Corneal metallic foreign bodies among Jordanian soldiers

To review the spectrum of metallic foreign bodies among Jordanian soldiers and the efficacy of treatment. A retrospective review was conducted at Prince Rashid Bin Al-Hassan Hospital between August 2011 and March 2012. File and photographs review of 55 patients who attended the ophthalmology clinic and found to have corneal metallic foreign body were included in this study. The following data were extracted and analyzed: age, gender, past ocular history, mechanism and time of injury and whether any eye protective measures were taken for those who were exposed to trauma during work, time to receive treatment, method of corneal foreign body removal, number of foreign bodies, location, depth of foreign body in the cornea, whether the eye was patched or not after removal of corneal foreign body, associated ocular injury, presence of Bell's phenomenon, complications, and duration of absence from work. All patients were males and the age ranged between 17 and 55 years [mean 31.3 years]. Eighty- two percent of eye trauma occurred during work and all of them did not use any protective measure during their work activity. The mid third of the cornea was involved in 39% of patients followed by the paracentral zone in 27%. Corneal foreign bodies were removed by 27 gauge needle in 68% of patients. Eye patch was not used in 48% of patients after removal of foreign body. The most common associated finding was corneal rust in 63% of cases. Absence from work ranged between two to nine days. Corneal foreign bodies are potentially sight threatening that occurs mostly as a result of occupational accidents in male workers who do not comply with the use of eye protection. Educational and safety programs and patient counselling on proper eye protection are essential and must be implemented in the work places to prevent serious eye injuries and work loss.

Trauma ocupacional por corpo estranho corneano superficial / Occupational trauma due to superficial corneal foreign body

OBJETIVO: Avaliar a epidemiologia do trauma ocular por corpo estranho superficial de córnea. MÉTODOS: Os pacientes atendidos no Pronto-Socorro da Universidade Federal de São Paulo entre abril e junho de 2005 que apresentaram corpo estranho superficial de córnea foram entrevistados. Foram avaliados: sexo, idade, profissão, registro legal do emprego, uso, disponibilidade e tipo de equipamentos de proteção utilizados e a fiscalização do seu uso. O conhecimento das complicações deste tipo de acidente também foi avaliado. Os resultados foram analisados com teste do qui quadrado ou teste de Fisher. RESULTADOS: Foram entrevistados 123 pacientes. Apenas 3 eram do sexo feminino e a idade média foi de 36 anos. A maioria destes traumas ocorreu no ambiente de trabalho (86,2 por cento) e 58,4 por cento não possuíam registro legal do emprego. As profissões mais freqüentemente envolvidas foram serralheiro, pedreiro e metalúrgico. Em 79,8 por cento dos locais de trabalho havia equipamentos de proteção e 85,3 por cento dos pacientes eram orientados a usá-los. Em 52,4 por cento dos locais sua utilização era fiscalizada, mas apenas 34,2 por cento usavam no momento do trauma. A utilização foi mais freqüente (p=0,008) e fiscalização mais presente (p=0,0415) entre pacientes com registro legal de emprego. Questionados sobre os riscos, 68,9 por cento dos pacientes tinham consciência das complicações graves deste tipo de acidente. CONCLUSÃO: A maioria dos pacientes tem conhecimento sobre a gravidade do trauma ocular e este tipo de lesão ocorre mesmo em locais com equipamentos de proteção disponíveis, alguns deles até durante o seu uso. Os dados sugerem que enfoque maior da prevenção deve ser na fiscalização e utilização de equipamentos adequados.

PURPOSE: To evaluate the epidemiology of superficial corneal foreign body. METHODS: Patients who were seen at the Emergency Service of the Federal University of São Paulo, from April/05 to June/05, were screened and those with superficial corneal foreign body were interviewed. Data regarding gender, age, occupation, employment status, availability and use of protective devices and supervision of their use were collected. Awareness of the possible complications was also assessed. Results were analyzed using chi-square or Fisher exact test. RESULTS: One hundred twenty-three patients were interviewed. Only 3 patients were female. The mean age was 36 years. Most injuries occurred at the workplace (86.2 percent), and 58.4 percent of the patients did not have a legal employment registration. The occupational activities most frequently reported were construction related activities (44.3 percent) and welding/soldering (11.3 percent). In most workplaces (79.8 percent) protective devices were available and 85.3 percent of the patients were instructed to use them. A safety device was being used during the accident in 34.2 percent of the cases and this was more frequent among patients that had legal employment registry (p=0.008) and among those under supervision (p=0.0415). The majority of the patients (68.9 percent) were aware of the risk of severe complications. CONCLUSIONS: Most patients with superficial corneal foreign body are aware of its severe complications and injuries usually occur in places where safety devices are available and often during their use. Our findings suggest that prevention should focus on supervision and correct use of safety devices.

Cuerpos extraños corneales: eficacia de la oclusión ocular posterior a la extracción / Corneal foreign bodies: usefulness of the ocular oclusion after extraction

Ochenta y cinco pacientes con cuerpos extraños corneales fueron randomizados para recibir parche con unguento de cloranfenicol o colirio de cloranfenicol sin oclusión ocular después de la extracción. La mayoría de los pacientes eran trabajadores jóvenes con evidente riesgo laboral. 55 porciento tuvieron antes otro episodio similar. No hubo diferencia estadística entre ambos grupos. El parche ocular no muestra ventajas en cuanto al dolor y a la tasa de curación del defecto epitelial

Corpo estranho intracristaliniano / Intralenticular foreign body

Os autores apresentaram um estudo de 6 casos de corpo estranho intracristaliniano, evoluindo para opacificaçäo, relaçäo inflamatória e/ou glaucoma agudo. Fizeram revisäo da literatura pertinente, indicaram facectomia (associada a implante de lente intraocular sempre que possível) com retirada do corpo estranho quando metálico) ou em casos que evoluem para catarata. Em casos de cristalino transparente e corpo estranho de natureza inerte, uma conduta expectante pode ser adotada, com controle rotineiro para detecçäo precoce de possíveis complicaçöes. Ressaltaram ainda, que medidas de segurança (óculos de segurança e uso de cinto de segurança teriam evitado todos os casos)
