Allergic conjunctivitis due to drugs or medicaments – http://id.who.int/icd/entity/1881044096

Allergic conjunctivitis due to drugs and medicaments is a toxic reaction may occur following instillation of eye drops, such as topical antiglaucoma agents, mydriatics, or alphaadrenergic agonists commonly used as decongestants in over-the-counter anti-allergy eye drops. Topical antibiotics, eye drops containing herbal extracts, and preservatives, such as benzalkonium chloride, thimerosal, parabens, and ethylenediaminetetraacetic acid (EDTA), may cause either a toxic reaction or a cell-mediated hypersensitivity response. It is characterised by an intense and persistent follicular reaction, associated with mild to intense hyperaemia. The cornea is often involved as a diffuse punctate keratitis.
