Clinical Trial Summary

Modifications of cell surface markers (including EMMPRIN) were observed in conjunctival epithelial cells during dry eye syndrome ; this study aims to describe the modifications of the repartition of these cell surface markers before and after initiation of a treatment.

Outcome
Type Measure Description Time frame Safety issue
Primary comparison of surface area of cell markers measured on conjunctival epithelial cells, in persons with and without severe eye dryness. Comparison of the mean surface in patients before treatment for eye dryness versus in persons with no eye dryness. Immunofluorescence analysed in confocal microscopy on conjunctival impression cytology. baseline
