A Missed Periorbital Foreign Body

Trauma involving the eye, orbital and periorbital regions are commonly seen in cases of road traffic accidents, sports injuries and physical assaults, but cases of intraorbital / periorbital foreign bodies are rare. Early presentation, history of trauma, and imaging help in diagnosis. However, sometimes the diagnosis is missed, particularly in cases with late presentation and a vague history of minor trauma and trauma with a non-metallic foreign body. A missed foreign body may present later with infection, repeated inflammation, ptosis, and proptosis and motility defect, further complicating the management.Here, we present a case of missed foreign body during the primary repair of facial injury in a 32-year male with polytrauma sustained in a road traffic accident. Evidence of foreign body was reported in a CT scan head advised for head injury. Re-exploration of wound and removal of foreign body is performed under local anaesthesia.

Etiological causes and epidemiological characteristics of patients with occupational corneal foreign bodies: A prospective study in a hospital-based setting in India

Purpose: Corneal foreign bodies (CFBs) due to occupational exposure have been largely ignored in Indian literature, especially nonmetal workers. Our study looks at a broad range of occupations and settings that contribute to CFB in our local Indian population. The study objective was to determine the occupations, level of education and demographics of patients presenting with CFB acquired during occupational work. Methods: Prospective hospital-based study at a tertiary eye hospital in Gurgaon, Haryana, India, within duration of 9 months. Patients presenting with CFB were asked a set of questions relating to their occupation, level of education, understanding of the potential complications of CFB, and demographics. Results: A total of 83 patients were included in the study. CFB were attributed only to males. 66% of patients were in the age group of 14--29 years. 30% of patients were in the age group 30--44 years and 4% of patients were between 45 and 60 years old. The metal work industry was responsible for 47% of presentations. The construction industry was responsible for 27% of presentations. Electricians and carpenters combined were responsible for 10% of presentations and 17% of presentations occurred in other sectors. Conclusion: CFB occur across a number of occupations in the construction industry, not just metallic workers. Among a population that is generally poorly educated and have nominal understanding of the impact that CFB can have on vision, occupational hazard education is necessary to address this problem.

Effectiveness and prognosis of 23G vitrectomy for perforating ocular trauma caused by metallic foreign bodies / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To summarize the characteristics of ocular perforation caused by metallic foreign body, evaluate the effectiveness and safety of 23G vitrectomy, and analyze the factors that affect the final vision of patients with ocular trauma score. <p>METHODS: Continuous observation and analysis from July 1, 2014 to June 1, 2016, hospitalized in our hospital caused by metallic perforating ocular trauma for 23G vitrectomy in 38 cases(38 eyes). A prospective collection of patient included age, gender, eye, place of occurance of trauma, foreign body size, wound length, foreign body position, initial visual acuity and final visual acuity, macular etc.. The ocular trauma score(OTS)system was used to assess the effectiveness and prognosis of the patients. The follow-up time was over 6mo. <p>RESULTS: There were 38 eyes in 38 patients, including 37 males and 1 females, aged 16y-56y. Ocular trauma mainly occurred in the workplace, 33 cases accounted for 87%, followed by sports venues, 3 cases accounting for 8%. Corrected visual acuity more than 0.1 in eyes with intraocular foreign bodies underwent 23G vitrectomy were 21 cases, accounting for 55%. Preoperative retinal detachment, large foreign body(more than 5.0mm), damage of lens were important factors of poor prognosis. Foreign bodies were located in the vitreous body in 23 cases, accounting for 61%, located in the retina in 15 cases, accounting for 39%. When admitted to hospital, the patients suffered from retinal detachment in 21 cases(55%), endophthalmitis in 7 cases(18%), the size of intraocular foreign bodies(IFOB)was larger than 5.0mm in 7 cases(18%), severe postoperative proliferative vitreoretinopathy(PVR)was in 6 cases(16%), epiretinal membrance of macula in 5 cases(13%). Of the same OTS scores, visual acuity in 6mo was significantly better than preoperative; no matter preoperative vision or postoperative vision in 6mo, the higher the OTS scores, the better the visual acuity. <p>CONCLUSION: The ocular perforation caused by metallic foreign body mostly occurs in young men under 40y, and the main reason is injury in the workplace. No protective measures are adopted. The main factors affecting the final visual acuity are retinal detachment, foreign body greater than 5.0mm and postoperative PVR appearance after the injury, vitrectomy time has little effect. The 23G vitrectomy is safe, reliable and effective in the treatment of ocular penetrating injuries due to metallic foreign bodies. OTS score can be used effectively in patients with ocular perforation caused by metallic foreign bodies and make reasonable and useful postoperative visual acuity prediction.

