Conjunctival Cyst: Symptoms, Causes, Treatment

What are the symptoms of a conjunctival cyst?

A conjunctival cyst is a small, fluid-filled sac that forms on the conjunctiva, the clear membrane that covers the white part of the eyeball and lines the inside of the eyelids. The symptoms of a conjunctival cyst can vary depending on its size and location, but common symptoms may include:

1. A painless lump or bump on the conjunctiva.
2. A sensation of something in the eye.
3. Redness and irritation.
4. Excessive tearing.
5. Blurred or distorted vision if the cyst is large or pressing on the cornea.

Conjunctival cysts are usually harmless and may resolve on their own without treatment. However, if a cyst is causing discomfort or affecting vision, it may need to be removed surgically. If you suspect you have a conjunctival cyst or are experiencing persistent eye symptoms, it’s important to see an eye care professional for an accurate diagnosis and appropriate treatment.

What are the causes of a conjunctival cyst?

Conjunctival cysts can have several causes, including:

1. Blocked Glands: The most common cause of conjunctival cysts is a blocked or obstructed gland in the conjunctiva. These glands produce mucus and help lubricate the eye. When one of these glands becomes blocked, the mucus can accumulate and form a cyst.
2. Trauma: Physical injury to the eye or the conjunctiva can lead to the formation of a cyst as the body’s response to the injury.
3. Inflammation: Chronic inflammation of the conjunctiva, known as chronic conjunctivitis, can sometimes result in the formation of cysts.
4. Infection: In rare cases, bacterial or viral infections of the conjunctiva can lead to the formation of cysts.
5. Foreign Bodies: Sometimes, a foreign body that becomes trapped under the conjunctiva can lead to the formation of a cyst as the body tries to isolate and encapsulate the foreign material.
6. Contact Lens Use: Extended wear or improper care of contact lenses can sometimes lead to irritation of the conjunctiva and the formation of cysts.

Conjunctival cysts are usually benign and do not cause serious problems. However, if a cyst is causing discomfort or affecting vision, it may need to be removed surgically. It’s important to see an eye care professional for an accurate diagnosis and appropriate treatment if you suspect you have a conjunctival cyst.

What is the treatment for a conjunctival cyst?

The treatment for a conjunctival cyst depends on the size and severity of the cyst and whether it is causing symptoms. In many cases, small conjunctival cysts that are not causing any symptoms may not require treatment and may resolve on their own over time.

If the cyst is causing discomfort, redness, or vision problems, or if it is large and persistent, treatment options may include:

1. Observation: Sometimes, a small cyst may be monitored to see if it resolves on its own without treatment.
2. Warm Compresses: Applying a warm compress to the affected eye several times a day may help reduce swelling and promote drainage of the cyst.
3. Steroid Eye Drops: In some cases, steroid eye drops may be prescribed to reduce inflammation and promote the resolution of the cyst.
4. Surgical Removal: If the cyst is large, persistent, or causing significant symptoms, it may need to be surgically removed. This procedure is typically performed by an eye care professional and is usually done using local anesthesia.
5. Cauterization: In some cases, a procedure called cauterization may be used to remove the cyst. During cauterization, a small instrument is used to apply heat or a chemical to the cyst, causing it to shrink and eventually disappear.

It’s important to see an eye care professional for an accurate diagnosis and appropriate treatment if you suspect you have a conjunctival cyst or are experiencing persistent eye symptoms.
