Schirmer tear test (STT) values in 79 cats without ocular discharge and without changes in the conjunctiva and the cornea, and intraocular pressure (IOP) values in 147 cats without changes in the cornea and anterior chamber. Influence of age and comparison to known reference values (test value) with the one sample t-test are shown

	Mean	Minimum	Maximum	Median	Influence of age	Test value	P value
STT (mm/min)	15.8 ± 4.8	7	33	15.5	P = 0.025	13.7 5	P <0.001
IOP (mmHg)	16.5 ± 5.0	6	33	16.5	P = 0.5	20.74 21	P <0.001
