Handheld reflectance confocal microscopy for the diagnosis of conjunctival tumors.

Purpose: To evaluate whether the handheld in vivo reflectance confocal microscopy that has been recently developed for the study of skin tumors is suitable for the diagnosis of conjunctival tumors.

Design: Prospective study, observational case series.

Methods: We prospectively evaluated the reflectance confocal microscopy features of 53 conjunctival lesions clinically suspicious for tumors of 46 patients referred to the University Hospital of Saint-Etienne (France) by using the handheld device.
