Arms Assigned Interventions
Active Comparator: Enhanced External conterpulsation
Enhanced external counterpulsation (EECP) is a noninvasive modality for the treatment of ischemic cardiovascular disease. EECP therapy is done by sequential inflation of 3 sets of cuffs wrapped around the lower extremities during diastole and deflation of the cuffs during systole.
Device: Enhanced external counterpulsation
EECP is performed for 1 hours every day, for a total of 36 hours.
Other Name: EECP
Drug: Aspirin
Standard drug therapy
Other Name: aspirin
Active Comparator: aspirin
The subjects with Anterior ischemic Optic Neuropathy received aspirin therapy.
Drug: Aspirin
Standard drug therapy
Other Name: aspirin

Detailed Description:

Patients with Anterior Ischemic Optic Neuropathy are randomized into two groups: one group receive standard medical treatment for ischemic optic neuropathy, the other group plus EECP therapy besides standard medical treatment.
