[Hemorrheologic analyses of anterior ischemic optic neuropathy]
Objective:
To find the pathogenic factor of non-temporal arteritis anterior ischemic optic neuropathy (AION).
Methods:
Several items of hemorheology in 39 cases (19 males and 20 females) of acute non-temporal arteritis AION at papilloedema stage were examined and compared with that of the control group including normal comparable 20 males and 20 females.
Results:
The results showed that hematocrit (HCT), fibrinogen, low shearing viscosity, aggregation index, erythrocyte electrophoresis time were higher in the AION group than that of the control group (P < 0.01 or P < 0.05). Besides, high shearing viscosity and plasma viscosity in the female patient group are also higher than that of the control group (P < 0.01).
Conclusion:
The high blood viscosity is closely related to the pathogenesis of non-temporal arteritis AION.
