Retained foreign body in nose following eye injury.

A man in his 60s presented with diminution of vision of the left eye with nasal bleeding after accidental fall. On examination his left upper eyelid was lacerated and left temporal sclera was punctured which was repaired under local anaesthesia after which he was discharged by ophthalmologists but continued to complain of pain and left nasal obstruction. A non-contrast CT of paranasal sinuses revealed fracture of medial wall of left orbit, left ethmoid haemosinus and a metallic foreign body (FB) in the septum and anterior face of sphenoid. Diagnostic nasal endoscopy performed to remove the metallic FB showed plastic splinters embedded in the mucosa of nasal cavity which was unexpected. Hence, the FB was removed in two sittings because of diagnostic dilemma.

Characteristics and scoring method of computed tomography in open-globe injuries.

BACKGROUND: Open-globe injuries (OGIs) remain the important cause of visual impairment and loss in all ages. Computed Tomography (CT) is a useful and common tool in the evaluation of the injuries of the eyeball. Prognostic value of CT scan in OGIs has been evaluated in many studies. However, there is no published consistent systematic scoring method for CT scan in OGIs. The purpose of this study was to evaluate the CT characteristics of OGIs and build a scoring method according to the CT scans which may aid the clinicians in management of OGIs. METHODS: Retrospective chart review of inpatients with clinical diagnosis of OGIs between 2017 and 2021 at Department of Ophthalmology, Henan Eye Institute, Henan Eye Hospital, Henan provincial People's Hospital (Zhengzhou, China). RESULTS: There were 1120 eyes from 1117 patients included in our study. The mean age was 35.7 ± 21.9 years with the range from 1 to 91 years. Significant male predominance was noted (889, 79.6%). CT scans of the OGIs were evaluated. Abnormality of anterior segment, posterior segment, and globe contour and volume were graded respectively. The most serious abnormality of anterior segment, posterior segment, and globe contour and volume were grade 3, 4 and 3 respectively and score 3, 4 and 3 respectively. Score of the CT scans of an open-injured globe ranged from 0 to 10. The correlation coefficient between the score and wound length was 0.798. The correlation coefficient between the score and final visual acuity was 0.799. In 78 eyes with 0 score, 70 eyes (89.7%) gained final visual acuity of 0.3 or better. In 31 eyes with 10 score, 20 eyes (64.5%) underwent evisceration of the eye globe and 10 eyes got visual acuity of no light perception and 1 eye lost to follow-up. CONCLUSIONS: CT scans is a useful tool in evaluating the severity of an open-injured globe. Scoring of the CT scans of an open-injured globe is a meaningful attempt and it may provide useful prognostic information regarding the outcome of an open-injured globe.

ULTRASOUND BIOMICROSCOPY AND ECHOGENIC EXTERNAL MARKER ASSISTED INTRAOCULAR FOREIGN BODY REMOVAL.

PURPOSE: We report a novel method of intraoperative localization of a retained anterior intraocular foreign body (IOFB), using a combination of ultrasound biomicrosopy and an insulated needle. METHODS: A retrospective case report of a 56-year-old man who presented with a right eye IOFB. RESULTS: On presentation, vision was decreased in the right eye to count fingers with a small subconjunctival hemorrhage, but no other signs of a penetrating laceration. Orbital CT revealed an IOFB, and the initial vitrectomy failed to retrieve the IOFB. Then, during the subsequent vitrectomy, using an ultrasound compatible needle and an ultrasound biomicrosopy, we were able to precisely locate and remove the small anterior IOFB. CONCLUSION: Retained IOFBs can lead to severe irreversible vision loss if not promptly removed. Ancillary imaging modalities and localization techniques can help locate occult IOFBs in difficult cases.

Incidental finding of a retained intracorneal wooden foreign body.

We present a case of an intracorneal wooden foreign body that remained undetected for 15 years following an ocular injury sustained during gardening. The patient presented with stable visual acuity despite the long-standing presence of a wooden splinter embedded in the cornea. Interestingly, Pentacam corneal tomography did not show any abnormalities despite the foreign body piercing through the corneal stroma and endothelium. This case may serve as an opportunity to re-examine the approach to managing chronic and stable intracorneal wooden foreign bodies and explore the implications of continued observation rather than surgical management.

