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. Types include contusion and lamellar laceration Open globe injury: there is a full thickness injury of the eye wall (cornea and sclera) It includes A) Globe rupture: caused by blunt trauma and is an inside-out injury. B) Globe laceration: a full-thickness wound caused by sharp objects. It includes 1)Penetrating trauma: the globe integrity is disrupted by a full-thickness entry wound and may be associated with prolapse of the internal contents of the eye. Such injuries are often referred to as a Globe fracture or a Globe rupture, although these can be incurred by blunt trauma as well. 2) Perforating trauma: the globe integrity is disrupted in two places due to an entrance and exit wound (through and through injury). This is a quite severe type of eye injury. Other types include Blowout fracture of the orbit is caused by blunt trauma, classically described for fist or ball injury, leading to fracture of the floor or medial wall of the orbit due to sudden increased pressure on the orbital contents. Muscular Entrapment Fracture of the orbital bones can lead to muscular entrapment limiting gaze in one direction. Emergency An emergency must be treated within minutes. This includes chemical burns of both the conjunctiva and cornea. Urgent An urgent case must be treated within hours. This includes penetrating globe injuries; corneal abrasions or corneal foreign bodies; hyphema (must be referred); eyelid lacerations that are deep, involve the lid margin or involve the lacrimal canaliculi; radiant energy burns such as arc eye (welder's burn) or snow blindness; or, rarely, traumatic optic neuropathy. 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
