摘要：

The steady state viscosity as a function of shear rate was determined for eight commerical tear substitutes and compared with data for high molecular weight sodium hyaluronate solutions. The Zero shear viscosity at steady state varied more than 100-fold from about 2 to 300 cP. Many samples were Newtonian, while some samples exhibited a varying degree of shear thinning (psedudoplastic) behaviour. The results are discussed in realation to the rheological behaviour of normal tears and mucin. © 1990 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
