Using paired t-test statistical analysis,authors studied the features of hemorrheology in 13 cases of anterior uveitis,16 cases of pan-uveitis,and 15 cases of Behccedil;et' syndrome.The study showed that serous viscocity(at 230 s-1)in anterior uveitis patient group was higher than that of the control group,P＜0.02; that blood viscocity at high shear rate(230 s-1)in pan-uneitis patient group was markedly elevated and the difference between patient and control group was sighificant,P＜0.005; and that blood viscocity at both high(230 s-1)and low shear rate(5.75 s-1)in Behcet' syndrome grou was elevated,and the differences were significant as compared to the controls(P＜0.01,P＜0.05).the high blood viscocity in uveitis and Behcet' syndrome patients was analyzed and discussed in the paper.We thought that the treatment for uveitis and Behcet' syndrome should include lowering blood viscocity and improving the plasticity of red blood cells. （Chin J Ocul Fundus Dis,1993,9:70-72）