Intraorbital Wooden Foreign Body in a Soldier.

The authors report a case of an intraorbital wooden foreign body that was misinterpreted as a radiolucent area of retained air on a computed tomography (CT) scan. A 20-year-old soldier presented to an outpatient clinic following an impingement with a bough while cutting down a tree. He had a 1-cm-deep laceration on the inner canthal area of his right eye. A military surgeon explored the wound and suspected a foreign body, but could not find or extract anything. Thereafter, the wound was sutured and the patient was transferred. An examination revealed an acutely ill-looking man with distressing pain in the medial canthal and supraorbital area associated with ipsilateral ptosis and periorbital edema. A CT scan showed a radiolucent area suspected to be retained air in the medial periorbital area. The wound was explored. Upon removal of the stitch, yellowish pus was drained. An intraorbital piece of wood measuring 1.5 cm×0.7 cm was extracted. The patient's hospital course was uneventful. Pus culture revealed growth of Staphylococcus epidermidis . Wood has a density similar to air and fat and can be difficult to distinguish from soft tissue both on plain x-ray films and CT. In this case, the CT scan showed a radiolucent area resembling retained air. Magnetic resonance imaging is a better method of investigation in cases of a suspected organic intraorbital foreign body. Clinicians should be aware of the possibility of retention of an intraorbital foreign body in patients presenting with periorbital trauma, especially those with even a small open wound.

High risk and low prevalence diseases: Open globe injury.

INTRODUCTION: Open globe injury (OGI) is a rare but serious condition that carries with it a high rate of morbidity. OBJECTIVE: This review highlights the pearls and pitfalls of OGI, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION: OGI refers to full-thickness injury to the layers of the eye. OGI can be caused by blunt or sharp trauma, and subtypes include penetration, perforation, intraocular foreign body (IOFB), globe rupture, or mixed types. OGI is more common in males and usually secondary to work-related injury, but in women it is most commonly associated with falls. Emergency clinicians should first assess for and manage other critical, life-threatening injuries. Following this assessment, a thorough eye examination is necessary. Computed tomography (CT) may suggest the disease, but it cannot definitively exclude the diagnosis. While point-of-care ultrasound (POCUS) is highly sensitive and specific for some findings in OGI, its use is controversial due to potential globe content extrusion. Management includes protecting the affected eye from further injury, preventing Valsalva maneuvers that could extrude ocular contents, updating tetanus vaccination status, administering broad-spectrum antibiotics, and ophthalmology consultation for surgical intervention to prevent the sequelae of blindness and endophthalmitis. CONCLUSION: An understanding of OGI can assist emergency clinicians in diagnosing and managing this sight-threatening traumatic process.

Management of a misidentified and misnumbered intraocular glass foreign body with an endoscope in a case of endophthalmitis.

An endoscope is a useful adjunct for the retinal surgeon to overcome haze of a compromised anterior segment. It allows early surgery in trauma and infections which translates to better results. Intraocular glass foreign body is a challenging condition, demanding highly skilled surgical expertise. We present endoscopic removal of an intraocular foreign glass body in a badly traumatised and infected eye. The surgical challenge was accentuated by an imaging misdiagnosis of 'twin metallic foreign bodies'.

Radiological characteristics of mixed composition intraorbital foreign body.

Orbital trauma is commonly complicated by retention of intraorbital foreign bodies. A 39-year-old man presented following a penetrating injury to the right orbit, with CT evidence of foreign bodies in the right anterior and posterior medial orbit. The foreign bodies were found to be a mixed composition of metal and wood. Characterising wood on CT imaging is difficult due to its radiolucency and low density, which can be mistaken for air in the setting of traumatic orbital emphysema. Increasing the window width on bone window settings can be used to distinguish wood from air, which is crucial for facilitating its complete surgical removal.

Intralenticular metallic foreign body 'locked-in' the posterior capsule and the utility of multimodal imaging.

