What are Eyeball Cysts?

A cyst on the eyeball, or more accurately, on the surface of the eye or surrounding structures, is a fluid-filled sac that can develop in various locations. These aren't necessarily harmful, but some can affect vision or cause discomfort. It's crucial to have any eye abnormality examined by an ophthalmologist.

Types of Eye Cysts

Several types of cysts can affect the eye and its surrounding structures:

Meibomian Gland Cysts (Chalazia): These are the most common type, stemming from blocked oil glands in the eyelids. While not technically on the eyeball itself, they can significantly impact the eye's appearance and comfort. They often appear as painless bumps on the eyelid.
Episcleral Cysts: These cysts develop in the episclera, the thin layer of tissue between the sclera (white of the eye) and the conjunctiva (the membrane covering the white of the eye). They might appear as small, clear bumps on the white of the eye.
Conjunctival Cysts: Located in the conjunctiva, these cysts can be relatively harmless and often go unnoticed unless they become large enough to affect vision.
Intraocular Cysts: These cysts form within the eye itself. They are less common and often associated with underlying medical conditions.

Causes of Eyeball Cysts

The cause of an eye cyst varies depending on the type:

Meibomian Gland Cysts: Blockage of the meibomian glands, often due to inflammation or infection (blepharitis).
Episcleral and Conjunctival Cysts: The exact cause isn't always clear, but they can sometimes be related to inflammation or minor trauma.
Intraocular Cysts: These cysts can be linked to various conditions, including tumors, retinal detachments, or developmental abnormalities.

Symptoms of Eyeball Cysts

Symptoms vary widely depending on the cyst's type, size, and location:

Meibomian Gland Cysts: Usually painless but can cause redness, swelling, and slight discomfort. Vision is typically unaffected.
Episcleral and Conjunctival Cysts: Often appear as small bumps, possibly slightly raised and clear or yellowish in color. They may not cause any symptoms unless they become large enough to affect vision or irritate the eye.
Intraocular Cysts: Symptoms depend on the cyst's location and size. They might cause blurred vision, floaters, or other visual disturbances.

Diagnosing Eye Cysts

An ophthalmologist can diagnose an eye cyst through a thorough eye exam. This may include:

Visual Acuity Test: To assess vision.
Slit-Lamp Examination: To closely examine the eye's structures.
Imaging Tests: Such as ultrasound or MRI, might be necessary for intraocular cysts.

Treatment for Eyeball Cysts

Treatment options depend on the cyst type and its impact on vision or comfort:

Meibomian Gland Cysts: Often resolve on their own. Warm compresses can help drain the cyst. In some cases, surgical removal or injection of corticosteroids may be necessary.
Episcleral and Conjunctival Cysts: Often require no treatment unless they cause discomfort or affect vision. Surgical removal may be considered in such instances.
Intraocular Cysts: Treatment depends on the underlying cause and may involve surgery, medication, or other interventions.

When to See a Doctor

Seek immediate medical attention if you experience:

Sudden vision changes.
Severe eye pain.
Redness and swelling around the eye.
A rapidly growing cyst.
