If a penetrating eye injury is suspected, what initial action should be taken?

In the case of a suspected penetrating eye injury, the initial action that should be taken is to conduct a rapid field test of visual acuity. This is critical because assessing visual acuity provides immediate information about the functional status of the eye and can help gauge the severity of the injury. Understanding the degree of visual impairment can guide subsequent treatment decisions and urgency.

By determining visual acuity, healthcare providers can identify significant vision loss that may necessitate immediate surgical intervention or specialty referral. Additionally, it allows for a baseline assessment to compare any changes in vision that may occur after treatment.

Other assessments, while important in trauma scenarios, do not take precedence in an eye injury situation. A neurological exam may be relevant if there are signs of brain injury; however, it does not directly address the immediate concerns related to the eye. A traumatic brain injury evaluation questionnaire and gait or balance assessments focus on different aspects of injury evaluation that are less urgent in the context of a penetrating eye injury. Prioritizing visual acuity testing ensures that any potential treatment required to preserve sight is initiated as quickly as possible.
