Four patients each developed a reversible homonymous hemianopia caused by non-ketotic hyperglycemia. In two patients the homonymous hemianopia was the first manifestation of diabetes mellitus type 2. All four patients had abnormal MRI scans; in the three patients who had late follow-up scans the abnormalities resolved completely. In one patient the progressive visual field defect and unusual MRI findings initially caused concern for a tumor.
四名患者均出现了由非酮症高血糖引起的可逆性同向性偏盲。其中两名患者的同向性偏盲是2型糖尿病的首发表现。所有四名患者的MRI扫描均异常；在进行了后期随访扫描的三名患者中，异常完全消失。在一名患者中，进行性视野缺损和不寻常的MRI表现最初引起了对肿瘤的担忧。
