Primary | cornea innervation | The participants will undergo HRT in vivo confocal microscopy. It is a laser scanning confocal microscope, operating by scanning a 670 nm laser beam in a raster pattern over the field of view. The system uses a high numerical aperture 63x objective lens (0.9 NA), and produces images with high contrast and better axial resolution (7.6 µm) than other in vivo confocal systems (9 µm for the TSCM and 24 µm for the Confoscan). The HRT-RCM provides new built-in software for 3D imaging of the corneal structure. Quantitative imaging of the subbasal nerve plexus could be per-formed by CCMetrics system, a custom software program developed at the University of Manchester. | 30 min | |
Primary | Blinking reflex | Blinking rates manually calculated by two different research personnel and Tobii Pro X3-120 under two conditions: viewing preset film on the laptop and casual conversation with interviewer. | 30 min |
