The absorptive capacities of 4 commercially available tear test strips were determined and compared with 5-mm X 40-mm strips of #41 filter paper. Significant differences in the absorption of water over a given time interval were found in 3 of the groups tested. Major inconsistencies were found only within 1 lot of tear test strips from a single manufacturer. Tear test strips from this lot consisted of 2 distinct populations that were distinguishable by transillumination. Strips with widely spaced horizontal lines had the same absorptive capacity as the filter paper, whereas those with fine lines consistently absorbed less water. The clinical importance of this discrepancy was verified by comparing measurements of tear production in 6 normal dogs.
