Welder's maculopathy represents a form of photochemical damage to the retina and is characterized by involvement of the outer retinal layers. Fourier-domain optical coherence tomography (FD OCT) imaging was performed in 5 eyes of 3 patients with clinical findings suggestive of welder's maculopathy in occupational welders. Clinical examination was characterised by a faceted foveal lesion and the FD OCT line scan images showed a distinct discontinuity of the photoreceptor inner and outer segment (IS/OS) junction. The external limiting membrane (ELM) and the retinal pigment epithelial (RPE) layer remained intact at the site of IS/OS defect. FD OCT imaging offers a non-invasive way of evaluating the microstructural changes at the fovea in welder's maculopathy.
焊工黄斑病变是视网膜光化学损伤的一种形式，其特征是外视网膜层受累。对3名职业焊工中临床发现提示有焊工黄斑病变的患者的5只眼睛进行了傅里叶域光学相干断层扫描（FD OCT）成像。临床检查的特征是有小面状的黄斑病变，FD OCT线扫描图像显示光感受器内段和外段（IS/OS）交界处有明显的连续性中断。在IS/OS缺损部位，外界膜（ELM）和视网膜色素上皮（RPE）层保持完整。FD OCT成像提供了一种非侵入性方法，用于评估焊工黄斑病变患者黄斑区的微观结构变化。
