Chemical Eye Injury

Sources: • Alkali (worst — liquefactive necrosis, deep penetration): cleaning products, ammonia, concrete, lime, drain cleaners. • Acid (coagulative necrosis, less deep): toilet bowl cleaner, battery acid, hydrofluoric acid (worst — see HF pathway). • Solvents, gases. Features: severe pain, photophobia, ↓ vision, lacrimation, blepharospasm, conjunctival redness, corneal cloudiness, limbal blanching (ischaemia — predicts severity). #1 INTERVENTION: IRRIGATION — START NOW, ASK QUESTIONS LATER.
