Sjogren’s syndrome (Sicca Syndrome) is mainly characterized by the presence of dry eye disease (DED). The diagnosis of DED in patients with Sjogren’s syndrome has been limited to tests such as the Schirmer test, tear breakup time (TBUT), and corneal stains; however, currently we can evaluate the functional unit in detail lacrimal, which is affected in patients with dry eye and Sjögren’s syndrome; thanks to technology that provides objective details for this difficult diagnostic. The newer evaluations that provide the greatest diagnostic value for Sjogren’s syndrome are: noninvasive keratograph tear rupture time (NIKBUT), tear meniscus height (TMH), Schirmer’s test, meibography, ocular surface disease index (OSDI), Vital stains of the ocular surface, Matrix Metalloproteinase 9 (MMP-9), Tear osmolarity (TearLab); all of these are important complements to the existing tests, which, although less objective, are not substitutable.
