Epidemiology and characteristics of unintentional self-inflicted penetrating ocular injuries in children less than 6 years-old.

INTRODUCTION: Pediatric ocular injuries, notably unintentional self-inflicted penetrating ocular injuries in children under 6, pose a substantial public health concern, leading to visual impairment and psychological distress. With global prevalence indicating severe visual impairment or blindness in 2-14% of affected children, these injuries necessitate multiple surgeries and extended monitoring. Our study aims to analyze the epidemiology and characteristics of such injuries, emphasizing preventive measures, parental supervision, and timely medical intervention to mitigate their impact on young lives. METHOD: Conducted at Khalili Hospital in Shiraz, Iran, our retrospective study included 141 cases admitted between April 2018 and April 2023. Ethical principles guided data collection from medical records, encompassing demographic details, causative objects, ocular laceration specifics, surgical procedures, complications, and visual acuity assessments. RESULTS: The mean age of the participants in this study was 47.18 ± 16.48 months (ranging from 10 to 71 months), and the male to female ratio was 1.76:1 (90 vs. 51). Objects of injury mostly included knives (34.8%), wood (12.1%), and glass (10.6%), and the most common initial manifestation of injury was iris prolapse (56.7%), followed by traumatic cataract (46.8%) and limbus laceration (34.0%). Fifteen (10.6%) patients had a visual acuity better than LogMAR 0.5, 24 (17.1%) had finger count vision, 37 (26.2%) had hand motion, 7 (0.5%) had light perception, and 58 (41.1%) were uncooperative. Type of laceration and season of injury were associated with retinal detachment, and a longer time-to-visit was correlated with a higher risk of developing retinal detachment or endophthalmitis. CONCLUSION: Our study highlights the significant burden of unintentional self-inflicted penetrating ocular injuries in children under 6. Emphasizing preventive measures, parental supervision, and timely medical intervention, our findings underscore the potential psychological and visual consequences. This research advocates for parental education and safety measures to reduce the occurrence and severity of such injuries in this vulnerable population, promoting a healthier and safer environment for children.

An unusual cause of hemolacria: retained contact lens in upper fornix.

A 64-year-old male was referred for complaints of blood in tears and bloody discharge of unknown cause in the left eye. The patient was a chronic bandage contact lens (BCL) user. He had no history of recent trauma. A blood-stained BCL was present on the cornea in the left eye, which was removed. The ocular surface was dry with vascularization of the cornea. Double eversion of the upper eyelid with a Desmarre's retractor revealed a pyogenic granuloma with large papillae on the forniceal conjunctiva and a folded BCL hidden in the fornix. The folded BCL was carefully removed from the "upper fornix trap" and topical steroid eyedrops were prescribed.

Demystifying the role of magnetic resonance in identifying intraocular foreign bodies: a case of ocular siderosis.

BACKGROUND: Ocular siderosis (OS) is a significant cause of visual loss due to retained ferrous intraocular foreign bodies (IOFB). Despite its rarity, OS can lead to severe visual impairment if not promptly diagnosed and treated. This case is notable due to the occult nature of the IOFB, which was undetected by standard imaging modalities, emphasizing the critical role of magnetic resonance imaging (MRI) in such scenarios. CASE PRESENTATION: A 51-year-old Caucasian male presented with progressive vision loss in his right eye over 20 days. Best corrected visual acuity (BCVA) was 20/1000 in the right eye and 20/20 in the left eye. Intraocular pressure (IOP) was 9 mmHg in both eyes. Slit-lamp examination revealed a small linear corneal wound and an iris defect in the right eye, along with a cataract featuring brownish deposits on the anterior capsule. The left eye was normal. Fundus examination of the right eye was hindered by media opacities. Ultrasonography showed a flat retina and choroid with no detectable IOFB. Despite a strong clinical suspicion of OS, computed tomography (CT) did not detect any IOFB. MRI subsequently identified an artifact in the inferior sectors of the right eye, indicative of a metallic IOFB. Surgical intervention involved a 23-gauge vitrectomy, phacoemulsification, IOFB removal and silicon oil (SO) tamponade resulting in a fully restored VA of 20/20 and normal IOP one month post-operation. SO was removed 2 months later. The retina remained adherent with no PVR development, and optical coherence tomography (OCT) scans showed a normal macula. CONCLUSIONS: This case underscores the importance of considering OS in patients with unexplained vision loss and history of ocular trauma, even when initial imaging fails to detect an IOFB. MRI proved crucial in identifying the IOFB, highlighting its value in the diagnostic process. Early detection and surgical removal of IOFBs are essential to prevent irreversible visual damage. This case demonstrates that MRI should be employed when CT and ultrasonography are inconclusive, ensuring accurate diagnosis and timely intervention to preserve vision.

