KBI has established a step-wise screening system to identify the dry eye disease (DED) in non-human primates (NHPs). This model has been successfully used for the evaluation of pharmacological efficacy, safety and pharmacokinetics. 

As illustrated below, a range of evaluations tools are available for the detailed evaluation of this eye disease at KBI, including the Schirmer's test, measurement of tear film breakup time (TBUT), staining of corneal fluorescein and examination of meibomian glands.
