Abstract:
Objective To observe the concentration of plasma endothelin (ET-1) in patients with nonarteritic anterior ischemic optic neuropathy(NAION) and investigate the relationship between ET-1 and NAION. Methods The plasma levels of ET-1 in 41 patients with NAION and 15 age-matched normal control subjects were measured by radioimmuoassay (RIA). The patients with NAION were divided into high papilloedema group, light papilloedema group, and recovery group according to the degree of papilloedema; and were divided into group1 (within 14 days), 2 (within 15-30 days), 3 (within 31-60 days), and 4 (within 61-180 days) according to the disease course. The plasma levels of ET-1 in different groups were detected and compared. Results The plasma level of ET-1 in patients with NAION was significantly higher than that in the normal subjects ( t=5.02,P
