what causes hordeolum internum left lower eyelid
The ICD code H000 is used to code Stye. An external stye or sty /ËstaÉª/, also hordeolum /hÉËrËdiËÉlÉm/, is an infection of the sebaceous glands of Zeis at the base of the eyelashes, or an infection of the apocrine sweat glands of Moll. External styes form on the outside of the lids and can be seen as small red bumps. Internal styes are infections of the meibomian sebaceous glands lining the inside of the eyelids. They also cause a red bump underneath the lid with only generalized redness and swelling visible on the outside.
