ABCD History |
A chalazion is a pediatric or adult eyelid disorder arising from one of the normal oil glands in the eyelid. Normal tears are composed of salt water sandwiched between a mucin layer next to the cornea and an oil layer on the outside to prevent evaporation. Each eyelid has about 25 oil glands. If the oil gets too thick, a plug forms in the pore to the eyelid gland near the base of the eyelashes. Oil gland plugs are more common with poor lid hygiene and certain influences of age, growth and hormones. If the plug does not clear with warm compresses, then oil breaks through the walls of the gland and spreads into the tissue of the lid. The immune system does not expect oil to be in the tissues and therefore mounts a reaction with white blood cells and circulation (inflammation) to expell, or surround the oil. A stye (hordeolum) is the early, hot red lid as a result of inflammation with lid oil. A chalzion is an older, walled-off lump in the eyelid. The chalazion resembles a rubbery "coconut;" there is oil (milk) in the middle surrouned by white blood cell granulomatous reactiuon (meat) with a gradually forming shell on the outside.Chalazions rarely require antibiotics but migh blur vision. If warm soaks several times per day does not clear a chalazion, surgery may be required to incise and drain the lump. | |||||
