1, Chalazions are lipogranulomas of either a meibomian gland or a Zeis gland.

2, It can be divided into anterior (eyelashes and follicles) or posterior (meibomian gland orifices) inflammation.

3, During the follow up period, meibomian gland orifice obstruction, dry eyes, corneal abrasion with foreign body tract were noted.

4, Eversion of the eyelid may show a dilated meibomian gland.

5, Chalazion is a granuloma that forms in the eyelid due to blocked secretions from the Meibomian gland. Inflammation of the eyelid may result.

6, No significant difference was found on the expression of P(53) protein between primary and metastatic sites in 3 paired samples of meibomian gland carcinoma.

7, Evaporation is affected by many factors such as temperature of the ocular surface, function of the Meibomian gland, relative humidity, air quality, exposed eye diseases and wearing of contact lens.
