A 48-year-old man presented following an episode of sudden onset simultaneous inferior altitudinal visual loss in his left eye and visual obscuration with shimmering in the inferonasal quadrant of the right eye. Clinical examination demonstrated left superior hemiretinal artery occlusion and an area of focal dynamic spasm along the right superior temporal branch retinal artery, the arteriolar spastic cycle was about 2 sec in duration. Hematological (including complete blood count, thrombophilia screen, vasculitic screen and serum magnesium), carotid, and cardiac investigations were normal. He was given acetazolamide 500 mg orally, timolol maleate 0.5% eye drops once daily and sublingual amyl-nitrate 0.8 mg, and maintained on felodipine 10 mg/day and aspirin 100 mg/day. The area of focal arteriolar spasm in the right eye resolved over two months. To our knowledge there are no prior reports of photographically documented dynamic focal retinal vascular spasm on a MEDLINE and PUBMED search.
一位 48 岁男性，左眼突发同时性下方水平性视野丧失，右眼鼻下象限出现闪烁性视野遮挡前来就诊。临床检查发现左眼上方视网膜动脉阻塞，右眼上方颞侧视网膜动脉有一处局灶性动力性痉挛，其动脉痉挛周期约为 2 秒。血液学（包括全血细胞计数、血栓形成倾向筛查、血管炎筛查和血清镁）、颈动脉和心脏检查均正常。给予患者乙酰唑胺 500mg 口服、马来酸噻吗洛尔滴眼液 0.5%每日一次滴眼、亚硝酸异戊酯舌下含服 0.8mg，并维持使用非洛地平 10mg/天和阿司匹林 100mg/天。两个月后右眼局灶性动脉痉挛区消退。据我们所知，在 MEDLINE 和 PUBMED 检索中，没有关于动态性局灶性视网膜血管痉挛的照片记录的先前报告。
