Lacrimal sac dacryolith: a study wit atomic absorption spectrophotometry and scanning electron microscopy

Eur J Ophthalmol. 1996 Oct-Dec;6(4):478-80. doi: 10.1177/112067219600600425.


Dacryoliths are uncommon causes of partial or complete obstruction of the nasolacrimal drainage apparatus. We report our findings of a dacryolith that we studied by culture, light microscopy, atomic absorption spectrophotometry, and scanning electron microscopy. Although no fungi were recovered by culturing, hyphae-like structures were observed. No inorganic material was detected by atomic absorption spectrophotometry. Scanning electron microscopy of ultrastructure showed the stone was composed of lobes and lobules built on an amorphous core material.
