A chemical eye burn is one of the very few presentations in nursing where the correct action is to begin treatment before completing an assessment.
A chemical eye burn is one of the very few presentations in nursing where the correct action is to begin treatment before completing an assessment. Almost everything else you are taught follows assess-then-intervene. This does not. Every second that a caustic substance remains in contact with the ocular surface, tissue is being destroyed. The injury is not a fixed event that happened before arrival — it is ongoing, and it continues until the chemical is diluted and removed. That single fact reorganizes the entire priority list: irrigation starts immediately, at triage, in the parking lot, at the workplace eyewash station, before a detailed history, before visual acuity testing, and before waiting for a physician assessment. The stakes are proportionate. A mild burn causes days of discomfort and heals without sequelae. A severe alkali burn can destroy the corneal epithelium, penetrate into the anterior chamber, damage the limbal stem cells that make corneal healing possible, and leave a permanently opaque cornea and a blind eye — sometimes within minutes.
