Definition:
A conjunctival cyst is a small, fluid-filled sac that develops on the conjunctiva, which is the clear, thin membrane that covers the outer surface of the eye and lines the inside of the eyelids.
Causes:
Conjunctival cysts can occur due to various reasons, including:
- Obstruction: Blockage of the tear ducts or the mucus-secreting glands in the conjunctiva can lead to the formation of cysts.
- Infection: Bacterial or viral infections of the conjunctiva may cause the development of cysts.
- Inflammation: Chronic inflammation or irritation of the conjunctiva can result in cyst formation.
- Trauma: Injury or trauma to the eye can cause the conjunctiva to develop cysts as a part of the healing process.
Symptoms:
Common symptoms associated with conjunctival cysts include:
- Eye Irritation: The presence of a cyst can cause discomfort, itching, and a gritty sensation in the eye.
- Redness: The affected area may appear reddened or bloodshot.
- Blurry Vision: Large cysts or those located near the visual axis can temporarily blur vision.
- Tearing: Excessive tearing or watery eyes can occur.
Treatment:
Depending on the size and severity of the conjunctival cyst, treatment options may include:
- Observation: Small, non-bothersome cysts may be monitored without intervention.
- Conservative Measures: Warm compresses or artificial tears can help soothe the discomfort associated with the cyst.
- Surgical Intervention: Large or persistent cysts may require surgical removal by an ophthalmologist.
- Medication: In certain cases, antibiotic or anti-inflammatory eye drops or ointments may be prescribed to reduce swelling and prevent infection.
