A chalazion is lesion or bump that occurs on the eyelid. It is caused by a blockage of the glands within the eyelid. The blockage causes the glands to swell and this leads to redness, inflammation, and pain. These lesions often resolve on their own with conservative treatment such as warm compresses or medicated ointment, but sometimes they need to be surgically incised and drained. Our specialist can examine the lesion and determine the best treatment.
