Schirmers-I test with and without modifications (lipid extracted paper and replacement of paper).
The lacrimation rate of 12 persons was measured by the Schirmer-I test and by two modifications of the test. The modifications used were: 1. the use of lipid extracted standardized Halberg paper (in a mixture of chloroform and ethanol), 2. replacement of the test paper in the conjunctival sac if no lacrimation was observed within 2 min. We could not detect any change in the variation of results between the different modifications or set-ups, and consequently the modifications were considered as being of little clinical value compared to the original test.
