What is the initial treatment step for a corneal abrasion?

The initial treatment step for a corneal abrasion focuses on protecting the injured eye while minimizing further damage and discomfort. Covering the eye with an eye shield serves to safeguard it from additional trauma and exposure to irritants or light, which can worsen the pain and hinder healing. The eye shield also helps prevent the patient from unintentionally rubbing the eye, which could exacerbate the abrasion.

While other options may offer some form of relief or support, they aren't typically the immediate first step recommended in clinical practice. Applying ice could lead to further irritation or potential injury to the delicate tissues around the eye. Topical anesthetics might be used later on to relieve pain but should not be the first action taken since they can mask symptoms and potentially delay the diagnosis and treatment of any underlying conditions. Applying pressure to the eye is contraindicated as it could worsen the injury or lead to complications. Thus, an eye shield is the most appropriate first step in the management of a corneal abrasion, prioritizing protection over other interventions.
