To describe the optical coherence tomography (OCT) findings in two patients with welder's maculopathy.
Retrospective cases series. In addition to examination by slit lamp biomicroscopy, color fundus photographs and OCT images were obtained from patients with welder's maculopathy.
Both patients had a history of bilateral decreased central vision after welding without appropriate eye protection. Yellowish foveal spots developed in the acute stage, evolving over several months into well demarcated lamellar foveal defects with surrounding retinal pigment epithelium changes. OCT showed interruption of the inner high reflective layer (HRL) corresponding to the level of the outer neurosensory retina. These appearances are similar to those seen in solar maculopathy.
OCT shows disruption of the inner HRL in late welder's maculopathy. These appearances are similar to those seen in late solar maculopathy. OCT can be a useful tool in confirming the diagnosis and understanding the pathogenesis of photic maculopathy.
描述两名焊工黄斑病变患者的光学相干断层扫描（OCT）结果。
回顾性病例系列。除了通过裂隙灯生物显微镜检查外，还从焊工黄斑病变患者处获取了彩色眼底照片和OCT图像。
两名患者均有在未采取适当眼部防护措施的情况下焊接后双侧中心视力下降的病史。急性期出现黄斑部淡黄色斑点，数月后演变为边界清晰的板层黄斑缺损，并伴有周围视网膜色素上皮改变。OCT显示对应于外层神经感觉视网膜水平的内高反射层（HRL）中断。这些表现与日光性黄斑病变所见相似。
OCT显示晚期焊工黄斑病变内HRL中断。这些表现与晚期日光性黄斑病变所见相似。OCT在确诊和理解光性黄斑病变的发病机制方面可能是一种有用的工具。
