Road traffic accidents (RTAs) with head and facial trauma may also have an eye injury - these are usually severe in nature with multiple lacerations, shards of glasses embedded in tissues, orbital fractures, severe hematoma and penetrating open-globe injuries with prolapse of eye contents. Other causes of intraocular trauma may arise from workplace tools or even common household implements, including bottle-caps suddenly propelling at great force.About 5.3 million cases of foreign bodies in the eyes occurred in 2013. Presentation
Complications
Multiple complications are known to occur following eye injury: corneal scarring, hyphema, iridodialysis, post-traumatic glaucoma, uveitis cataract, vitreous hemorrhage and retinal detachment. The complications risk is high with retinal tears, penetrating injuries and severe blunt trauma. Diagnosis
The goal of investigation is the assessment of the severity of the ocular injury with an eye to implementing a management plan as soon as is required. The usual eye examination should be attempted, and may require a topical anesthetic in order to be tolerable. Many topical agents cause burning upon instillation. Proxymetacaine has been found to have the best tolerance.Depending on the medical history and preliminary examination, the primary care physician should designate the eye injury as a true emergency, urgent or semi-urgent. Classification
Based on the injury to the eyewall (outer fibrous coat of the eye consisting of cornea and sclera)

Closed globe injury: the eye globe is intact, but the seven rings of the eye have been classically described as affected by blunt trauma.
Semi-urgent
Semi-urgent cases must be managed within 1–2 days. They include orbital fractures and subconjunctival hemorrhages. Management
Irrigation
The first line of management for chemical injuries is usually copious irrigation of the eye with an isotonic saline or sterile water. In the cases of chemical burns, one should not try to buffer the solution, but instead dilute it with copious flushing. Patching
Depending on the type of ocular injury, either a pressure patch or shield patch should be applied. Up until circa 1987, pressure patches were the preferred method of treatment for corneal abrasions in non-contact lens wearers;  multiple controlled studies conducted by accredited organizations such as the American Academy of Ophthalmology have shown that pressure patching is of little or no value in healing corneal abrasions and is actually detrimental to healing in some cases. A Cochrane review found that patching simple corneal abrasions may not improve healing or reduce pain. Pressure patching should never be used on an individual presenting with a corneal abrasion who has a history of contact lens wear. In this circumstance, a virulent infection caused by the bacterium Pseudomonas aeruginosa is at a clearly delineated increased risk for occurrence. These infections can cause blindness within 24 – 48 hours and there is a possibility that the infection can move into the peri-orbital socket, resulting in the need for evisceration of the eyeball. In rare cases, the infection can enter the brain and cause death to the patient.
