Is your eyesight gradually getting weaker? This could be due to Optic Atrophy!

Do you sometimes feel like your vision is a little blurry or blurry? You may think that this is normal, that it is just a matter of straining your eyes. However, sometimes this can be a sign of something more serious. Today we are going to talk about a condition called optic atrophy , which affects our vision. Don't worry, we will talk about this in a simple way that you can understand.

What exactly is Optic Atrophy?

Simply put, Optic Atrophy is when the cells in your optic nerve are damaged and gradually destroyed. The word “atrophy” means something that is deteriorating, weakening, or fading. So what happens in this case is the weakening of the optic nerve, which acts like a telephone wire that carries messages between our eyes and brain. This is a really serious condition .

Think of it this way: our eyes are like a camera. The optic nerve takes the image (visual information) from the camera and tells the brain, “This is what you see.” So if this nerve is damaged, it’s as if the wire carrying the message has been cut. Then, even though the eye sees, the information doesn’t go to the brain, so we have vision problems . This can sometimes lead to complete loss of vision, which can lead to blindness . Also, the biggest problem here is that this damage is often irreversible, meaning it can’t be restored .

What symptoms would we experience if we developed this?

Optic Atrophy is the main symptom of vision problems. Check to see if you have these symptoms:

• Vision becomes blurred and things become blurry: Letters and images that were previously clearly visible may now appear a little blurry and unclear. It's like a camera's focus has gone out of focus.
• Peripheral vision loss : Even though you can see straight ahead, you may lose your ability to see things to the sides of your eyes. It can feel like you're losing your peripheral vision, like a horse.
• Color blindness: Some colors, especially red and green, may be difficult to distinguish. Colors may appear slightly faded or even a different color.

If you have one or more of these symptoms, don't ignore them . It's important to see an eye doctor as soon as possible.

Why do we develop Optic Atrophy? What are the causes?

There are a number of reasons why this optic nerve can be damaged. That is, something interferes with the message traveling through the optic nerve to the brain. Let's look at the main causes:

• Lack of blood flow to the optic nerve (Vascular/Ischemia): This is the most common cause . Like every part of our body, the optic nerve also needs blood to function. It gets oxygen and nutrients from blood. So if this blood flow is disrupted, the nerve cells start to die.
• Congenital or hereditary conditions: Some people are born with these conditions. For example, a condition called Leber hereditary optic neuropathy can cause vision loss in one eye first, and then affect the other eye.
• Extrinsic/Intrinsic compression: Imagine a brain tumor pressing on the optic nerve. That can also damage the nerve. Similarly, in a condition called glaucoma , the pressure inside the eye can increase and damage the optic nerve.
• Inflammation caused by other diseases or the nerve itself: Optic neuritis is one cause. It can also be caused by conditions such as hydrocephalus , which is a buildup of fluid in the brain.
• Infections: Some infections can also damage the optic nerve. For example, diseases like syphilis and measles .
• Trauma/Eye injury: Imagine if you were hit in the eye by a ball while playing cricket, or if you were injured in a car accident, even something like this can damage the optic nerve and cause this condition. This also includes accidents at work, during fights.
• Diseases of the retina: Conditions such as diabetes-related retinopathy and retinal vein occlusion can also affect the optic nerve.
• Toxins, nutritional deficits, or medications: This condition can be caused by the ingestion of certain toxins, a lack of essential nutrients like vitamins, or as a side effect of certain medications. These causes often affect both eyes.

Is this a contagious disease?

No, Optic Atrophy is not a disease that can be transmitted from one person to another . However, as we discussed earlier, this condition can be caused by certain infections . That is, if the infection is contagious, it is possible that optic atrophy will occur as a result. Here are some infections that can cause this:

• Syphilis
• Measles
• Tuberculosis
• Mumps
• Chickenpox
• Lyme disease
• Aspergillosis (especially in immunocompromised individuals)
• Cryptococcosis (especially in immunocompromised individuals)

What is the danger of this condition? Or what are the complications?

As we mentioned earlier, damage to the optic nerve due to optic atrophy is usually very difficult to reverse, that is, to cure . That is the biggest complication here. The main thing that can happen is that vision gradually decreases, and eventually, complete loss of vision, that is, blindness.

Remember: If you lose your vision due to this condition, it is very difficult to regain it. That is why it is important to seek medical advice as soon as symptoms appear.

How does a doctor diagnose this exactly?

If you experience any changes or discomfort in your vision, you should definitely see an ophthalmologist . The doctor will first ask you about your symptoms, whether anyone in your family has had similar conditions, and your overall health. He may also ask about the foods, medications, and vitamins you take. Then, he will carefully examine your eyes.

What tests are being done for this?

