“…[12] We reviewed 28 previously reported cases of intralenticular FB, the clinical features and treatment outcomes of which are summarized in Table 1. [3456789101112131415161718] The mean age at injury was 30 years; nearly all patients were male (27/28); most FBs were metallic (20/28). The cornea was the most frequent FB entry site (24/28), although sclera (2/28) and limbus (1/28) were also reported.…”

“…Other indications for surgery included anterior uveitis, glaucoma, lens subluxation, and ocular siderosis. [3456789101112131415161718] Four cases, described as follows, received surgery prior to any ocular complications developing: copper-containing FB that might have incited devastating inflammation; organic FB with a high risk of infection; patient drove heavy goods vehicles for which good vision was required; and patient's location was too far from the hospital preventing regular follow-ups. When making decisions regarding surgery, factors including FB characteristics, infection possibility, ocular complications, associated injuries, and patient's personal considerations were all assessed.…”

The purpose of this manuscript was to provide a better understanding of patients with intralenticular foreign bodies (FBs) and also to review the reported cases, including clinical presentation, diagnosis, management, and visual outcome. A 50-year-old male was referred to our clinic with suspected intraocular FB. Under slit-lamp examination, a full-thickness corneal wound with localized corneal edema at the temporal lower peri-limbal area was revealed. Seidel test did not indicate any wound leakage. The corresponding iris was depigmented, but there was no penetrating hole. The anterior chamber was deep with cells, but the lens, vitreous, and fundus were normal. B-scan ultrasonography and orbital computed tomography were performed, but no intraocular FB was detected. On the 2nd day, a zonal cortical cataract and posterior subcapsular cataract formed rapidly. Left-eye bare vision dramatically decreased from 20/100 to counting fingers. One month later, the patient received elective extracapsular cataract extraction. A fine metal thread was completely embedded in the lens; the lens and FB were removed together during the operation. The posterior capsule was not injured; an intraocular lens was implanted in the capsular bag. Two months postoperatively, left-eye vision had returned to 20/25. No adverse events were noted during the follow-up period. In addition to the case report, some 28 previously reported cases of intralenticular FB are reviewed here. Patient demographics, time and course of management, and visual outcome are all summarized and compared.

“…IOFBs following penetrating eye injury are common in most clinical cases, which can cause severe complications such as cataract, glaucoma, uveitis, retinal detachment, and endophthalmitis [ 6 ]. Intralenticular foreign bodies comprised only 5–10 % of all IOFBs [ 2 , 3 ]. The treatment management and outcome depend on several factors such as size, location, material type, risk of infection, and other intraocular damage [ 7 ].…”

“…Intraocular foreign bodies (IOFBs), with an incidence of about 18–41 % [ 1 ], are commonly encountered in cases of penetrating ocular trauma. However, the lens is not commonly involved, and the incidence of intralenticular foreign bodies is only 5–10 % [ 2 , 3 ]. Accurate localization of IOFBs is essential to evaluate the severity of the ocular lesion and to determine further management.…”

BackgroundThe accurate localization of intraocular foreign bodies (IOFBs) is very important for the management of ocular trauma patients. B-scan ultrasonography is usually used to detect IOFBs in the posterior segment. Here, we report three cases with IOFBs in the anterior segment near the posterior lens capsule, which were accurately localized by B-scan ultrasonography under dynamic transversal scanning.Case presentationAll three patients had a history of ocular trauma, and their clinical symptoms were compatible with the persistence of IOFBs. It was difficult to get a direct visualization of IOFBs with slit-lamp biomicroscopy because of opacities of the cornea and traumatic cataract. A computed tomography scan detected IOFBs in the anterior segment, but could not determine the exact location. Ultrasound biomicroscopy was performed but failed to show any IOFBs owing to the limited depth of penetration. B-scan ultrasonography was further applied but also failed to show any intraocular foreign bodies using axial scanning, a routine procedure of B-scan ultrasonography examination. However, using dynamic transversal scanning of B-scan ultrasonography, the accurate location of IOFBs was eventually shown to be embedded in the posterior lens cortex in case 1, adjacent to the posterior lens capsule in case 2, and located in the anterior vitreous close to the posterior lens capsule in case 3. Different surgical procedures were designed according to localization by B-scan ultrasonography, and all IOFBs were successfully removed.ConclusionB-scan ultrasonography is a simple and effective imaging modality in the localization of IOFBs in traumatic cataract. Transversal scanning is more suitable than axial scanning to detect IOFBs in the anterior segment near the posterior lens capsule.

“…[15] Intralenticular foreign bodies comprised only 5-10 % of all IOFBs. [16,17] The incidence of infectious endophthalmitis after retaining an IOFB has been reported to be 0-13.5%. [18] Several studies have shown that delayed removal of IOFB may end with poor visual and anatomical outcomes including the development of infectious endophthalmitis and retinal detachment.…”

BACKGROUND Knowledge of the effect of various foreign bodies in and around the eye with their complications is essential to prevent the blindness due to these metallic and non-metallic foreign bodies. MATERIALS AND METHODS We have analysed retrospectively several varieties of foreign bodies and their consequences, complications, at a clinic, situated near a large industrial area [related to iron and other metals]. This study has been done from 1997 to 2016. RESULTS Result of our study showed various types of foreign bodies, how they fell in eye, circumstances where one can get a FB in eye, their complications, cause of blindness due to these foreign bodies in rare situations. It is one of the largest study on external and internal FBs over the period of nearly 18 years, and the no. of FBs are 10,627. CONCLUSION Our study showed that most of the FBs are iron i.e. metallic in nature and the rest are like dust particles, vegetable particles, glass pieces, etc. Very few cases of the FBs were especially intraocular FB with ruptured globe leading to blindness. Awareness regarding prompt removal of FB and control of infection can reduce the incidence of blindness in these cases.
