“…In some cases, IOFBs (e.g., in the anterior chamber angle, embedded in the iris or lens, or on the pars plicata) cannot be visualized clinically, but can be detected by careful UBM examination [16–18]. Other indications of a possible IOFB include small self-sealing wounds, iris transillumination defect, iris heterochromia, irregular pupil, and focal lens opacities.…”

BackgroundAn occult foreign body may be retained in patient with small self-sealing wound and no decreased visual acuity without complete examination. Here we report a case of a retained occult ferrous iris foreign body detected incidentally during pterygium examination.Case presentationA 69-year-old man presented to our ophthalmology department because of foreign body sensation and persistent redness in both eyes for 2 years. In the left eye, a pterygium, paracentral corneal opacity and a vertically oval pupil were observed. Ultrasound biomicroscopy and gonioscopy revealed a retained metallic-like foreign body partially embedded in the inferior peripheral iris. Pterygium surgery and the removal of the retained iris foreign body were performed simultaneously. No recurrent pterygium or residual foreign body was found during follow-up.ConclusionsA thorough history should be obtained and complete physical examination should be performed in patients with ocular self-sealing wounds to prevent missed intraocular foreign bodies, which may result in potential sight-threatening ocular complications.

“…Unfortunately, with a 5.0-mm depth of penetration, it is difficult for UBM to detect IOFBs in the posterior lens [ 12 ]. In contrast, AS-OCT can visualize up to a depth of 6.0 mm, to determine the location and size of the intralenticular foreign body [ 13 ].…”

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.

“…Traumatic cases are often challenging with grossly disturbed lenticular and perilenticular anatomical orientations; hence, ASOCT paves the way for surgeons to formulate a customized treatment strategy in each case. [21][22][23] In a large case series, Tabatabaei et al compared SS-ASOCT with UBM to Figure 3 In the next stage of mature cataract, the separation becomes more advanced with little collection of liquefied material and minimal anterior lens bulging. This is the stage of established lamellar separation.…”

Modern-day cataract surgery has achieved equivalence with refractive surgery, thus requiring surgeons to perform all possible pre-emptive exercises to mitigate intraoperative complications. In this direction, we possess a tremendous amount of technology to understand the preoperative status of the lens. Anterior segment optical coherence tomography (ASOCT) is one such tool, which has played a distinctive role in imaging various forms of cataracts. In this review, we critically analyse the practical role of ASOCT in the preoperative and intraoperative periods from a cataract surgeon’s perspective. After a thorough literature assessment, it was substantiated that the cross-sectional imaging ability of ASOCT can demonstrate delicate anatomical and pathological lenticular changes in a visually and clinically comprehensible way. The objective grading of immature cataracts to intralenticular and posterior capsular details in mature/white, posterior polar, traumatic and other forms of cataracts paves the way for various practical innovations as and when required. Hence, preoperative more than intraoperative ASOCT-derived lenticular knowledge is of immense help in careful surgical planning, with improved complication rates.
