Toxic carriers in @entity5793 may cause XXXX .

We describe four @entity1 who developed @entity2687 after an exposure to a pepper spray containing toxic carriers. Two of these @entity1 were exposed to a pepper gas containing 5% oleoresin capsicum (OC) as an irritant and 92% @entity4966 or unknown amount of @entity1044 as a carrier. One @entity1 was exposed to a mock (containing 92% @entity4966 as a carrier) training pepper gas without OC. The fourth @entity1 was exposed to an unidentified Russian pepper gas spray. Two of the @entity1 were examined by in vivo confocal microscopy to demonstrate the depth and quality of the stromal damage. To test the @entity137 of the commercial tear spray, it was analyzed and test sprayed on a soft contact lens and into a plastic cup. Visual acuity was measured and the eyes were examined with a slit-lamp up to 5 months. Physical damage to a soft contact lens was visually acquired. All @entity1 showed a long-lasting, deep corneal and conjuctival erosion, which resolved partly with medical therapy during the following weeks/months. Confocal microscopy revealed @entity16 , and keratocyte activation reaching two-thirds of stroma for one @entity1 . The spray caused serious damage to both the soft contact lens and the plastic cup. The safety of the commercially available @entity5793 should be assessed before marketing, and a list of acceptable ingredients created. The sprays should also have instructions on the use of the compound as well as on the first aid measures after the exposure. Solvents known to be toxic should not be used.
