chemical burn

Opthalmology A topical eye injury evoked by toxic fluids; untreated CBs can rapidly lead to permanent blindness; alkalines are more dangerous than acids as the high pH causes saponification of membranes with cell disruption and cell death; acids coagulate the superficial proteins, limiting the toxic agent's penetration Agents Ammonia derivatives–cleaning agents, fertilizers, refrigerants, lime products–plaster, mortar Management Irrigate with water, saline or any neutral pH liquid ASAP X ≥ 10 mins

chemical burn 

An injury caused, usually, by alkali (e.g. ammonia, caustic potash, lime, sodium hydroxide) or acid (e.g. hydrochloric, sulphuric). The type and severity of the injury depends on the properties of the chemical and upon which ocular tissue is involved. However, alkali burns are more severe than acid burns because they penetrate the tissues more rapidly and more deeply. In all cases, immediate copious irrigation is crucial, followed by a topicalanaesthetic to relieve pain. Irrigation is continued until repeated measurements of ocular pH reach and retain a normal value. Treatment includes cycloplegics, antibiotics, steroids, ascorbate (only in alkali burns) to restore collagen synthesis, and glaucoma medication may be needed to prevent an increase of intraocular pressure. In some cases, surgery may also be required.
