Fundoscopy revealed posterior vitreous detachment in the right eye and a pigmented, slightly elevated lesion on the paramacular area of the left eye surrounded by diffuse atrophy (Figure 1A (Fig. 1)). Fundus autofluorescence showed a wide hypoautofluorescent area due to the diffuse RPE atrophy with regular borders and hyperautofluorescence along the margin of the pigmented lesion (Figure 1B (Fig. 1)).

B-scan ultrasonography disclosed a preretinal hyperechoic lesion with posterior shadowing (Figure 2A (Fig. 2)). Optical coherence tomography (OCT) showed the preretinal localization of the foreign body with posterior shadowing (Figure 2B (Fig. 2)). Neither USG nor OCT showed any choroidal mass (Figure 2 (Fig. 2)).
