Rationale: Ocular siderosis is arrested by the removal of intraocular foreing body (IOFB). The progression of ocular siderosis is very rare and few reports demonstrate the optical coherence tomographic (OCT) findings. Patient concerns: A 55-year-old Asian man presented to our clinic with the chief complaint of decreased vision in his left eye for 5 months. On slit lamp examination of the left eye, the corneal stroma had a rust-colored hue, and the retina was not visible due to vitreous opacity. An orbital computed tomography was ordered considering the possibility of left IOFB, which confirmed the presence of a vitreous IOFB. On the next day, he had a continuous curvilinear capsulorrhexis with phacoemulsification and intraocular lens implantation, pars plana vitrectomy, and removal of IOFB in the left eye. Six years later, he revisited our clinic. On slit lamp examination, the corneal haziness had worsened, and the iris showed heterochromia resembling the spokes of a wheel in the left eye. Diagnosis: Ocular siderosis. Intervention: Anterior and posterior segment OCT was performed. Outcomes: The anterior segment OCT showed linear hyperreflectivity on the anterior corneal stroma just beneath the Bowman's layer. The posterior segment OCT showed inner retinal degeneration observed at the parafoveal area. Lessons: Ocular siderosis progression can happen after the removal of IOFB. The swept source OCT might be useful to assess the cornea and retina in ocular siderosis patient with corneal haziness.
