| Summary: | The Main objective of the present study is to review the literature about the chemical composition and the formation of dacryoliths.
Dacryoliths are calculi of the lacrimal system observed incidentally during dacryocystorhinostomy. Theories about the formation of
dacryoliths mainly suppose that dacryoliths are simply a secondary phenomenon resulting from a lacrimal pathway obstruction and
accumulation of debris. Inflammation caused by fungi, most commonly Candida albicans, an eyelash within the sac, or adrenalin use are
also considered to be potential causes. It was also reported that the unstable concentrations of electrolytes rather than the supersaturation
of some electrolytes are related to the pathogenesis of dacryoliths. Chemical analysis of the dacryoliths in studies had revealed calcium,
magnesium, potassium, sulfur, and some phosphorus. Atomic absorption spectrophotometric investigations demonstrated organic proteins
and, to a much lesser extent, inorganic material. (Turk J Ophthalmol 2013; 43: 186-9) |
