| Soldiers blinded by mustard gas
in World War I.
Mustard gas is an alkylating agent. Contact with the conjunctiva and cornea causes pain, photophobia, tearing, blepharospasm, blurred vision, chemical conjunctivitis, corneal damage, conjunctival necrosis, corneal opacification, cornea pannus, secondary glaucoma and chronic keratitis. Superficial eyelid damage may lead to chronic ectropion, trichiasis, and symblepharon formation. |
