The Real Reason You Should Schedule a Dilated Eye Exam

Baptist Eye Surgeons • June 1, 2021

Eye exams are just as important as visiting your doctor or dentist. Unfortunately, many people don’t realize that eye exams are about more than updating your eyewear prescription. Dilated eye exams provide eye doctors with a deeper understanding of your vision health, overall health, and steps that need to be taken to protect you.

Dilated eye exams shine a light on a variety of vision and other health-related issues. Cataracts, glaucoma, and macular degeneration can all lead to significant vision loss if not checked regularly. Dilated eye exams also pick up on other health problems such as hypertension, diabetes, and autoimmune disorders that can affect your overall health.

Why You Need a Dilated Eye Exam

Dilated eye exams provide our surgeons with a more in-depth look at your visual health. More importantly, they also give your ophthalmologist a look at your overall health. This makes them an essential part of your preventative health routine, and just as important as your annual physical and regular dental checkups.

Many vision and other health problems don’t show signs or symptoms in their early stages. Additionally, a lot of vision problems are the most treatable in their early stages, but you need to take the proper steps to ensure that eye conditions are caught in order to receive treatment. Doing so will not only protect your vision, but other aspects of your health as well.

With a dilated eye exam, your ophthalmologist can detect early signs of:

  • Cataracts
  • Glaucoma
  • Macular degeneration
  • Hypertension
  • Diabetes
  • Autoimmune disorders

If you’re diagnosed with any of these conditions, our team can work with you to develop a treatment plan. This will help you receive the treatment you need to preserve your vision, and allows our team to track any changes that may occur. For signs that it’s time to schedule your next comprehensive eye exam, check out our recent blog.

Cataracts

Cataracts are the clouding of the crystalline lens in the eye. Located behind the pupil, your lens works with the cornea to focus light on the retina to create the images that you see. Cataracts are often described as a glare of filminess over the eye that causes vision to become dim or blurred.

Cataracts can take a long time to develop to this stage and can go unnoticed for years. With regular comprehensive eye exams (which include a dilated eye exam), our team of ophthalmologists can spot them early and provide the treatment you need.

Glaucoma

Glaucoma occurs when the optic nerve is damaged, usually due to high eye pressure. The optic nerve is what connects your eyeball to your brain, so it becoming damaged can cause severe vision loss if left untreated. 

According to the BrightFocus Foundation, over three million Americans over the age of 40 have some form of glaucoma. This makes it the leading cause of irreversible blindness in the United States as well as the world. Dilated eye exams are key to catching it and preventing its spread.

Macular Degeneration

Macular degeneration is the loss of central vision. This can make it difficult to see objects directly in front of you with them seeming blurred rather than clear. Macular degeneration is often associated with getting older, but it can also be the result of genetics. It’s not curable, but it can be treated and slowed down in certain cases. Dilated eye exams are essential for catching it early so you can receive treatment immediately. 

Hypertension

It can take years for symptoms of hypertension to manifest in your eyes, but they’re a clear sign to your eye doctor that something is wrong. Dilated eye exams act as a first line of defense against the “silent killer” of high blood pressure. They help you get the nutrition, exercise, and medication you need to avoid a heart attack and protect your vision.

Diabetes

High blood sugar damages your blood vessels including those in your eyes. It can cause diabetic retinopathy , which damages the blood vessels in your eyes and causes vision loss. Dilated eye exams catch microaneurysms early and prevent long-term damage to your retina. Click here to learn more about how we diagnose and treat diabetes-related eye conditions.

Autoimmune Disorders

Dilated eye exams can pick up on a variety of autoimmune disorders that may go undiagnosed. Autoimmune disorders can affect your eyes in different ways, but many of them have the same underlying symptoms — swelling and inflammation. Eye dilation allows our surgeons to see deep within the eye to detect these symptoms and get you the treatment you need.

What happens during a dilated eye exam?

Eye exams check a variety of factors related to your vision. This includes visual acuity, eye movement, depth perception, and many others. What makes dilated eye exams unique is that they “open up” your eyes to let more light in than normal. This allows our surgeons to get a clearer picture of your eye health and spot any problems that may be developing.

Dilated eye exams are essential for your vision and overall health. They give our eye surgeons a deeper picture of what’s happening in your eye and help them to spot issues such as cataracts, glaucoma, and macular degeneration. They can also help you get the treatment you need if you have hypertension, diabetes, autoimmune disorders, and much more.

