What Is Conjunctival Cyst?

Q:
What is conjunctival cyst?

A:
A conjunctival cyst is a harmless but uncomfortable transparent sac formed on the conjunctiva of the eye, which is difficult to see with the naked eye. The conjunctiva on your outer eye is for keeping eyes lubricated with tears and mucus, as well as preventing germs from entering eyes.

Symptoms

Conjunctival cyst usually is asymptomatic, especially when it’s very small in the early stage.

Develop as the disease, appear gradually be:

  • Itching
  • Redness
  • Excessive watering of the eye
  • Dryness of the eye
  • Swollen eyelid
  • Whitish appearance of conjunctival

Causes

Conjunctival cyst is generally classified into two types: retention cyst and inclusion cyst.

  • Retention cyst is typically caused by a buildup of eye secretions that blocks duct.
  • Inclusion cyst appears when epithelial cells are displaced into the substantia propria as there would be a cystic cavity filled with clear fluid.

Treatments

First of all, doctors will suggest a regular follow-up observation since conjunctival cysts did not bring any trouble to the patient in the early stage.

With the growth of cysts, medications and eyes drops would be used to relief symptoms.

Then, in the case when the cyst continues to grow in size, the cyst would be removed through a minor surgical procedure under local anesthesia.

If have any further questions, please contact your doctor.
