RÉSUMÉ
The animal model of the bulbar conjunctival and pral microcirculation disturbance induced by high molecular weight dextran in rabbit were reported In this experiment.The interre'ationship between the bulbar conjunctival microcired ation disturbance and the pial miciocirculation disturbance, has been observed. We found that the occurrence of the buibar conjunctival microcirculation was earlier than the pial microcirculation. The degrees of abnormal bulbar conjunctival micro-circulation were more prominent. than that of the pial one, however, the degrees of erythrocyte aggregation in the bulbar conjunctiva Was similar to that of the cerebral microcirculation. The experiment showed the bulbar conjunctival microciculation disturbance, to some degree may reflect the degree of the cerebral microcirulation disturbance in living animals.
