Lakrimal Kese Dakriolitleri-Patogenez ve Bileşim

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