In vivo confocal microscopy findings of cornea and tongue mucosa in patients with Sjögren's syndrome.

INTRODUCTION AND OBJECTIVES: We aimed to investigate whether Sjögren's syndrome (SS) had distinctive findings in tongue confocal microscopy in a non-invasive manner. MATERIALS AND METHODS: This retrospective case-control study evaluated corneal and tongue confocal microscopy findings of the right eyes of 25 patients with aqueous deficient dry eye and 12 healthy volunteers without dry eye findings. There were a total of 14 patients diagnosed with SS-associated dry eye (SSDE), while 11 cases were evaluated as non-Sjögren dry eye (NSDE). RESULTS: A significant difference was observed in the dendritic cell count at the corneal subbasal nerve level between the SSDE and NSDE groups (P=.018). In SSDE group, the confocal microscopy images of dendritiform hyperreflective inflammatory cells in the tongue mucosa were in favor of inflammation. However, these findings were not found in patients with NSDE or in controls. CONCLUSIONS: This study showed that confocal microscopy provided a non-invasive evaluation of the inflammatory cells in the tongue of SS patients.

An atypical case of tularemia presented with pseudoptosis.

We report an unusual case of tularemia involving pseudoptosis associated with deterioration of the lymphatic drainage system extending from the upper eyelid to the preauricular lymph nodes. A 16-week pregnant patient was admitted with an absess on the neck, preauricular lymphadenopathy, and pseudoptosis on the left side. The micro-agglutination test was positive for Francisella tularensis antibody at a titer of 1/200. The absess was surgically drained and oral cefuroxime was given for 6 weeks. Two weeks after drainage, the pseudoptosis improved due to the recovery of lymphatic drainage system of the eyelid and remission of the absess on the neck. Our case report contributes to the medical literature on tularemia during pregnancy and informs healthcare professionals on the management of the infection in such cases.
