A 16-year old Liberian female presented with sudden monocular blindness. Physical examination and laboratory investigations were normal except that the patient had homozygous B-Thalassemia (HbA 58%, HbF 5% and HbA2 7.0%). Family study revealed that both parents had B-Thalassemia trait. We feel that the association of sudden monocular blindness with homozygous B-Thalassemia which has not been reported before, is not fortuitous but causal. It is therefore suggested that homozygous B-Thalassemia be added to the list of haemoglobinopathies (HbAS, SS and SC) that have been reported to cause blindness as complication.
一名16岁的利比里亚女性出现突然的单眼失明。体格检查和实验室检查均正常，只是该患者为纯合子β地中海贫血（HbA 58%，HbF 5%，HbA2 7.0%）。家族研究显示父母双方均有β地中海贫血特征。我们认为，此前未被报道过的突然单眼失明与纯合子β地中海贫血之间的关联并非偶然，而是存在因果关系。因此建议将纯合子β地中海贫血添加到已报道可导致失明并发症的血红蛋白病（HbAS、SS和SC）列表中。
