A chalazion is a small firm bulge in an eyelid caused by a blocked opening or infection of oil producing glands located in the upper or lower eyelids. They are frequently associated with a condition called Blepharitis.
Chalazia may be uncomfortable, unsightly and interfere with vision. They are initially red, swollen and tender.
In rare cases, chalazions can grow large enough to apply pressure on the eye causing droopiness of the eye lid and blurred vision.
Most chalazions will shrink after a few weeks without treatment, leaving a slight bulge. If the bulge does not shrink, one treatment option is to apply hot compresses to the eyelid. Sometime hot compresses alone can be effective in reducing the size of chalazion. If hot compresses are not effective then a surgery visit is needed for treatment. A doctor can either prescribe steroids to reduce the bulge, drain the chalazion manually. This procedure is done using local anaesthesia and is usually painless. An incision to drain the bulge is usually made on the inside of the eyelid, so that no visible scar remains. After the appearance of the bulge is greatly reduced, patients who experienced recurrence of chalazions that bulge they need to be examined by a pathologist to ensure that the condition is not serious.