A case of prolonged corneal sulfur foreign bodies and review of literature.

BACKGROUND: This case mainly describes a relatively rare case of an old mineral-like corneal foreign body that existed for up to 20 years, and did not significantly affect the visual quality of the patient. CASE PRESENTATION: A 56-year-old male miner complained of right eye vision loss for 3 years, swollen and painful for 4 months. Admission examination: Best corrected visual acuity was no light perception in the right eye and 20/20 in the left eye. Anterior segment examination: A large number of spot-like grayish-brown mineral foreign bodies in the conjunctiva of the nasal conjunctiva, emulsified silicone oil floating in the anterior chamber, Corneal foreign bodies in the right eye were widely distributed in the upper cortex and the proelastic layer. There were fewer foreign bodies in the left cornea. Previous medical history, 20 years ago due to forging and burning sulphur mine explosion, resulting in a large number of ore foreign bodies in the conjunctiva of both eyes. As these corneal foreign bodies did not affect the visual quality of the patient, we adopted a conservative treatment plan, did not remove these foreign bodies, and only carried out symptomatic treatment for the patient's secondary ocular hypertension. The patient was followed up normally in the outpatient department, and no cornea-related complications occurred up to now. CONCLUSIONS: First of all, it is necessary to understand the source and nature of the foreign body in patients with corneal and conjunctival foreign body injuries. In the second, for the old corneal metal foreign body, when the patient's visual acuity is stable and there are no symptoms of corneal irritation and inflammatory reaction, it can be Conservative treatment or outpatient follow-up observation. In the end, corneal Optical coherence tomography imaging should not be ignored, which is very important for determining the depth of embedding and the location of the corneal foreign body.

Three-year epidemiological analysis of penetrating ocular traumatic endophthalmitis.

The characteristics of patients with endophthalmitis due to penetrating ocular trauma are still limited. The aim of the study was to fill these gaps among Chinese population. This retrospective study included patients diagnosed as penetrating ocular traumatic endophthalmitis between January 2016 to December 2018. During the past 3-year period, a total of 201 patients with antecedent penetrating eye injuries were evaluated. Of which, 42 (20.9%) patients presented a clinical course compatible with acute infectious endophthalmitis. 39 (92.86%) patients were males, and 15 (35.71%) patients had mechanical injuries from intraocular foreign body (IOFB), the rate of endophthalmitis due to IOFB was 13.43%, higher to the rate among patients without IOFB (7.46%). The duration between injury occurrence and endophthalmitis onset was 1 day in 10 (23,80%) patients; 2 to 7 days in 31 (73.80%) patients, and 7 to 14 days in 1 (2.38%) patient. After 1 year follow-up, best corrected visual acuity (BCVA) better than 20/400 was observed in 15 (35.71%) patients, counting fingers and hand move in 17 (40.48%) patients, light perception in 5 (11.9%) patients and no light perception in 5 (11.9%) patients, respectively. Patients with promising outcomes had better initial BCVA at baseline (P < .001). Endophthalmitis is a severe ocular infectious condition that may lead to irreversible vision loss. A greater attention must be paid to penetrating eye injuries within males, who had poor BCVA at baseline, particularly with obvious IOFB.

Bifid Pupil Iridodialysis Secondary to Airsoft Gun Injury.

This case report describes a diagnosis of iridodialysis in an 11-year-old boy who presented with decreased vision and inflammation after direct blunt trauma to the left eye.

Assessment of intraocular foreign body using high resolution 3D ultrasound imaging.

