A 61-year-old man presented to the ophthalmology department having developed bilateral branch retinal vein occlusions. Baseline blood tests revealed no abnormality; however, subsequent investigations showed a raised plasma homocysteine (HC) level. The patient has been treated for refractory epilepsy for a number of years. Although antiepileptic medications have been shown to reduce folate levels and result in a raised HC level, this has not previously been shown to be to a level causing a retinal vascular event.
一名61岁男性因双眼视网膜分支静脉阻塞就诊于眼科。基线血液检查未发现异常;然而,后续检查显示血浆同型半胱氨酸(HC)水平升高。该患者多年来一直患有难治性癫痫。尽管抗癫痫药物已被证明会降低叶酸水平并导致HC水平升高,但此前尚未证明会升高到导致视网膜血管事件的水平。
