Glaucoma and Vision Loss: Am I At Risk of Going Blind?

Baptist Eye Surgeons • May 3, 2021

You can live with glaucoma for years without even knowing it. While it can take years for the effects to become noticeable, vision loss due to glaucoma is permanent even with treatment. It’s essential that you start getting comprehensive exams as soon as possible to monitor the progress of the disease and retain what eyesight you still have.

Cases of blindness due to glaucoma are relatively rare but still possible. Knowing your risk factors and seeking immediate treatment are the first steps for retaining your vision. Glaucoma attacks the optic nerve, slowly resulting in the loss of your peripheral vision. Treatment is available in the form of eye drops, oral medications, and surgery.

Does glaucoma cause blindness?

Yes , glaucoma can cause blindness if left untreated . Fortunately, this is fairly rare with only around 5% of glaucoma patients experiencing blindness. A bigger concern is the estimated 10% of glaucoma patients who experience permanent vision reduction due to the disease. 

So how long does it take to go blind without glaucoma treatment? This is a much more difficult question to answer. The progression from glaucoma to blindness is often slow and gradual. However, the rate that you experience vision loss will depend on a variety of risk factors.

Risk Factors for Glaucoma

There are a few factors that can significantly increase your risk of developing glaucoma. They include:

  • Age
  • Race
  • Genetics
  • Medical history

Age is one of the most significant risk factors for developing glaucoma. As you get older, your risk only goes up. This is especially true for people over the age of 60. However, African Americans face an increased risk starting at age 40.

Race also plays an important role in your risk of developing glaucoma. For instance, African Americans are around five times more likely to develop glaucoma than others. Hispanics face an increased risk regardless of age, while those of Native American and Asian descent have a higher chance of developing angle-closure glaucoma.

Your own genetics can help determine your risk of glaucoma. Talk to relatives and establish your family history. Make sure to alert your doctor if you have any parents, siblings, or other relatives with this particular disease. Alternatively, make sure to let them know if you get diagnosed so they can get checked, as well.

Knowing your own medical history can also help establish your risk. For example, high blood pressure, nearsightedness, previous eye injuries, and long-term steroid use all increase your risk for glaucoma. Talk to your eye doctor about what other personal medical issues may increase your risk.

It’s important to learn your risk factors early and talk about them with your doctor. You can’t prevent glaucoma, but your doctor will be able to develop a treatment plan that helps control your symptoms and lets you continue living the life that you love. 

What is glaucoma?

Glaucoma is an eye disease that causes damage to the optic nerve. This damage can go unnoticed for a long time, but the effects are irreversible. As glaucoma damages the optic nerve, peripheral vision is lost, making it more difficult to see objects without directly looking at them. While experts aren’t sure of the exact cause, glaucoma is often connected to high eye pressure. 

When healthy, a water liquid known as aqueous humor is constantly flowing into and out of the eye. Unfortunately, the drainage system can act as a sink and become clogged, resulting in increased eye pressure ( intraocular pressure ). Increased pressure within the eye causes the nerve fibers in the eye to die, resulting in decreased vision or even blindness.

There are different types of glaucoma with some being more common than others. They include:

  • Open-angle glaucoma
  • Angle-closure glaucoma 
  • Normal-tension glaucoma
  • Congenital glaucoma

Open-angle glaucoma is the most common and makes up 90% of cases. Angle-closure glaucoma is more rare and develops quicker than other types. Normal-tension glaucoma is unique in that it damages the optic nerve without very high eye pressure. Congenital glaucoma is present at birth and is very rare.

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.
