Homonymous hemianopia is frequently associated with retrochiasmal lesions. Vascular etiology is the most common and usually evident on magnetic resonance imaging. When the results of neuroimaging are normal, there are other etiologies that we should consider, like nonketotic hyperglycemia (NKH). We report a 62-year-old female diabetic patient with headache, colour vision and sudden homonymous inferior quadrantanopia and elevated blood sugar levels with normal pH. The neuroimaging was normal and the visual lost improved after the correction of the hyperglycemia. NKH should be considered in patients with sudden and transient hemianopia and normal neuroimaging.
同向偏盲常与视交叉后病变相关。血管病因最为常见，通常在磁共振成像上很明显。当神经影像学结果正常时，我们应考虑其他病因，如非酮症高血糖（NKH）。我们报告了一名62岁的女性糖尿病患者，有头痛、色觉异常、突发同向性下象限盲，血糖水平升高且pH值正常。神经影像学检查正常，高血糖纠正后视力丧失有所改善。对于突发短暂性偏盲且神经影像学正常的患者，应考虑NKH。
