Have you ever thought about how amazing our eyes are? Our eyes work like a camera. A very sensitive and important part of the eye is the retina. Sometimes this retina can become detached. That's why we call it retinal detachment, or `(Retinal Detachment)`. This is a very serious condition, although it is painless. Let's talk about this in detail today, because being aware of this is very important for you and your loved ones.
What is the retina? What does it mean to detach?
Simply put, the retina is a light-sensitive membrane at the back of your eye. It's like the film in a film camera. When light from the things you see falls on the retina, it creates electrical signals that travel to your brain. That's when you see.
Now think about it, what happens if this retina separates from the tissues that nourish it and hold it in place? That's what's called a retinal detachment. When it separates like this, the retina loses its blood supply, oxygen, and nutrients. This can damage your vision and, if left untreated, can lead to blindness. So this is not something to be taken lightly.
Most importantly, this condition is usually painless, so it is important to seek medical advice as soon as symptoms appear.
What are the symptoms of retinal detachment? What to do if you experience these symptoms?
Some people may not experience any symptoms at all. However, most people develop some symptoms suddenly. The severity of these symptoms can vary depending on how much of the retina is detached.
Be very careful about these signs:
- Seeing a lot of things floating in front of your eyes all at once: Small dots, pieces of string, net-like objects, and black spots may appear to float by when you move your eyes. It's normal to see one or two every now and then, but you should be concerned if you start seeing a lot of them all at once.
- Photopsia: Seeing lights as if they were suddenly flashing inside the eye.
- Feeling like your vision is going dark: Your peripheral vision may feel dark, as if a black curtain has been placed on the side.
- Feeling like a black curtain is covering part of your vision: Like a curtain falling on a window, one side of your vision may gradually become dark.
If any of these symptoms appear, you should see an ophthalmologist or go to an emergency room as soon as possible, without waiting for the pain to subside. Doctors want to start treatment as soon as possible.
What are the main types of retinal detachment?
There are three main ways in which a retina can detach:
1. Rhegmatogenous type: This is the most common type. It usually occurs as people get older. The gel-like substance inside the eye (called the `vitreous humor`) shrinks, thins, and pulls away from the retina as they age. At this point, a small hole (`retinal tear`) can form in the retina. Through that hole, the gel-like fluid collects behind the retina, pushing the retina away.
2. Tractional type: In this type, the retina is pulled and detached due to scar tissue that forms on the retina. People with diabetes (`Diabetes Mellitus`) are more likely to have this type of detachment. This is because when blood sugar levels are high for a long time, scar tissue can form due to damage to the blood vessels in the eye. As these scars grow larger, they pull and detach the retina.
3. Exudative type: In this type, fluid builds up behind the retina without a hole in the retina. The main causes of fluid build-up are fluid leaking from blood vessels inside the eye or swelling behind the eye. This can happen due to certain inflammatory conditions of the eye (uveitis).
How common is retinal detachment?
This is not a disease that affects everyone. According to American data, it is said that about one in ten thousand people can develop it per year. Another study says that the most common type, rhegmatogenous lupus, can develop in a rate of between 6 and 18 per hundred thousand. This means that although it is not very common, it is important to remember that anyone can develop it.
What are the causes and risk factors for retinal detachment?
There are several causes and risk factors that contribute to this:
- Aging: People over 50 years of age are at higher risk.
- Eye injury: If the eye receives a sharp blow, such as in an accident.
- If you have previously had a detached retina or if someone in your family has this condition.
- If you have had previous eye surgery: for example, after cataract surgery.
- People with poor farsightedness (very nearsighted): For those with very high prescription glasses.
- Posterior Vitreous Detachment: The gel-like substance inside the eye separates from the retina.
- Other conditions that affect the retina: For example, thinning of the retina (lattice degeneration) or diabetes-related retinopathy.
- Some hereditary eye diseases.
- If one eye has a hole or detachment in the retina, the other eye is also at risk.
If you have these risk factors, it is very important to talk to your doctor and have your eyes checked at regular intervals.
What are the complications of this condition?
Retinal detachment is a serious condition. It can lead to vision loss. In fact, if left untreated, it can lead to permanent blindness within a few days. That's why it's important to seek treatment as soon as symptoms appear.
How do doctors find this?
To find this out, you need to have a dilated eye exam . Your eye doctor will dilate your eye with eye drops to examine your retina. After a few minutes, the doctor will be able to see your retina clearly.
After this examination, your doctor may recommend some other painless tests. These can provide a clearer, more detailed view of your retina:
- Optical Coherence Tomography (OCT): This is also a magnified scan of the eye. You sit in front of a machine, hold your head still, and the machine scans your eye. Nothing hits the eye.
- Fundus imaging: This also takes pictures of the retina. The eye is usually dilated for this.
- Eye (ocular) ultrasound: This does not require dilating the eye. However, eye drops may be used to numb the eye. While you are sitting in a chair and your head is still, a small device is placed over your eye and scanned. Next, while your eyes are closed, a gel is placed over your eyelids, and the device is used to move your eyes around.
- CT Scan (`Computed Tomography - CT scan`): This is a test that combines `X-rays` and a computer. It is usually done when there is an injury to the eye and there is a suspicion that something has gotten inside.
How is retinal detachment treated?
Your eye doctor will talk to you about the treatment options that are right for you. Sometimes, more than one treatment option may be used to achieve the best results.
The main treatment methods are:
- Laser therapy or cryopexy (freezing therapy).
- Pneumatic retinopexy (air bubble therapy).
- Scleral buckle (silicone strapping).
- Vitrectomy (surgery to remove the vitreous).
Laser treatment or cryopexy
Sometimes, before the retina detaches, the doctor can find just a hole in the retina (a `retinal tear`). Then, the doctor uses a medical laser or a freezing device to close the hole. This creates a scar and helps the retina stay in place.
