In this case presentation, we present a young vegan patient who developed a CRVO secondary to severe iron-deficiency anaemia (IDA) attributable to menstrual losses and limited iron intake. CRVO is a rare complication of IDA. With rising calls for sustainable diets and rising evidence for a plant-based diet, there has been a rise in popularity of such diet forms. While there are ocular benefits from this diet trend, the potential for nutritional deficiencies including iron needs to be monitored especially in susceptible individuals. Iron is essential for retina metabolism and function; however, excess iron contributes to disease states in the eye. Therefore, supplementation needs to be judicious.

因植物性饮食和月经过多而导致的严重缺铁性贫血继发的视网膜中央静脉阻塞：一例

在此病例报告中，我们介绍了一名年轻的纯素食患者，该患者因月经丢失和铁摄入量有限而继发于严重缺铁性贫血（IDA）继发的CRVO。CRVO是IDA的罕见并发症。随着人们对可持续饮食的要求不断提高，以及对基于植物的饮食的要求不断提高，这种饮食形式的受欢迎程度也在增加。尽管从这种饮食趋势中可以得到有益的视觉效果，但尤其是在易感人群中，需要监测包括铁在内的营养不足的可能性。铁对于视网膜的新陈代谢和功能至关重要。但是，铁过多会导致眼部疾病。因此，补充必须明智。
