RESUMO
: This report describes the spontaneous extrusion from between the eyelids of a presumed conjunctivolith in a patient with resolving severe herpes zoster ophthalmicus. A 57-year-old man presented for ophthalmologic assessment and management due to severe left herpes zoster ophthalmicus. At one subsequent ophthalmologic assessment, a conjunctivolith spontaneously egressed the lateral commissure of the OS when the lateral fornix was inspected. The conjunctivolith was retrieved from the floor of the consulting room. Electron microscopic analysis and energy dispersive spectroscopy was undertaken to determine its composition. Scanning electron microscopy showed that the conjunctivolith was composed of carbon, calcium, and oxygen. Transmission electron microscopy diagnosed Herpes virus within the conjunctivolith. Conjunctivoliths, or possible lacrimal gland stones, are a very rare phenomenon, and their etiology is currently unclear. In this case, there was likely to have been an association between herpes zoster ophthalmicus and the conjunctivolith.
