Most of the orbital foreign bodies enter the orbit from the front between the eye and the orbital rim. The eye can be left without direct injury and most retain vision, while a few foreign bodies that fly at high speed can penetrate the eye and remain deep in the orbit. Injury-causing objects are mainly metallic foreign bodies such as lead bullets and steel, but a few are non-metallic such as glass and plants. Prevention of orbital foreign bodies: Because of the serious consequences of ocular trauma, it is sometimes difficult to restore vision even with timely treatment. Therefore, the prevention of ocular trauma should be strengthened. 1.Strengthen publicity and education Regular publicity and education in factories to make workers understand the hazards of ocular trauma and the significance of preventing ocular trauma, and understand common sense of prevention. Publicity and education should also be carried out in rural areas when harvesting, applying pesticides and capital construction. 2.Strictly implement the safety system Firstly, develop the safety system and operation procedures, and regularly check the implementation and inspect the equipment. 3.Improve labor conditions Next to the equipment where accidents may occur, protective facilities should be set up, and attention should be paid to lighting, ventilation, dust-absorbing devices, etc. Personal protective gear should not be neglected either. 4.Training of grassroots health personnel to master the prevention and first aid measures for various eye trauma. 5.Ban or safe firecrackers Strengthening social security is also an important measure to reduce ocular trauma.
