摘要：Purpose To investigate the function of the fellow eye in patients with unilateral nonarteritic anterior ischemic optic neuropathy (NAION). Methods From 2009 to March 2018, 18 patients with NAION who underwent bilateral visual field examinations and follow-up visits at least two times were enrolled in this study. Initial visual acuity, final visual acuity, degree of visual field defects, the cup-disc (C/D) ratio of the fellow eye, and the presence or absence of cardiovascular disease was retrospectively analyzed using medical records. Results 0.3 and < 0.3. The visual field defect was improved significantly from −4.92 dB to −2.37 dB in the group with optic disc ratios < 0.3 ( p = 0.013). When the changes in visual field defects were analyzed according to the presence or absence of cardiovascular disease, the visual field defects were improved from −5.65 dB to −4.49 dB in patients with cardiovascular disease, and improved from −3.69 dB to −1.46 dB in patients without cardiovascular disease ( p = 0.025 and p = 0.021, respectively). Conclusions In patients with unilateral NAION, reduced function in the fellow eye may appear temporarily, so a visual field examination should be performed in both eyes. The possibility of incipient NAION should be considered in patients with visual field abnormalities in the fellow eye.
