Hello,

There are various reasons which could appear as cyst on the eye. Some of the common ones are-

• hordeolum or sty
• meibomian cyst
• trachoma cysts on the lids

These usually appear on the lid and a sty can be very painful. The first two ( sty and meibomian cyst ) are harmless though it requires treatment to get rid off.

Here is more information on how to treat them

In addition to this, there can be other cysts which appear on the eye ball itself. This may be benign as well as malignant and would require a consultation by an eye doctor. Trachoma also needs to be treated by an eye doctor as it can cause scarring and damage to the eyelids.

If there is a single cyst on the eye lid, it is more likely to be a sty or meibomian cyst. In that case you could use eye drops and apply heat on the area as directed in the links. If there is no relief within a day, go to an eye doctor.

IF there are multiple cyst on the lid or the cyst is on the eye, do not self treat and go to the eye doctor for further treatment.
