Table 1.
The lines list the techniques that are covered in this review, the columns list the different parameters that can be assessed. LIPCOF = lid parallel conjunctival folds, OCT = Optical coherence tomography, IVCM = in vivo confocal microscopy, NITFBUT = non-invasive tear film break-up time. * requires instillation of fluorescein.
