The thermal effects of laser cutting machines could damage the macula. A few studies in the literature have described macular injury induced by industrial laser burns. The aim of this study was to report the clinical, visual, and optical coherence tomography findings in a gold refinery worker with laser-induced maculopathy. A 21-year-old male gold refinery worker had vision loss in his right eye after using a laser cutting machine without wearing laser eye protection gear. At the first visit (24 h later), his best-corrected visual acuity was 7/10 in the right eye and 10/10 in the left eye. The anterior segment examination was normal. In fundus examination, focal, round, and yellowish lesion was detected within the fovea. The optical coherence tomography findings were foveal outer retinal disruptions and irregularities extending from the outer plexiform layer to the retina pigment epithelium. After 4 months, the best-corrected visual acuity had improved to 1.0, and the optical coherence tomography findings had resolved Os efeitos térmicos das máquinas de corte a laser podem danificar a mácula. Poucos estudos na literatura tem descrito a lesão macular por queimadura a laser industrial. Neste estudo, objetivamos relatar os achados clínicos, visuais e de tomografia de coerência óptica em um trabalhador de refinaria de ouro com maculopatia induzida por laser. O trabalhador da refinaria de ouro de 21 anos teve perda de visão no olho direito depois de usar uma máquina de corte a laser sem usar equipamento protetor ocular para laser. Sua acuidade visual melhor corrigida foi de 7/10 no olho direito e 10/10 no olho esquerdo na primeira consulta (24h depois). O exame do segmento anterior estava normal. No exame de fundo de olho, lesões focais, redondas e amareladas foram detectadas dentro da fóvea. Os achados da tomografia de coerência óptica revelaram rupturas na fóvea da retina externa e irregularidades estendendo-se da camada plexiforme externa ao epitélio pigmentar da retina. Após 4 meses, a acuidade visual melhor corrigida melhorou para 1,0 e os achados da tomografia de coerência óptica foram revigorados.