Clinical analysis of vitrectomy in treatment of 48 eyes with metallic foreign bodies / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To investigate the effect of vitrectomy in treatment of metal intraocular foreign bodies and the factors affecting visual prognosis. METHODS:Fourty seven cases ( 48 eyes ) with foreign bodies from January 2010 to June 2013 in our hospital underwent vitrectomy combined with intraocular foreign body removal were retrospectively analyzed. The changes of visual acuity, the size of foreign body, the complications of preoperative, and the relationship between treatment time and visual acuity were recorded.RESULTS: Totally 46 eyes were successfully removed the complete foreign body, 2 eyes of orbital foreign bodies had not been removed. After 6mo of followed-up, the best corrected visual acuity were all improved in varying degrees (P CONCLUSION:Vitrectomy has obvious advantages in the treatment of metal intraocular foreign bodies. Timely and appropriate vitrectomy is very important to the recovery of visual function.

A Case of Epitheloid Sarcoma on Metal Cutoff Worker / 대한산업의학회지

BACKGROUND: Soft tissue sarcoma is a rare condition with many causative factors. However a soft tissue sarcoma from a metallic foreign body and injury is rare. We report a case of a soft tissue sarcoma caused by a metallic foreign body and injury. CASE: The patient had been worked as a metal cutter for 17 years. While working, his palms were constantly pricked by small metallic splinters, which were generally removed after work. On march 2004, he had palpitated mass on his right palm. On November 2006, a right hand x-ray showed a mass and metallic foreign body at the 1st volar space which was confirmed to be an epitheloid sarcoma. All metallic products of his workplace contained chromium and Nickel. which are known to cause soft tissue sarcomas. A review of the literature revealed foreign-body and injury induced oxidative and nitrative stress to be associated with a developing sarcoma. In addition, Cr and Ni are associated with the development of sarcoma. Therefore it was concluded this case of epitheloid sarcoma was associated with his employment. CONCLUSION: A soft-tissue sarcoma associated with a metal foreign-body and injury is rare and their relationship is difficult understand. If a case of sarcoma is encountered on a metal associated worker, their job association should be considered.

A Case of an Asymptomatic Intralenticular Foreign Body

The purpose of this article is to report a case of an asymptomatic intralenticular metallic foreign body that was retained for 6 months. A 66-year-old male visited our ophthalmology department because of decreased visual acuity in his left eye 6 months after he suffered ocular trauma while mowing. He had not been treated because he did not experience any discomfort. His corrected visual acuity was 0.4. Central corneal opacity, an intralenticular metallic foreign body, and an intact posterior capsule were observed on slit lamp examination. Phacoemulsification with posterior chamber lens implantation and simultaneous removal of the intralenticular foreign body was performed. Seventeen days after the operation, his corrected visual acuity was 1.0, the intraocular lens was well-seated, and there was no intraocular inflammation. In this case report, a patient was found to have an intralenticular metallic foreign body retained for 6 months. During this time he did not experience any ocular dysfunction due to the foreign body. Mowing accidents are common in Korea. Despite the absence of symptoms, patients reporting a history of lawn mowing should be thoroughly examined.
