title: Siderosis oculi: visual dysfunctions even after iron removal: a role of OCT.
abstract: Four males with sidersosis oculi were reviewed. Vitreous/anterior chamber angle irons (cases 1 and 3) were misdiagnosed initially and discovered later. In case 2, the retina-incarcerated iron was long ignored. Exceptionally in case 4, the iron was encapsulated by using optical coherence tomography (OCT). Preoperatively, in cases 1 and 4, the injured eye's vision, electro-oculogram, and electroretinogram were reduced compared with the other eye. In three cases, field defects were relevant to their iron locations. Postremoval, iron-impaired retinal functions didn't obviously improve. Early iron removal seems vital. OCT identified iron encapsulation, ameliorating iron toxicity. Consistently, field defect in case 4 was nonprogressive.
