Removing the black ring inside the eye: Let's learn more about (Iridodialysis)?

Have you ever noticed that some people have what looks like two black rings in their eyes? Or do you suddenly notice that after a serious eye injury, your vision suddenly changes and you can't even look at the light? One reason why this can happen is a condition called `(Iridodialysis)` that we are going to talk about today. Don't worry, we will talk about this simply and in a way that you can understand.

What is this ``(Iridodialysis)''?

Simply put, `(Iridodialysis)` is the colored part inside our eye, that is , the iris – yes, the one that some of you have that is blue, brown, gray – that is, the part that is attached to the eye, which is detached from the base. It's like a picture that is attached to a wall that has come off on one side.

The base of the iris is connected to the ciliary body . The ciliary body is like a small factory inside the eye . It is the one that produces the aqueous humor , a special fluid that nourishes the eye and maintains its shape. Not only that, but the ciliary muscle that helps the lens of our eyes focus when we look near or far is also located in the ciliary body. So, when the iris is detached from the base of the iris, a condition called `(Iridodialysis)` occurs. This is sometimes called `(coredialysis)`, but there are also cases where it is caused by a different tear during surgery.

Who can develop this `(Iridodialysis)`?

Actually, this condition called ``Iridodialysis'' can happen to anyone, as it is mainly caused by an eye injury .

Think about it:

• If you're playing cricket and a fast-moving ball hits you in the eye .
• What if something – a piece of metal, a pebble – gets thrown into your eye at work and causes an accident?
• If a small child is playing and his eye is hit by something like a table leg.
• What if a friend's elbow hits you in the eye while playing at school?

This can happen. Sometimes, this condition can occur with injuries to the eye during sports, car accidents, falls, especially in older people. It can also happen, although very rarely, during eye surgery , such as cataract surgery .

What are the characteristics of `(Iridodialysis)`?

Now let's look at the symptoms that a person with ``(Iridodialysis)`` may exhibit. Not everyone will experience all of these symptoms, but some of them may be present:

• Double vision (diplopia) : Especially when looking with one eye. Like when the TV antenna is out of order.
• Severe eye pain : Sometimes the pain can be unbearable.
• Bleeding inside the eye (hyphema) : This can causeThe colored part may look like it's filled with blood from the front.
• Change in the size of the pupil : Sometimes, there may be another pupil that appears to be detached. Like a second pupil . This is a major symptom of `(Iridodialysis)`.
• Traumatic cataract: Vision begins to become blurred due to damage to the lens of the eye due to an accident.
• Glare : This means that when you look at lights or sunlight, your eyes become blue and it's hard to look.
• Photophobia : This means that even a small amount of light is difficult for the eyes to tolerate and causes them to close.

If you see a sign like this, you should definitely see a doctor.

Why does this `(Iridodialysis)` occur?

As I mentioned before, the main cause of `(Iridodialysis)` is eye injury . There are two types of these:

1. Blunt eye injury : This means that something hits the eye hard, but the eye is not pierced. For example, a punch, a ball, or a fall that hits the eye somewhere.

2. Penetrating eye injury : This involves a hole in the eye. For example, a knife stab, a wire puncture, or a piece of metal at a work site that suddenly enters the eye.

For example, if you hit your face on the front seat or steering wheel in a car accident, or if you get something in your eye while working without safety glasses (e.g., in a woodworking shop or metalworking shop), there is a high chance that you will develop `(iridodialysis)` with such severe injuries. We call `(iridodialysis)` caused by an accident like this traumatic iridodialysis .

Sometimes, very rarely, this can also occur as a complication of eye surgery.

How does a doctor detect this?

If you have had an eye injury and have the symptoms I mentioned earlier, you should see an eye care provider/ophthalmologist immediately. When a doctor examines your eye, they can check to see if the iris has detached. They use special equipment to do this.

In addition, the following tests can be performed to check for other damage to the eye or foreign bodies:

• Ultrasound of your eye : This allows you to see the delicate parts inside your eye.
• CT scan (computed tomography scan) : This can be used to see if there is any damage to the bones around the eye or if there are any small fragments inside the eye.

The doctor will also perform a test called gonioscopy . This is a painless test. It checks whether the aqueous humor in the eye is draining properly.Is there a possibility of a condition like glaucoma ?

What are the treatments for `(Iridodialysis)`?

The best part is, not all iridodialysis cases require treatment. Sometimes, if the iris detachment is small and there are no major symptoms (e.g., vision is good, no pain), your doctor may just tell you to wait it out. Your eye can adjust to it over time.

