Siderosis is a chronic degenerative process created as a result of the interaction of iron particles and tissues of the eye. Siderosis manifests itself in anterior capsular cataract with radial deposits of iron on the front of the lens capsule, reddish discoloration of the iris, secondary glaucoma and pigmented retinopathy. Siderosis of the eye usually occurs as a consequence of the presence of an intraocular foreign body. The aim of our paper is to present a case of Siderosis bulbi as a consequence of the untimely diagnosed foreign body. In September 2011, a 51-year-old man was referred to our department because of reduced vision in his right eye. The patient’s medical history states that he had an eye injury working with metal hammer 10 years ago. More than a year ago, he noticed a gradual loss of the sight in the right eye. We find a heterochromia iridis and the ptosis of the right upper eyelid. Using the slit lamp examination, it could be seen that the lens was not homogeneously blurry, with visible brownish diffusely arranged precipitates on the endothelium of the cornea, and clusters of pigment on the front capsule of lens. The existence of intraocular foreign bodies was suspected, and the patient was sent for further diagnostic evaluation, which confirmed the referral diagnosis. After the preoperative preparation, the Phacoemulsificatio, Vitrectomia via the pars plana, Extractio corporis aliens, Endolaserphotocoagulatio were done. The twelfth day of hospitalization, the visual acuity in the right eye with +12.0 diopters was 0.2. After discharge, the patient was sent to regular checkups. Visual acuity 3 months after surgical treatment was 1.0 with 12.0 diopters of correction. Siderosis bulbi usually occurs as a consequence of the presence of intraocular metallic foreign body. Intraocular foreign body may hurt eye mechanically, cause an infection or demonstrate other toxic effects on intraocular structures. Once in the eye, foreign body can nestle in any of its structures: the anterior chamber of the eye, retina and horoidee. Siderosis caused by an intraocular foreign body requires detailed clinical history and diagnostic evaluation of the patient, as well as the removal of the foreign body. Finding of heterochromia iridis should be considered as a possible foreign body in the eye, particularly if there is a previous history of the eye injury. Early diagnosis and removal of the foreign body accelerates recovery and lead to an improved visual function. The goal of this thesis was to prove that even ten years after the injury, diagnosis and removal of foreign body from the eye can result in the full recovery of the visual function.
