Chalazion is a small, non-infectious lump that develops in the upper or lower eyelid due to the blockage of the meibomian gland, an oil gland in the eyelid. The meibomian gland produces fluid that lubricates the eye. While children do develop chalazions, they more commonly affect adults between the ages of 30 to 50.
There are almost one hundred meibomian glands in the eyelid, located near the eyelashes. When the duct that drains the gland is blocked, the fluid becomes backed up inside the gland and forms chalazion. It may also form as a result of an eyelid infection.
Chalazion symptoms usually include:
- Bump or lump in the upper or lower eyelid
- Tenderness of the eyelid
- Sensitivity to light
- Excessive tearing
- Blurry vision
Chalazion usually resolve on their own, over the course of time. It can take a few months before they disappear. To treat a chalazion, the following options are available:
- Antibiotic ointment
- Steroid injection
- Surgical drainage
While older children and adults may undergo the surgical drainage procedure in a doctor’s office under local anesthesia, general anesthesia is usually recommended for a chalazion removal in young children. If a chalazion recurs in the same place, a tissue biopsy may be conducted in order to rule out a more serious issue.
