A conjunctival cyst is a small, fluid-filled sac on the conjunctiva, the thin tissue covering the white part of the eye and the inside of the eyelids. These cysts are typically harmless and may not cause any issues. Many people are unaware they have a conjunctival cyst because it often shows no symptoms. When it does cause discomfort, it can feel like a bump on the eye or eyelid. Sometimes, it may cause irritation or a scratchy sensation. These cysts usually do not affect vision, but they might obstruct the view if they grow larger. If a conjunctival cyst becomes troublesome, a doctor may suggest treatment, such as draining the cyst or removing it completely. It is important to consult a healthcare professional if you notice any changes in your eye or ongoing discomfort. Regular eye check-ups can help detect issues early. Overall, conjunctival cysts are usually not a concern, but staying informed is beneficial.
Common signs and symptoms of conjunctival cysts include:
Small, round bump: A translucent or yellowish cyst on the surface of the eye or eyelid.
Discomfort: Mild irritation or a sensation of something in the eye.
Redness: The surrounding area may be slightly red or inflamed.
Tearing: Increased tear production may occur.
Vision changes: In rare cases, a large cyst may obstruct vision.
Conjunctival cysts can form due to various causes, including:
Blocked glands: Obstruction of glands that produce tears can lead to cyst development.
Infections: Past eye infections may result in cyst formation.
Allergic reactions: Allergies can cause inflammation, leading to cysts.
Irritation: Frequent eye rubbing or exposure to irritants can trigger cyst formation.
Consult a doctor if you experience:
Persistent cyst: A cyst that doesn't go away after a few weeks.
Increasing discomfort: If the cyst becomes painful or bothersome.
Vision changes: Any significant changes or disturbances in your vision.
Signs of infection: Redness, swelling, discharge, or worsening symptoms.
Certain factors may increase the likelihood of developing conjunctival cysts: Past eye injuries can lead to cyst formation. Chronic eye conditions such as dry eye syndrome or blepharitis may increase the risk. Allergies, especially allergic conjunctivitis, might make individuals more susceptible to cysts. Older adults could be more vulnerable due to changes in the eye's surface.
To diagnose a conjunctival cyst, an eye doctor may perform:
Eye examination: A thorough examination of the eye using a slit lamp to view the cyst and surrounding tissues.
Medical history review: Discuss symptoms and any history of eye conditions or allergies.
Vision tests: Assessing visual acuity to ensure the cyst isn't affecting vision.
Do's:
Keep the area clean: Gently clean the eyelid area with mild soap and water.
Use warm compresses: Apply them to soothe irritation and promote drainage.
Follow doctor's advice: Adhere to any prescribed treatments or medications.
Stay hydrated: Drink plenty of water to support overall eye health.
Don'ts:
Don't rub your eyes: This can irritate the cyst and worsen symptoms.
Avoid wearing contact lenses until the cyst resolves to prevent irritation.
Don't self-treat: Avoid popping or draining the cyst on your own.
Avoid irritants: Stay away from smoke, dust, or other allergens that may worsen symptoms.