Diabetes affects various parts of the body, including your eyes. Keeping your blood sugar under control is not just good for your health overall, but it also helps protect your eyesight. Over time, high blood sugar can irritate the tiny blood vessels in your eyes and increase your risk of serious eye problems. Knowing how diabetes and eye health are linked can help you identify issues and take measures to protect your sight. How Does Diabetes Affect Eye Health? When blood sugar stays high, it can damage the blood vessels in the retina, which is the part of your eye that senses light and helps you see. Damaged blood vessels might leak fluid, swell, or change how well the retina works. Diabetic eye problems usually develop slowly, so you might not pick up on any changes in your vision until significant damage has occurred. That’s why it’s important for people with diabetes to get regular eye exams, even if their eyesight seems fine. Common Eye Conditions Linked to Diabetes People with diabetes are more likely to have certain eye problems. Finding and treating these issues early can lower the chance of losing vision permanently. 1. Diabetic Retinopathy Diabetic retinopathy is a common eye issue that happens when high blood sugar damages the retinal blood vessels. These damaged vessels may leak fluid, which may cause blurry vision, dark spots, or changes in how you see. In advanced cases, abnormal blood vessel growth can lead to serious problems. If diabetic retinopathy worsens, new abnormal blood vessels can grow, causing serious problems, including vision loss. Getting regular eye exams can help catch these changes early, before they become severe. When fluid is retained in the macula (part of the retina which focuses on sharp central vision), this swelling can make it harder to read, recognize faces, or see fine details clearly. When detected early, treatments can help reduce swelling and protect your eyesight. 3. Cataracts People with diabetes have a higher chance of getting cataracts early. Cataracts occur when the lens in your eye becomes cloudy, which can cause blurry vision, increased sensitivity to glare, and difficulty seeing clearly. While cataracts come with age, having diabetes can make them appear sooner or progress quicker. 4. Glaucoma Diabetes can also raise your risk for glaucoma, which is a group of eye diseases that harm the optic nerve. Glaucoma usually starts without any clear symptoms, but if it is not treated, it can cause permanent vision loss. Routine regular eye exams are important for finding glaucoma early and keeping your eyes healthy Diabetes-related eye problems might not cause symptoms at first. Still, there are some warning signs you should look out for: • Blurry or distorted vision • Difficulty focusing • Dark spots, floaters, or shadows in your sight • Increased sensitivity to glare • Trouble seeing colors clearly • Sudden alterations in vision • Partial or complete loss of vision If you notice sudden vision changes, contact an eye doctor as soon as possible. The Value of Regular Eye Exams for People With Diabetes Getting a full eye exam is one of the best ways to protect your vision if you have diabetes. During the examination, your physician will study your retina, look for symptoms of diabetic eye disease, and track any changes over time. Many eye problems linked to diabetes can be treated more easily if they are found early. Regular checkups help your eye doctor give you advice that fits your own eye health and diabetes care. Protecting Your Eyes When You Have Diabetes Looking after your general health is important for keeping your eyes healthy. Here are some things you can do to protect your vision: • Keeping blood sugar levels under control • Managing blood pressure and cholesterol • Scheduling regular diabetic eye exams • Following your diabetes treatment plan • Eating a balanced diet that promotes eye health • Avoiding smoking, which increases the risk of eye complications Prioritizing Your Vision and Eye Health Diabetes and eye health are closely linked, but you can lower your risk of serious vision problems by taking action early. Getting regular eye exams, making healthy choices, and managing your diabetes all help protect your eyesight. If you have diabetes, seeing your eye doctor regularly can help catch changes early and keep your vision clear for the future. Your eyes are a key part of your health, so make caring for them a priority at every age.

Night vision problems can make everyday activities like driving at dusk, walking in poorly lit places, or adjusting to indoor lighting harder and sometimes unsafe. Trouble seeing in low light, called nyctalopia, is not a disease itself but a sign that something else may be affecting your eyes. Learning what causes night vision problems and when to get help is important for keeping your vision healthy. What Are Night Vision Problems? Night vision problems mean it is hard to see clearly in low light or darkness. Some people notice their eyes take longer to adjust when going from bright to dim places. Others may have trouble with glare from headlights, seeing less contrast, or things just looking dimmer at night. Mild changes in night vision can happen as you get older, but if your symptoms keep getting worse or do not go away, you should pay attention to them. Common Causes of Night Vision Difficulties There are several potential causes of night vision problems. Night vision problems can have many causes, from getting older to certain eye conditions, such as lens problems, leading to blurred vision and increased sensitivity to glare. They are one of the most common causes of poor night vision, especially in older adults. 1. Cataracts Cataracts cause clouding of the eye’s natural lens, leading to blurred vision and increased sensitivity to glare. They are one of the most common causes of poor night vision, especially in older adults. 2. Vitamin A Deficiency Vitamin A is important for keeping your retina healthy. If you do not get enough vitamin A, your eyes may have trouble adjusting to darkness, which can lead to night blindness. 3. Glaucoma Some types of glaucoma can affect your side vision and make it harder to see differences between light and dark. As the optic nerve gets damaged, seeing in low light can become more difficult. 4. Retinitis Pigmentosa This inherited eye condition slowly affects your ability to see at night and to the sides. Early signs often include trouble seeing in the dark. 5. Diabetes-Related Eye Disease Diabetic retinopathy can harm the blood vessels in your retina, which may cause blurry vision and make it harder to see at night. 6. Aging and Pupil Changes As people get older, their pupils do not react to light changes as quickly, and the retina becomes less sensitive. This naturally makes night vision worse over time. Symptoms to Watch For Night vision problems often develop slowly. Some common signs are: Difficulty seeing in low light or darkness Trouble driving at night due to glare from headlights Longer adjustment time when moving between light and dark environments Reduced contrast or clarity in dim settings Frequent squinting or eye strain in low light If these symptoms start to affect your daily life, it is a good idea to get a full eye check-up. When to See an Eye Doctor You should see an eye doctor if you notice new night vision problems, if they are getting worse, or if you have other changes in your vision. The doctor can run tests to find out what is causing the problem and suggest the right treatment. A full eye exam might include checking your retina, testing your field of vision, and taking images to look at your eye health. Finding problems early is very important for conditions like glaucoma, diabetic eye disease, and retinal disorders, because early treatment can help protect your vision. Protecting Your Night Vision Not all causes of night vision loss can be prevented, but taking care of your eyes can lower your risk and help you see better. Some helpful steps are: Scheduling regular eye exams Handling chronic health conditions like diabetes Eating a diet rich in vitamin A and antioxidants Wearing proper corrective lenses if prescribed Avoiding driving with untreated vision changes Prioritizing Your Eye Health Night vision problems can be an early sign of eye disease. Since many eye problems develop slowly, having regular eye exams is one of the best ways to catch changes early and keep your vision healthy for the long term. If you have trouble seeing at night or notice any changes in your vision, making an appointment for an eye exam can help keep your eyes healthy and your vision clear in all types of light.
