From: Dynamics of tear fluid desiccation on a glass surface: a contribution to tear quality assessment
Representative morphological pattern of a normal tear microdesiccate. Typical four-domain structure of a tear microdesiccate from a healthy individual. Those domains have been named respectively as zone I (the outermost, lower arrow), transition band (upper arrow), zone II (centripetally-oriented crystalloids) and zone III (major crystalloids at the center). Both zones II and III and their boundaries have been demarcated.
