Chemical eye injury

Chemical eye injury or chemical burns to the eye are due to either an acidic or alkali substance getting in the eye.[1] Alkalis are typically worse than acidic burns.[2] Mild burns will produce conjunctivitis while more severe burns may cause the cornea to turn white.[2] Litmus paper is an easy way to rule out the diagnosis by verifying that the pH is within the normal range of 7.0—7.2.[1] Large volumes of irrigation is the treatment of choice and should continue until the pH is 6—8.[2] Local anaesthetic eye drops can be used to decrease the pain.[2]