Pneumatic retinopexy (air bubble therapy)
What happens in this case is that the doctor injects a small air bubble into the eye. The bubble sticks to the retina, closing the hole. The hole can then be permanently closed using a laser or cryopexy. The fluid that has accumulated under the retina is then absorbed into the body. The retina can then reattach to the wall of the eye. After a few days, the air bubble is also absorbed into the body.
After this surgery, it's very important to keep your head still and sleep as the doctor says. Although it's a little uncomfortable, it's a short-term sacrifice for a long-term benefit.
Scleral buckle (silicone strapping)
In this procedure, the doctor surgically attaches a silicone band or sponge (a `buckle`) around the eye. This band helps hold the retina in place. The band is permanently there, but you can't see it. Then, the hole is closed using a laser or cryopexy. Sometimes, an air bubble may be punctured or fluid may be removed from under the retina to help the retina reattach.
Vitrectomy (surgery to remove vitreous)
Here are the things that are done during a vitrectomy:
- The gel-like substance inside the eye (the `vitreous`) is surgically removed.
- Any holes in the retina are closed using either a laser or a freezing method.
- A bubble of air, gas, or oil is placed inside the eye to push the retina back into place.
If the doctor inserts an oil bubble, it will be removed surgically in a few months. The air and gas bubbles are absorbed by the body. If you have an air bubble inserted into your eye, you will need to stop traveling to high places and flying for a while. This is because the size of the air bubble and the pressure inside the eye (intraocular pressure) can increase as the altitude changes. Your doctor will tell you when you can do these things again.
Are there any complications or side effects of the treatment?
Retinal detachment surgery is generally very successful. However, as with any surgery, there are some risks and complications:
- Bleeding.
- Infection.
- Increased pressure inside the eye.
- Possibility of having to have another surgery.
- After surgery, membranes may form, which can shrink and pull on the tissue. This is called ``Proliferative Retinopathy`` or ``Epiretinal membrane``.
- He quickly developed a cataract, which required surgery.
What can you expect after retinal detachment surgery?
After treatment, you may feel some discomfort for a few weeks. Your doctor will tell you about painkillers and other ways to help you. You should also avoid strenuous activity for a few weeks. Talk to your doctor about when you can resume exercising, driving, and other normal activities.
Other things to expect after surgery:
- Eye patch: Keep the eye patch on until your doctor tells you to.
- How to hold your head: If you have a blister in your eye, follow the instructions exactly on how to hold your head. Your doctor will tell you how to hold your head and how long to hold it to help your eye heal.
- Eye drops: The doctor will give you instructions on how to use eye drops to help your eyes heal.
- Vision improvement: You should notice your vision gradually improving within four to six weeks after surgery. It may take several months to see full results.
Can retinal detachment be prevented?
The most common type, called rhegmatogenous, is not completely preventable. But there are things you can do to reduce your risk:
- Get regular eye exams: Getting your eyes checked regularly can help protect your eye health. It's especially important to get your eyes checked if you have nearsightedness (myopia), as myopia increases your risk of developing a retinal detachment. Your eye doctor can perform a dilated exam to check for small holes in your retina.
- Stay safe: Use eye protection such as safety goggles when playing sports or doing risky work.
- Seek immediate treatment: If you experience symptoms of retinal detachment, see an ophthalmologist or go to an emergency room immediately.
- Maintain your overall health: manage chronic diseases, eat a balanced diet, and exercise regularly.
To prevent tractional glaucoma caused by diabetes mellitus, it helps to control your blood sugar levels and blood pressure well.
How often should you have your eyes checked?
It is generally a good idea to have your eyes checked once a year for people who are at low risk of developing eye disease. If you are at high risk of developing eye disease, you may need to have your eyes checked more often. Talk to your doctor about the best screening schedule for you.
What happens if I get a retinal detachment?
Your situation will depend on factors such as what your vision was like before the retinal detachment, how far the detachment has progressed, and whether there are any other complications. Your doctor will talk to you about what kind of vision you can expect to regain.
Surgery for rhegmatogenous retinal detachment is usually very successful - nine out of ten people recover. Sometimes more than one operation is needed to reattach the retina.
Can the retina come back?
Yes, it is possible for a retinal detachment to occur more than once. If this happens, a second surgery may be necessary. Talk to your doctor about preventive measures you can take to protect your vision.
How do I take care of myself?
The most important thing is to follow your eye doctor's instructions exactly, especially regarding head position and your activities.
Ask your doctor about ways to make things easier, such as using a firm neck pillow to help keep your head in one position. If you have to lie face-down, your doctor's office can help you get face-down equipment to use at home.
When should I go to the emergency room?
Your surgeon's instructions will list what emergencies are, but you should call your doctor or seek emergency treatment immediately if any of the following occur:
- If severe, unexpected pain occurs.
- If you develop signs of infection (e.g. swelling, fever).
- If there is an unexpected discharge coming from the ear.
- If you suddenly lose your vision.
What questions should I ask my eye doctor?
If you have a detached retina (or are at high risk for it), ask your doctor about the following:
- What is the best treatment for cataracts for me?
- Do I need surgery?
- How can I protect the health of my eyes after surgery?
- How often should I have my eyes checked?
- What else can I do to reduce the risk of retinal detachment?
Final Take-Home Message
Retinal detachment is a painless but serious condition. If you suddenly start seeing floaters, flashes of light, or blurred vision, seek medical attention immediately. See an eye doctor or go to the emergency room. A retinal detachment requires some type of surgery to repair. Even if treatment is delayed for a few days, permanent vision loss can occur. After surgery, it is important to follow your surgeon's instructions to protect your vision.