Ocular trauma often involves intraocular foreign bodies (IOFBs) that pose challenges in accurate diagnosis due to their size, shape, and material composition. In this study, we proposed a novel whole-eye 3D ophthalmic ultrasound B-scan (3D-UBS) system for automating image acquisition and improved 3D visualization, thereby improving sensitivity for detecting IOFBs. 3D-UBS utilizes 14 MHz Clarius L20 probe, a motorized translation stage, and a surgical microscope for precise placement and movement. The system's 3D point spread function (PSF) is 0.377 × 0.550 × 0.894 mm3 characterized by the full-width at half-maximum intensity values in the axial, lateral and elevation directions. Digital phantom and ex vivo ocular models were prepared using four types of IOFBs (i.e., plastic, wood, metal, and glass). Ex vivo models were imaged with both 3D-UBS and clinical computed tomography (CT). Image preprocessing was performed on 3D-UBS images to remove uneven illumination and speckle noise. Multiplanar reformatting in 3D-UBS provides optimal plane selection after acquisition, reducing the need for a trained ultrasonographer. 3D-UBS outperforms CT in contrast for wood and plastic, with mean contrast improvement of 2.43 and 1.84 times, respectively. 3D-UBS was able to identify wood and plastic IOFBs larger than 250 µm and 300 in diameter, respectively. CT, with its wider PSF, was only able to detect wood and plastic IOFBs larger than 600 and 550 µm, respectively. Although contrast was higher in CT for metal and glass IOFBs, 3D-UBS provided sufficient contrast to identify those. 3D-UBS provides an easy-to-use, non-expert imaging approach for identifying small IOFBs of different materials and related ocular injuries at the point of care.

Endoscopic transnasal approach to remove an intraorbital bullet: systematic review and case report.

Introduction: Intraorbital foreign bodies (IOFBs) represent a clinical challenge: surgical management can be controversial and different strategies have been proposed. When removal is recommended, depending on the location and nature of the IOFB both external and endoscopic approaches have been proposed, with significantly different surgical corridors to the orbit and different morbidities. Methods: We performed a literature review of cases of IOFBs that received exclusive endoscopic transnasal surgical treatment to evaluate the role of this surgery in these occurrences. We also present a case of an intraorbital intraconal bullet that was successfully removed using an endoscopic transnasal approach with good outcomes in terms of ocular motility and visual acuity. Results: A limited number of cases of IOFBs have been treated with an exclusive endoscopic transnasal approach. When in the medial compartment, this approach appears to be safe and effective. In our case, two months after surgery the patient showed complete recovery with no significant long-term sequelae. Conclusions: When feasible, an endoscopic transnasal approach for intraorbital foreign bodies represents a valid surgical technique with optimal outcomes and satisfactory recovery.

Report of endophthalmitis caused by Paradictyoarthrinium diffractum after plant trauma: A case involving left enucleation.

During outdoor work in April 2022, a 48-year-old man was stabbed by a tree branch and underwent intraocular foreign body extraction and repair of the scleral wound with sutures and amniotic membrane graft at a local hospital. Steroid therapy with prednisone was prescribed after a diagnosis of uveitis. Vitrectomy was performed in June 2023; a fungal culture was positive, and ITS sequencing identified the organism as Paradictyoarthrinium diffractum. Empiric antifungal therapy did not have an effect, and, because of deterioration of the condition, the left eye was enucleated in October 2023. P. diffractum is a mangrove host-specific saprophytic fungus that has not been reported in humans.

Management and Clinical Outcomes of Eyes With Posterior Segment Intraocular Foreign Bodies Seen at a Tertiary Referral Center.

BACKGROUND AND OBJECTIVE: This study aimed to identify the prognostic factors regarding the visual and anatomic outcomes of eyes with posterior segment intraocular foreign body (PS-IOFB). PATIENTS AND METHODS: The medical records of 95 patients who underwent pars plana vitrectomy and PS-IOFB removal between 2004 and 2021 were retrospectively reviewed. Data on anatomical and visual outcomes, as well as preoperative, intraoperative, and postoperative variables were statistically analyzed. RESULTS: The mean age of the patients was 31.9 ± 12.3 years. The mean follow-up time was 21.9 ± 28.3 months. The median time interval from trauma to IOFB removal was 9 days. In univariate analysis, there was a positive correlation between initial visual acuity (VA) and final VA (P < 0.001). A higher ocular trauma score (OTS) was significantly associated with both anatomical and functional success (P < 0.001). Linear regression analysis showed that OTS was not superior to initial VA in predicting final VA (r = 0.625 vs r = -0.601). Anatomic and functional outcomes were not affected by the injury site, nature of PS-IOFB, or timing of PS-IOFB removal (P > 0.05 for all). Subretinal IOFB location, the need for silicone oil tamponade, and endophthalmitis (P = 0.005, P < 0.001, P = 0.044, respectively) were risk factors for poor visual outcome. CONCLUSIONS: The initial VA, the extent of the initial ocular damage, and the presence of endophthalmitis are important prognostic factors for functional success.

