Management of chemical eye burns

Chemical eye burns happen when the eye comes in direct contact with a solid, liquid or gaseous chemical. The severity of the burn will depend on the type of chemical and the amount that enters the eyes. Chemical burns have 3 categories based on the acidic or alkaline level which is measured in pH. The pH scale ranges from 0-14 and indicates the acidity of the chemical.

Categories

  • Alkali burns are usually caused by high pH chemicals and highly dangerous. It can penetrate the eye and cause damage to the vital inner components. They can lead to the formation of cataracts and glaucoma and sometimes cause vision loss or blindness. The common alkali substances can be found in cleaning products such as drain cleaners, oven cleaners, plaster, cement and fertilizers.
  • Acid burns has low pH but still dangerous. The burns cannot penetrate the eye but can cause injury to the cornea and loss of vision. Common acids include sulphuric acid, hydrochloric acid, nitric acid and acetic acid. These chemicals can be found in glass polish, vinegar, nail polish remover and car battery.
  • Irritations or burns are neutral in pH. Common household irritants include household detergents and pepper spray.
