Eye injuries are a major and underrecognized cause of disabling ocular morbidity that especially affects the young. Ocular traumas represent a complex and heterogeneous entity showing high variability both in terms of etiology and clinical expression [Table 1]. The most affected patient categories are children and workers; which has important implications in terms of long-term prognosis, morbidity as well as economic cost.[1],[2] Globally, more than 500,000 blinding injuries occur every year. Approximately 1.6 million people are blind owing to ocular trauma, 2.3 million are bilaterally visually impaired, and 19 million have a unilateral visual loss.[3],[4],[5] Developing countries often lack adequate infrastructure for persons with eye injuries to reach a primary care center, when one exists, and the lack of awareness of preventive measures and/or immediate actions increases the risk for complications and consequent visual disability. In most instances, emergency care units are not able to deal with such events, thus making it necessary to refer the patient to specialized ophthalmic facilities. A multidisciplinary ophthalmic intervention may be required, making management and treatment of these cases complex and difficult.[1],[2],[3],[4],[5]

When confronted with ocular trauma, the practitioner should firstly take a comprehensive history [Table 2] of the events leading to, and timeline surrounding, the injury. Second, on examination of the patient, an ocular assessment as outlined should be performed after the general examination.

The management of an injured eye requires meticulous history collection, measurement of visual acuity, and detection of relative pupillary defects, a careful inspection of the eyes, using anesthetic if needed. Proper documentation of initial vision is required medicolegally and is also a prognostic indicator. If letters cannot be read, the ability to count fingers, detect hand movements, and to perceive light are recorded in that order as CF (Counting Fingers), HM (Hand Motions), LP (Light Perception) and NLP (No Light Perception). An ultrasound is useful in evaluating posterior structures and the presence of an intraocular foreign body. An assessment of the trauma provides primarily the score calculation and analysis of wounds requiring immediate suturing to avoid any superinfection.

Birmingham Eye Trauma Terminology (BETT) is an internationally standardized terminology allowing a fine description of eye injuries. Following BETT, it is possible to describe clinical features of given eye trauma. BETT allows unambiguous description and helps in the referral of cases with clarity in management requirement between centers. Once the clinical and instrumental evaluation of the ocular damage is completed, an important step is to quantify visual prognosis.[6],[7],[8] The Ocular Trauma Score (OTS) is a set of six factors, which provide a prediction of the patient's visual acuity recovery at 6-month follow-up. OTS score is a reliable predictor of visual prognosis when assessing an open globe injury, but a deeper investigation is required when other serious conditions, such as endophthalmitis and retinal detachment, occur in the trauma patient, OTS provides a practical guideline to referral centers for counseling patients regarding the gravity of injury and expectation of visual prognosis.[6],[9],[10]


  Triaging Ocular Emergencies Top


Triage is the process of determining the priorities for action in an emergency and of establishing the order in which to carry out acts of medical assistance. This process is critical to appropriate care and treatment of patients who experience ocular emergencies and could mean the difference between adequate vision and potential blindness.[11],[12],[13],[14]


  Level of Urgency Top


First, establish the level of urgency. Individual eye physicians also may have a definition of what they perceive the levels of urgency are for specific emergencies which are not an acceptable practice with regard to the specific emergencies. It is important to have the eye physician develop triage guidelines that provide the appropriate time frame for a specific medical emergency. The level of urgency helps to define the time frame for specialized intervention to maximize vision potential [Table 3].

  Nonpenetrating/contusion Injuries Top


  • Mechanism: Sudden increase in the orbital pressure as a result of a striking object[15],[16]
  • Evaluation: An orbital blow-out fracture and optic neuropathy to be ruled out even if white eyed. Periocular ecchymosis and edema, deterioration in vision, numbness of the cheek, side of the nose and upper lip, and diplopia (double vision)
  • Level of urgency: Urgent/(Suspected with withe eyed blow out): Immediate.



  Chemical Splashes and Burns Top


  • Mechanism: Usually caused by either alkali (having a pH of 7.1 or greater) or acids (having a pH <7.0). Chemical burns also are caused by thermal or ultraviolet exposure. Alkalines are usually more damaging because they can permeate the eye rapidly. Common alkalines are ammonia (fertilizer, refrigerants, and household cleaners), lye (drain and oven cleaners), lime (plaster and concrete), and fireworks (sparklers and flares)[17],[18],[19]
  • Evaluation: As soon as the patient arrives at the clinic, the eye should be irrigated again (after checking with the physician) and its pH level checked until the reading is 7.0 (neutral)
  • Special instructions: Ask the patient to bring the chemical agent or provide a label identifying the contents of the source of the splash if possible
  • Level of urgency: Semi-urgent, if with limbal ischemia/melt: Urgent



  Corneal Abrasion Top


  • Mechanism: Depends on the time of onset. If pain was noted at the time of waking up, with foreign body sensation and redness, it is possible the patient would have scratched themselves during sleep. Abrasions can also be caused by contact lens over wear or recurrent erosion syndrome. Minor abrasions may heal on their own within two to 4 h; many patients experience significant pain, depending on the severity and location of the abrasion, and will request immediate care[20],[21]
  • Evaluation: Include a slit-lamp evaluation using fluorescein dye to determine if an epithelial defect is present, and if so, to what extent. Make certain that there is no foreign-body visible in the cornea or fornices. Primary concern is to prevent infection and to ease pain while making certain that the abrasion heals appropriately. Patients should be seen within 24 h of their injury
  • Special instructions: Instruct the patient not to remove foreign body or treat the eye with any drops
  • Level of urgency: Semi-urgent to urgent (with infiltration).



  Blunt Trauma Top


  • Mechanism: Sports-related injuries, assault/fights, job-related injuries, automobile accidents, projectiles, and explosions
  • Effect: Blunt trauma often causes simultaneous injuries to multiple parts of the eye
  • Ecchymosis (bruising) of the eyelids, hyphemia, angle recession, retinal tears, a retinal detachment, and ruptured globe.[9],[22]
  • Evaluation: Comprehensive eye examination, including extraocular muscle evaluation, pupil testing, intraocular pressure, and dilation
  • Special instructions: Instruct not to put pressure on the eye, not to patch the eye, and not to manipulate the eye in any way before the ophthalmologist evaluation
  • Referral level of urgency: Urgent (nonopen globe)/immediate (open globe).



  Penetrating Trauma Top


  • Mechanism: Penetrating injuries may include fishhooks, nails, sticks, and pencils[21],[22]
  • Primary level evaluation: Important to stabilize the patient and the object immediately, taking care to avoid putting any pressure on the foreign object. If the eye can be close, a shield can be applied and bandaged. Avoid the use of topical medications with preservative. Only use a preservative-free antibiotic or ointments under patch
  • Special instructions: Make sure to provide clear instructions to leave the object in the eye!
  • Level of urgency: Immediate


In conclusion, triaging trauma for a referral depends on the level of facility at which initial management in sought. The conventional BETT system classification, though robust, does not include a comprehensive spectrum of ophthalmic trauma. It fails to describe nonmechanical globe trauma, which makes up a significant proportion of eye injuries. A tertiary care ophthalmic facility is required in all cases of trauma with adnexal traumas and severe chemical and blunt trauma and is imperative for all open globe injuries. Referrals can me made using predesigned format [Table 4] covering nature/mechanism of injury and level of triage to be given at the higher center avoiding initial delay in the referral centers.