During an eye exam, your doctor will look inside your eye using an instrument called an ophthalmoscope . When you look inside the eye of someone with optic atrophy, the optic disc may appear pale or discolored . This is because the nerve cells are damaged and the blood supply to them is reduced.

The doctor may also perform other tests to find out what is causing the condition (for example, a brain tumor or a disease of the nervous system, such as ``Multiple Sclerosis''). Some of these include:

• Optical Coherence Tomography (OCT): This can see the thickness of the layers of the optic nerve and retina.
• Visual field tests: A test that measures how far you can see around you.
• Magnetic Resonance Imaging (MRI) Scan: Can take clear pictures of the brain and optic nerve.
• Fluorescein angiography: A test to look at the condition of the blood vessels inside the eye.
• Ultrasound tests.
• Blood tests: To detect things like infections and nutritional deficiencies.

What are the treatments for this? Can it be completely cured?

Unfortunately, there is currently no cure for optic atrophy . This means that it is difficult to restore damaged optic nerve cells. That is why we always say to take care of your eyes, get regular eye exams, and see a doctor if you notice any changes in your vision.

However, doctors try to find the cause of the condition and treat it . In doing so, they try to stop or reduce further damage to the optic nerve. For example:

• If this is due to a brain tumor, surgery can be performed to remove the tumor.
• If there is fluid accumulation on the brain (hydrocephalus), there are ways to remove that fluid.
• In the case of glaucoma, medication can be given to reduce eye pressure.
• If it is due to an infection, antibiotics can be given.

Can we prevent this from happening?

In most cases, it is difficult for us to completely prevent Optic Atrophy. Because many of the factors that cause it are beyond our control. However, in some cases, there are things we can do to reduce our risk. For example:

• Wearing safety glasses to avoid eye injuries: Be especially careful when doing things like metalwork, woodwork, and playing sports.
• Getting the necessary vaccinations on time: This helps protect against infections like measles.
• Practice safe sex: Avoid sexually transmitted diseases like syphilis.
• If you have diseases like diabetes and high blood pressure, control them well.

If I have this condition, what will happen in the future?

The future of someone with this condition, that is, what their vision will be like , depends on what causes it .

• If this is caused by inflammation of the optic nerve (optic neuritis), most of the time, vision will return to some degree once the inflammation subsides.
• If the optic nerve is damaged for another reason (optic neuropathy), vision may not improve.
• If glaucoma is diagnosed and treated quickly ,, further deterioration of vision can be controlled.
• If it is something like a brain tumor, if it is identified and treated quickly , the pressure on the optic nerve can be reduced and further damage can be prevented.

If your vision is poor, don't give up hope . Talk to your doctor and ask about low vision aids . There are things like special lenses, magnifying glasses, and text-reading software.

When should I see a doctor about this?

It's important to have your eyes checked regularly , especially if you have other eye conditions. Also, be sure to see a doctor if you experience any of the following:

• Any change in vision (e.g., blurring, loss of clarity)
• If you have difficulty recognizing colors
• If you feel like you're losing your vision

Most importantly: If you suddenly lose your vision or experience severe eye pain, seek medical attention immediately . These could be signs of serious eye conditions.

What are the most important things I should ask the doctor about this?

You will probably have many questions to ask your doctor about this. If possible, bring a friend or family member with you. Make a list of questions you want to ask and bring a notebook to write down your answers. Here are some questions you can ask:

• What is causing my optic atrophy?
• What are my options for treating that cause?
• What are the side effects of those treatments?
• Is this condition hereditary?
• Is it appropriate for my family to undergo genetic testing?
• Are there any clinical trials I can participate in?
• Can you provide information about support groups that help people with this condition?
• What low-vision aids do you recommend that I use?

If you are at risk for optic nerve damage, it is important to see your eye doctor regularly. Optic nerve damage can lead to vision loss, and it can have a major impact on your lifestyle. Remember, your doctors are your best partners in helping you stay healthy. Even though this is a serious condition, there are ways to get the help you need.

So, here are some things to remember from what we've talked about (Take-Home Message):

• Optic atrophy is a serious condition that damages the optic nerve, which carries messages between the eye and the brain, and impairs vision.
• If you experience symptoms such as blurred vision, decreased peripheral vision, or difficulty recognizing colors , don't ignore them.
• There can be a number of reasons for this; decreased blood flow, pressure, inflammation, infection, and accidents are just a few.
• This condition is not contagious , but it can be caused by some infectious diseases.
• There is currently no complete cure for this. Treatment is aimed at the underlying cause, to stop the condition from getting worse.
• It is very important to diagnose the disease early and start treatment. Therefore, get your eyes checked regularly.
• There are devices and services that can help people with visual impairments. Don't give up hope.

It is your responsibility to take care of your eyes, because they are one of the most valuable resources we have for seeing the world.
