What indicates the need for referral in cases of corneal abrasion?

In cases of corneal abrasion, persistent blurred vision is a significant indicator that prompts the need for referral to an eye care specialist. Blurred vision often suggests that there may be complications, such as a deeper injury to the cornea or an associated condition that could impair vision permanently if not properly addressed.

The presence of blurred vision indicates that the abrasion may not be healing as expected or that other detrimental factors are at play that could worsen the eye condition. Referral in such scenarios helps ensure that further evaluation and potential treatment are provided, which may include more specialized interventions such as the application of therapeutic lenses or surgical approaches, depending on the severity of the injury.

In contrast, pain relief after medication, normal visual acuity, and intermittent tearing do not necessarily indicate the need for urgent referral. Pain management is a normal part of care, and normal visual acuity suggests that the injury may be minor. Intermittent tearing can occur naturally with corneal abrasions and may not reflect a critical need for specialist intervention unless accompanied by other concerning symptoms.