Intraocular foreign bodies (FBs) are common ocular injuries reporting to the emergency services all over the world. The authors highlight the findings and surgical management of a case of intralenticular metallic FB following an injury while using chisel and hammer. The ocular path of the FB (2 mm) could be traced from a self-sealed corneal perforation, extending through the anterior capsule rupture, terminating at the posterior capsule, forming a posterior capsule tent with a part embedded in clear lens. Preoperative ultrasound biomicroscopy gave clues on posterior capsule integrity and the exact site of FB, and helped prognosticate and plan the surgical management of the case. The 'locked-in' FB was extracted after clear lens aspiration and posterior capsulorrhexis. The posterior capsule acted as a natural barrier between anterior and posterior segment, where the FB was found embedded.

Retained iron intraocular foreign body with late onset siderotic glaucoma: a clinical challenge.

Siderotic glaucoma is a rare and challenging clinical scenario caused by a retained iron intraocular foreign body (IOFB), which results in irreversible vision loss. Presented here is a case of secondary open-angle glaucoma in a 36-year-old man that was refractory to maximal medical therapy. A meticulous history and careful clinical examination revealed that he had a penetrating trauma 15 years ago, a self-sealed corneal entry wound, open angles, a retained encapsulated metallic IOFB and siderosis bulbi. Removal of the foreign body not only controlled intraocular pressure, but also improved vision.

Intraorbital wooden foreign body, legacy of a notorious scrap: a case report.

Wooden foreign bodies are notorious to be fragile and get retained as bits and bobs in the orbit. A 50-year-old woman presented to casualty with complaints of loss of vision and pain in the right eye associated with discharge from a wound in right eye upper lid. On imaging, a wooden foreign body was seen as continuous track of air. Meticulous dissection and search were done to remove bits and bobs of the wood. Patient, however, after 15 days of primary surgery reported with pus collection over wound site. Keeping suspicion of remnant wooden body piece(s), imaging and further exploration were carried out, removal of a 1 cm residual wooden piece was done. Retained wooden foreign body should always be suspected in postoperative cases of intraorbital wooden foreign body with infection. A close follow-up and knowledge of the same stay useful to remove any needless apprehension both of patient and surgeon.

Long-term ophthalmic anatomical and functional outcomes after surgical removal of intraorbital foreign bodies.

PURPOSE: To analyze the anatomical and functional ophthalmic parameters after the surgical removal of various intraorbital foreign bodies. METHODS: A retrospective analysis of medical records was performed featuring detailed history, ophthalmic examination, orbital computed tomographic scans, treatment details, and outcomes. The analyzed anatomical factors included extraocular movements, the position of the eyeball (proptosis, dystopia, and enophthalmos), and fullness of orbital sulci. The functional assessment was based on visual acuity, pupillary reactions, and diplopia. The outcomes were defined as complete, partial, and failure after a minimum follow-up of 1 year. RESULTS: Of 32 patients, the organic and inorganic intraorbital foreign bodies were surgically removed from 18 (56.25%) and 14 (43.75%) orbits, respectively. At presentation, anatomically the extraocular movement restriction, proptosis/dystopia/enophthalmos, and orbital sulcus fullness were noted in 26 (81.25%), 24 (75%), and 15 (46.88%), respectively. Functionally, diminished visual acuity, diplopia, and pupil abnormalities were seen in 27 (84.38%), 14 (43.75%), and 8 (25%), respectively. After intraorbital foreign body removal at a mean follow-up of 14 months, the improvement of anatomical factors (same sequence) were observed in 8 (30.77%), 20 (83.33%), and 12 (80%), respectively. In functional factors (same sequence), the improvement was noted in none (0%), 13 (92.86%), and 5 (62.5%), respectively. Hence, the majority of patients (n = 20, 62.5%) achieved partial success, while 8 (25%) had complete success. Four (12.5%) had treatment failure despite similar management protocols. CONCLUSION: The anatomical outcomes are better than the functional outcomes after surgical removal of the intraorbital foreign bodies. The visual acuity does not improve considerably after the surgical removal of intraorbital foreign bodies. Overall, the wooden intraorbital foreign bodies have poorer anatomical and functional prognosis.
