The presented case report concerns a patient with a foreign body in the orbital cavity – a fishing weight. After performing diagnostic tests, a multidisciplinary procedure was performed to remove the foreign body under general anaesthesia. Ophthalmologic consultation carried out after the procedure showed normal vision of the right and left eye. Penetrating foreign bodies of the orbit due to the variety of shapes and sizes, chemical composition and location, as well as potential serious consequences of such an injury require accurate diagnosis. This starts with determining the pathomechanism of the injury and selecting the appropriate radiological methods, and ends with a multidisciplinary approach to treatment.
