Hordeolum internum upper eyelid – http://id.who.int/icd/entity/625555304

This is a cyst in the eyelid that is caused by inflammation of a blocked meibomian gland, usually on the upper eyelid. Chalazia differ from styes (hordeola) in that they are subacute and usually painless nodules. They may become acutely inflamed but, unlike a stye, chalazia usually point inside the lid rather than on the lid margin. This diagnosis is of the upper eyelid.