Enlarging Orbital Rim Mass Due to Old Pencil Injury.

A 54-year-old female noticed a 2-month history of an enlarging left inferomedial orbital rim mass. The patient remembered a pencil injury at approximately 7 years of age. Her complete ophthalmic examination was otherwise unremarkable. She underwent CT orbital imaging, demonstrating a centrally hyperdense lesion along the left inferomedial orbital rim. There was no involvement of the nasolacrimal duct system. The patient underwent an excisional biopsy. The pathology disclosed noncaseating granulomatous inflammation to particulate black material consistent with graphite.

Intraocular foreign bodies in children: A retrospective case series.

INTRODUCTION: Open globe injuries are a major cause of visual impairment in children, related to the severity of the trauma or secondary to induced amblyopia. Intraocular foreign bodies (IOFB) have been reported in approximately one third of cases of open globe injuries. As clinical presentation and management may differ between adults and children, data is lacking about IOFBs in children under 18years of age. The purpose of this study was to assess the clinical characteristics and visual prognosis of ocular trauma associated with intraocular foreign bodies in children. MATERIALS AND METHODS: This single-center retrospective study included patients under 18years of age treated for ocular trauma with IOFB. Demographic characteristics, complete initial and final ophthalmological examination, imaging data and details of medical and surgical management were collected. RESULTS: Fourteen patients were included (78.6% boys), with a mean age of 10.3years (min 7months-max 17years). In 92.9% of cases, patients were found to have a single IOFB, mostly metallic (71.4%). Posterior segment IOFBs were found in 50% of cases, anterior segment IOFBs in 28.6% and orbital IOFBs in 21.4%. The clinical examination permitted detection of the IOFBs in 50% of cases, while they were visible on CT scan in all cases. The mean initial visual acuity was 20/320, and the mean final visual acuity was 20/125. Endophthalmitis occurred in 2 cases (14%). DISCUSSION: Open globe injuries associated with IOFB are severe and sight-threatening. Localization of the IOFB in the posterior segment has a worse prognosis. CT scan is mandatory, especially in children, as the trauma history is often missing. Retinal detachment and endophthalmitis appear to be the main prognostic factors requiring urgent specialized pediatric ophthalmology management.

[Contribution of technological aids to the extraction of orbital foreign bodies]. / Apport des aides technologiques dans l'extraction des corps étrangers orbitaires.

BACKGROUND: Removal of orbital foreign bodies is a surgical challenge. The purpose of this study is to report our experience in the removal of orbital foreign bodies and to evaluate the usefulness of various technological aids in their removal. MATERIALS AND METHODS: We conducted a single-center retrospective study at Nice University Hospital (France) from January 2017 to December 2023. All patients undergoing surgery for an orbital foreign body during the study period were included. Data recorded included the nature of the orbital foreign body, its size, location, surgical route, outcome (success, partial success, failure), and technological aids used (intraoperative navigation, intraoperative imaging scope, orbital magnet). Concurrently, we designed a dedicated orbital magnet, which was tested in the anatomy laboratory and in two of our patients. RESULTS: Six patients, all young men, were included during the study period. Removal was successful, partially successful, or unsuccessful in one-third of cases, respectively. Failure was associated with orbital foreign bodies located in the intraconal or posterior orbital space. Preoperatively, the use of a "low-artifact" scanner allowed us to better determine the exact size and shape of the orbital foreign body. Intraoperative navigation was not accurate enough, due to the mobility of the orbital bodies within the orbital fat. In our experience, intraoperative scope imaging was more accurate. The use of a dedicated orbital magnet was successfully tested in the anatomy laboratory and allowed the removal of a small orbital foreign body in one of our patients. Intraoperative surgical videos are provided. CONCLUSION: Vegetal orbital foreign bodies must be systematically removed. Removal of non-vegetal orbital foreign bodies should be considered on a case-by-case basis based on their size, best assessed using a "low artifact" scanner, their location, and their intrinsic ferromagnetism. Intraoperative navigation does not appear useful, while intraoperative scope imaging does. A dedicated orbital magnet might be helpful in removing ferromagnetic orbital foreign bodies. However, an orbital magnet may be ineffective in removing intraorbital bullets, since they are made primarily of an alloy of copper and lead.
