Conjunctival cysts cause the formation of a gap on the conjunctiva – a clear, thin tissue that encompasses the exterior of the eye. The main function of the conjunctiva is producing the tear fluid that moisturizes the eye.

Causes:
Usually, a conjunctival cyst occurs after you have had an infection – conjunctivitis or scleritis. However, such a formation occurs most often as a result of a trauma caused to the visual organ, even a small one (for example, after rubbing the eye). There are cases where the cyst appears for no apparent reason.
Diagnosis:
Diagnosis of conjunctival cyst is a simple one. It can be diagnosed within a simple consultation, without any special equipment. Visually it looks like a swollen ball placed on the outer surface. If left untreated, it can lead to conjunctive hyperemia, due to irritation caused by blinking. There are cases where these cysts can be detected only in the morning after waking up, then they are simply absorbed during the day and the next morning they reappear. For a deeper examination, eye biomicroscopy is performed using a slit lamp.
Treatment:
The method of treatment for conjunctival cyst depends on its size and location. If the cause is an infection – anti-inflammatory drugs are prescribed. In other cases, surgery may be performed.
Typically, small-sized cysts are removed by laser. During surgery, the surgeon's task is the complete excision of the cyst wall, otherwise it may relapse in the same place.
The intervention is performed under local anesthesia. The recovery period is short and is not included in the difficult category, therefore it virtually does not cause complications.
