What is the first step in the assessment of a possible corneal abrasion?

Measuring visual acuity is the first step in the assessment of a possible corneal abrasion because it establishes a baseline understanding of the patient's vision and helps to determine the severity of the injury. Visual acuity testing is crucial in eye examinations as it provides vital information regarding the function of the eye and any potential effects on vision from the abrasion.

By assessing how well the patient can see, the provider can decide on the urgency of further treatment or interventions. Integrating visual acuity assessment early in the evaluation process allows for appropriate follow-up measures, including referrals or additional diagnostics if there is significant visual impairment.

Other steps, such as checking for pupillary reaction, irrigating the eye, or performing a fundoscopic exam, are important aspects of a comprehensive eye assessment but are secondary to establishing visual acuity. These subsequent evaluations may aid in diagnosing the nature and extent of any injury or condition present, but they do not provide initial insights into visual function.
