Dry eye is a common disease of older adults that produces symptoms ranging from mild discomfort to visual disturbances. Treatments range from lifestyle changes, use of eye drops, to surgical interventions. A nonhuman primate model of severe dry eye disease has been developed using rhesus macaques and employs the use of the Schirmer 1 Tear Test (STT-1). Pigtail macaques would likely be similarly suited as a model for this disease, however, no STT-1 values have been published for this species. Our objectives are to determine the normal range of STT-1 values in apparently healthy pigtail macaques, while considering age, sex, and type of sedation. The data consists of STT-1 values in each eye on 218 pigtail macaques, along with who performed the test, type of sedative used, and the age and sex of each monkey. Analysis of these data using t-tests, ANOVA and linear regression methods indicate that STT-1 values vary significantly between left and right eyes, type of sedation, and staff conducting the test. STT-1 values do not vary significantly by sex but may vary by age. We used the observed relationships to determine an overall 95% baseline interval of STT-1 values for healthy pigtail macaques, as well as individual 95% baseline STT-1 intervals that depend on sedation type and age.
