A conjunctival cyst is a fluid-filled sac that forms on the outer layer of your eye, the conjunctiva. It can form for a variety of reasons, including ongoing inflammation, trauma, or surgery on the eye.
One of the ways to get rid of a conjunctival cyst is to drain it. (Learn More) Typically, to keep the cyst from coming back, the cyst will need to be removed completely through a surgical procedure. (Learn More)
Surgery is usually a minor outpatient procedure that is often done with the assistance of a laser. Laser surgery is fast, effective, minimally invasive, and a safe way to remove a conjunctival cyst completely. (Learn More)
Conjunctival cysts will often go away on their own. Your doctor can determine if you need a surgical intervention or if there are techniques that can help you cope while the cyst clears up on its own. (Learn More)
Since a cyst is a sac that is filled with fluid, it can be drained through a procedure called aspiration. This procedure is typically a same-day intervention that uses topical anesthetic.
A needle is used to drain the cyst, and this can be an effective way to get rid of a small conjunctival cyst. There are often no reported complications, and this can be enough to keep the cyst from returning.
When cysts are bigger, a surgical option is usually recommended.
In order to completely remove a conjunctival cyst and keep it from coming back, surgery that completely and carefully removes the cyst intact is often recommended.
There are several surgical methods that can safely and completely remove a conjunctival cyst.
- Surgical excision, often using staining dye: Complete removal of a conjunctival cyst through traditional surgical means will often use a dye to stain the tissue. This allows the surgeon to see all the margins of the cyst so they can remove it all at once and in one piece. This option is considered effective and simple.
- Injection of a sclerosing agent with aspiration: Along with aspiration, sclerotherapy can be used as a minimally invasive surgical procedure to completely remove a conjunctival cyst. Reports show no ocular complications or significant swelling; therefore, this procedure is considered safe and effective.
- Laser-assisted excision: Several different types of lasers have been used to help excise conjunctival cysts. Lasers are often less invasive and more precise than traditional surgical tools.The YAG laser can be used to rupture the cyst, while the argon laser is used for photoablation. Both of these options can generate a lot of heat. This can cause damage to healthy tissues.Today, the pattern scan laser (PASCAL) is often used instead, as it does not require contact for as long of a time. This laser can be used in an office setting, and it is less invasive. Patients often experience less pain due to less time needed to pulse the laser.Overall, the PASCAL laser-assisted procedure has been proven to be effective and safe in the removal of conjunctival cysts.
- Atmospheric low-temperature plasma (ALTP): A relatively new procedure that can be even safer and less invasive than laser-assisted surgical removal of a conjunctival cyst is one that uses plasma spots. The plasma-based approach uses an atmospheric low-temperature plasma (ALTP) directly on the cyst to remove the fluid.Then, the ALTP is applied to areas around the cyst, which can help ensure that the cyst will not come back. This is important as cyst recurrence is one of the main complications of surgical removal. This often occurs because not all of the cyst was removed.Studies published in the journal Clinical Ophthalmology report that the ALTP approach can be less expensive, more effective, simple, office-based, and a minimally invasive way of safely removing a conjunctival cyst.
Management of a Cyst Without Surgical Intervention
Often, a conjunctival cyst will not need treatment or a surgical intervention. It can clear up completely on its own.
Conjunctival cysts are usually small and may not cause any symptoms. When this is the case, a doctor will often recommend using some coping methods to manage the cyst. This allows you to live with it temporarily to see if it will clear up without a more invasive treatment.
Lubricating eye drops like artificial tears can help if you are experiencing irritation or dry eyes. Your doctor can also prescribe short-term steroid eye drops to manage inflammation and keep the cyst from getting any bigger. Cold compresses can help with discomfort as well.
The type, severity, and cause of your conjunctival cyst will play a role in what is the best treatment option for you. A conjunctival cyst can make it feel like you have something in your eye and also make it difficult to open and close your eyelid.
When a conjunctival cyst is impairing your quality of life, it is time to seek out a medical intervention. Surgery for removing a conjunctival cyst is generally minor and minimally invasive, performed as a same-day in-office procedure.
Talk with your doctor about your situation, so you can determine the best and safest way to manage or remove your conjunctival cyst.