In some cases, special contact lenses can be used to reduce the appearance of a second black ring and reduce sensitivity to light. These lenses can be tinted to match the color of the iris and cover the missing area.

However, if the iris is too large, you may also:

• If you see two things with one eye, you have ``double vision in one eye'' .
• If you can't stand the glare .
• If you are very sensitive to the outdoors (photophobia) .
• If you are uncomfortable with your appearance (due to eye differences, some people find this very uncomfortable).

...In cases like this , surgery may be necessary.

Surgery for `(Iridodialysis)`

There are various surgical procedures to reattach the iris. Doctors try to preserve the natural appearance and function of the eye as much as possible.

• Sometimes, the detached iris is reattached to the root using very fine special stitches (sutures) .
• In some cases, attempts are made to fix this using laser technology.
• A new procedure is the implantation of an artificial iris along with an intraocular lens (IOL ) . This is done when the iris has been severely damaged.

However, most of the time, after an eye accident, this `(Iridodialysis)` treatment is only performed until the eye has healed a little and the swelling has subsided. Because it is not always good to perform surgery immediately after the injury.

This intraocular lens is a clear artificial lens that works like the natural lens in our eye . When light enters the eye, it passes through this lens and hits the retina . These artificial lenses are used to remove cataracts and insert them, as well as in some iridodialysis surgeries.

Can't you survive `(Iridodialysis)`?

It is not possible to completely prevent `(Iridodialysis)`. Because the risks are not what we expect. However, by protecting your eyes, this risk can be greatly reduced. According to the data we have, about 90% of eye injuries can be prevented . Here are some things you can do:

• Always wear protective eyewear when you work, especially when cutting, grinding, welding, or working with chemicals. Don't wait until later to "put it on."
• When playing fast-paced sports, for example cricket (especially when fielding and batting), squash, or cycling, be sure to wear safety glasses or a helmet appropriate for that sport.
• Always wear your seatbelt when driving. This will greatly reduce the risk of injuries to your head and face.
• Be careful when doing household chores. For example, think about your eyes when cutting branches in the garden or driving a nail.

When should I see a doctor?

This is very important. If you have any kind of eye trauma or injury , don't just sit there thinking, "This is just a small thing." Sometimes, even if the damage you see on the outside is minor, there may be significant damage inside the eye. Therefore, be sure to see a doctor, preferably an ophthalmologist.

Then you can ask the doctor questions like:

• "Doctor, how long will it take for me to get better?"
• "When can I resume my normal activities (work, schoolwork)?"
• "What symptoms should I see you immediately or go to the emergency room if I develop?" (e.g., sudden loss of vision, unbearable pain).
• "What should I do to prevent something like this from happening again?"
• "How do I schedule my next check-up?"

Don't be afraid to ask these questions. Your eyes are very valuable to you.

What is the difference between `(Cyclodialysis)` and `(Iridodialysis)`?

These two names are somewhat similar, which can lead to confusion. Although they are both eye conditions, there is a slight difference.

• Iridodialysis is the removal of the iris , the colored part of the eye , from its original location.
• But cyclodialysis is the process of separating the ciliary body (the part of the eye that makes the fluid that nourishes the eye and attaches to the iris) from the white part of the eye ( the sclera ).

When the ciliary body detaches from the sclera, the flow of the aqueous humor inside the eye is obstructed, causing it to accumulate inside the eye, increasing eye pressure and causing a condition called glaucoma .

What is the difference between `(Iridonesis)` and `(Iridodialysis)`?

These two names are a bit similar, so they can be confused. Both are related to the iris, the colored part of the eye .

• Iridodialysis is the removal of the iris.
• But Iridonesis is when the iris twitches when you move your eyes from side to side.. Like jelly. Here the iris does not move, but it does not move steadily and shows a shaking appearance. This can sometimes be due to an injury to the eye or a problem with the lens of the eye .

Finally, things to remember

So, `(Iridodialysis)` is a dangerous condition that occurs when the iris, the colored part of the eye , is detached from its original position. This can sometimes cause the eye to appear as a second black ring, make it difficult to see in the light, and can be painful.

The most important thing is that if you have any kind of eye injury, even if you think it's minor, or if you notice anything unusual after eye surgery (e.g., vision changes, pain, inability to see light, redness of the eye), see an ophthalmologist immediately without delay.

If you detect the disease early and get the necessary treatment, you can achieve good results. In many cases, you can even save your vision. Therefore, it is your responsibility to take care of your eyes. Because we only have these two eyes to see this beautiful world!
