing about the risk of vision loss may give those with a high BMI the extra motivational boost they need to lose weight. The good news is that a few lifestyle changes can reduce the associated risks.

An active lifestyle and a balanced, nutritious diet lower obesity and improve overall physical and eye health. Give your body a boost by incorporating important nutrients, such as vitamins C and E, zeaxanthin, omega 3, zinc, and lutein, many of which are found in green leafy and dark orange vegetables, as they have been shown to reduce the onset, progression, and severity of certain eye diseases.

The Doctors at Advanced Eyecare can Help Keep Your Eyes Healthy

While a healthy diet and regular exercise greatly increase your chances of living a disease-free long life, they alone are not enough to ensure long term healthy eyesight. Regular eye exams can help prevent or detect the onset of ocular disease, and maintain vision that is clear and comfortable.
