Is your vision blurry and streaky? It could be a macular hole!

Do you suddenly feel that straight objects, such as window frames and door frames, are stretched and wrinkled? Or do you feel that when you read a newspaper or a book, the letters are blurry and there is a black spot or blank space right in the middle of where you are looking? If you have experienced something like this, don't just dismiss it as normal. This could be due to a hole in the part of your eye that is very sensitive and essential for vision, called the 'macula'. Don't worry, we will talk about everything in a simple way that you can understand.

What exactly is a macular hole?

To understand this, let's first take a look at how our eyes work. Our eyes are like high-tech cameras. The part of the eye that acts like the film behind the camera, converting light into nerve signals and sending them to the brain, is called the retina .

So, right in the center of this retina, there's a very important little spot that gives us clear, sharp vision. It's this little spot that helps us do things like read a book, recognize a face, and drive a car. That's what we call the macula .

Now let's look at how the hole forms. The inside of our eyes is filled with a jelly-like substance, similar to egg white. This is called the vitreous humor in medical terms. As we age, this jelly gradually turns into water and begins to shrink. It's like a grape drying up and becoming a raisin. As it shrinks, it pulls away from the back wall of the eye, the retina. This is normal.

But sometimes, this jelly can stick a little too tightly to the sensitive area we mentioned, the macula. Then, as the jelly shrinks and comes off, it pulls the macula along with it. Just like a poster stuck to a wall suddenly comes off with some of the plaster on the wall, a small hole can form in the macula. That's what we call a macular hole. This usually happens in one eye, but very rarely, it can happen in both eyes.

How common is this condition? Are there any types?

Actually, this is not a very common condition that affects everyone. But it can happen to anyone. Studies have shown that people over the age of 55 are especially at risk. And, surprisingly, this condition is more common in women than in men.

Doctors divide this condition into two main types:

1. Primary macular holes: These are the most common. They occur without any other disease or injury, and are caused by the changes inside the eye that occur with aging, as we discussed earlier.

2. Secondary macular holes: These are caused by another cause. For example, a severe eye injury, an infection inside the eye (uveitis) , or a complication after cataract surgery can cause this type of hole.

Also, doctors divide this hole into several stages depending on the severity. Your doctor will perform special tests and clearly tell you which stage your condition is in and how serious it is.

What are the symptoms of this? Let's find out exactly.

These symptoms do not come on suddenly. They develop gradually. It is very important to recognize them early.

Why does this happen? What are the risk factors?

As we discussed earlier, the main cause is that as we age, the jelly inside the eye (vitreous humor) shrinks and pulls away from the macula. However, this doesn't happen to everyone. Some people are at higher risk.

Factors that increase this risk are:

• Age: Being over 55 years of age is a major factor.
• Gender: Women are at higher risk.
• Eye injuries: If you have previously suffered a severe blow to the eye.
• High Myopia: This risk is higher for people who wear very thick glasses and cannot see far.
• Other eye surgeries: Rarely, it can occur after things like cataract surgery.
• Infections inside the eye: Conditions such as uveitis.
• Retinal Detachment: If the retina has previously detached.

How do you find this, Doctor?

When you go to the doctor, he will first ask you about your symptoms, the medications you take, and whether anyone in your family has eye problems. Then he will do a complete eye exam.

In this, your eye will be dilated with eye drops, and the inside of your eye will be examined with a special instrument (slit lamp) . This allows the retina and macula to be seen clearly.

Special tests

After a general examination, the doctor may perform several more special tests to confirm the condition of the patient and determine the exact size and stage of the hole.

• Optical Coherence Tomography (OCT): This is the most important test. It's like taking a 3D scan of the inside of the eye. It takes a cross-sectional image of the retina and macula. It helps to see exactly how big the hole is, how deep it is, and whether there is any damage to the surrounding tissue. It's a painless test that can be done in a few minutes.
• Fundus Fluorescein Angiography: In this, a special dye is injected into a vein in your arm and pictures are taken of the blood vessels inside the eye. This helps to check for other problems inside the eye.
• Fundus Photography: This is a color photograph of the inside of the eye, the retina. It is used to compare the condition before and after treatment.

What are the treatments for this?

After diagnosing this condition, the doctor will determine the most appropriate treatment for you.

• Observation: Sometimes, if the hole is very small, that is, in the first stage, it may close on its own. In such cases, the doctor will observe you for a while without performing surgery.
• Vitrectomy surgery: This is the main and most successful treatment for this. This surgery is successful in more than 90% of cases.

What is Vitrectomy surgery?

This is a procedure performed by an eye surgeon who specializes in retina surgery. Simply put, this involves:

1. The doctor completely removes the vitreous gel inside the eye. This jelly is what pulled on the macula and caused the hole.

2. Then, if there are any thin membranes that are causing traction on the macula, they are also very carefully removed.

3. Finally, a special gas bubble is placed inside the eye to help the hole close. This gas bubble applies pressure to the hole, forcing the edges of the hole together, much like plaster is being applied to a hole in a wall.

What should I be careful about after surgery?

For the surgery to be successful, it is essential that you follow the doctor's instructions carefully after the surgery.

Possible complications after surgery

As with any surgery, complications can occur very rarely.

• Retinal detachment
• Having an eye infection
• Increased eye pressure (Glaucoma)
• Bleeding inside the eye
• The hole reopens or does not close at all
• Cataracts: This is more of a complication than a side effect, and is something that almost everyone who has undergone retinal surgery will experience. Therefore, your doctor will inform you about it in advance.

What to know during recovery

• Appearance: Your vision will be blurry for the duration of the gas bubble in your eye, which is about 3-8 weeks. Don't worry about that. Your vision will gradually clear up as the gas bubble is absorbed into your body. It may take several months for your vision to fully stabilize.
• Driving and flying: This is very important! Do not drive or fly for any reason while you have a gas bubble in your eye. Changes in air pressure (such as on a plane or in a mountainous area) can cause the gas bubble inside your eye to expand, causing dangerously high pressure inside your eye, which can cause permanent damage to your eye. Follow these restrictions until the gas bubble is completely gone. Your doctor will tell you exactly when to do so.

Will my sight be restored? Can't this be prevented?

This is the biggest question many people have: "Will I ever look the same again?"

The good news is that surgery is more than 90% successful. The sooner you treat the hole, the better the outcome. You can regain most or some of your lost vision. However, your vision may not be 100% the same as it was before. However, many people can improve their vision to the point where they can do things like read and drive again.

Can this be prevented?

In fact, there is no way to completely prevent this age-related condition. However, you can protect yourself to some extent by maintaining good eye health and reducing your risk.

• Wear protective eyewear when playing sports or doing hazardous work.
• Get regular eye exams . At least every two years. While this cannot prevent the disease, it can detect it in its early stages.
• If you have diabetes or hypertension , control them well, as these conditions directly affect eye health.

When should I see a doctor?

It's important for everyone to have regular eye exams. In addition, if you notice any changes in your vision, especially blurred vision, don't ignore it. See a doctor right away without delay.

Questions to ask the doctor

When you find out that you have this condition, you may have many questions in your mind. Don't be afraid or hesitant to ask your doctor about these things.

• What kind of treatment is recommended for me? Do I need surgery?
• What are the side effects or complications of this treatment?
• Could this situation happen again?
• What should I do to protect my eyesight?
• Will I be able to drive again after treatment?

The eyes are one of the most precious and sensitive organs in our body. So it's normal to feel scared when you have an eye problem. But remember, there are now very effective treatments for a condition called macular hole. The most important thing is to diagnose the disease early and seek the right treatment.
