A male welder who had been working in an industrial machine plant for more than 20 years experienced acute intense pain in his left eye with continuous lacrimation while performing arc welding in 1997. Later in 1997, at the age of 39 yr, macular edema was found in his left eye. He was diagnosed with macular degeneration (MD) of the left eye in 2002, and with right eye MD in 2004. Radiation in the visible and near infrared (IR) spectra penetrates the eye and is absorbed by the retina, possibly causing thermal or photochemical damage. Such retinal damage may be permanent and, therefore, sight-threatening. The young age and history of an acute painful eye injury are not consistent with age related macular degeneration (AMD) but rather is likely maculopathy caused by welding arc exposure.
一名在工业机械厂工作20多年的男性焊工，1997年在进行电弧焊接时左眼突然剧痛并持续流泪。1997年晚些时候，39岁的他被发现左眼黄斑水肿。2002年他被诊断为左眼黄斑变性（MD），2004年右眼也出现MD。可见光谱和近红外（IR）光谱中的辐射会穿透眼睛并被视网膜吸收，可能导致热损伤或光化学损伤。这种视网膜损伤可能是永久性的，因此会威胁视力。患者年轻且有急性眼外伤疼痛史，不符合年龄相关性黄斑变性（AMD），而更可能是由焊接电弧暴露引起的黄斑病变。
