UNASSIGNED: A 49-year-old woman presented with acute painless vision loss in her right eye and was found to have a branch retinal artery occlusion after taking prescribed dosages of phentermine for weight loss therapy. Fundus examination revealed retinal whitening in the distribution of the superior temporal branch retinal artery, and spectral domain optical coherence tomography demonstrated macular edema. Systemic evaluation was negative for cardiovascular, infectious, or autoimmune etiologies. Based on the retinal findings, the patient was diagnosed with phentermine associated branch retinal artery occlusion. She was followed for nine years with no further complications and her vision remained stable in the right eye.
UNASSIGNED: This case highlights that phentermine, a commonly used weight loss medication, could be associated with ischemic retinopathies. Thus, clinicians should be aware that retinal vascular occlusions may not only occur in those who use recreational amphetamines but also in patients taking the prescribed dosages of a weight loss medication like phentermine.
■一名49岁女性右眼出现急性无痛性视力丧失,在服用规定剂量的芬特明进行减肥治疗后发现视网膜分支动脉阻塞。眼底检查显示视网膜白化在视网膜颞上分支动脉的分布,谱域光学相干断层扫描显示黄斑水肿。心血管系统评估为阴性,传染性,或自身免疫性病因。根据视网膜的发现,患者被诊断为芬特明相关的视网膜分支动脉阻塞。她被随访了9年,没有进一步的并发症,她的右眼视力保持稳定。
■这个案例突出了芬特明,一种常用的减肥药,可能与缺血性视网膜病变有关。因此,临床医生应该意识到,视网膜血管阻塞不仅可能发生在使用娱乐性苯丙胺的患者中,而且也可能发生在服用规定剂量的减肥药如芬特明的患者中。
