Using of optical coherence tomography in diagnosis of lesions caused by gas-based self-defense weapon

Abstract

The article presents the experience of using optical coherence tomography in diagnostics of lesions in the anterior segment of a rabbit eye caused by inducing an experimentally modeled trauma resulting from exposure to a gas-based selfdefense weapon. Gas-based weaponry is presently used tn special forms by law enforcement agencies for the purpose of not control as well as for self-defense. The law enforcement structures and means of self-defense have been provided in the last years by modern gas-based weapons: oleoresin capsaicin and its synthetic analogues, used alone or in combination with ort ochlorbenziloidenmalonodinitrile. Diagnostics and treatment of eye trauma have largely been neglected in Russian medical literature and their criteria have not been sufficiently defined. The optical coherence tomography data illustrate changes in the cornea structure at various times after the trauma incident and in relation to the applied therapeutic treatment. These structural changes have been confirmed by pathomorphology studies. It has been found that optical coherence tomography is a high-sensitivity method of study of the cornea damaged by the gas-based weaponry, which allows to track dynamically, the development of the trauma and the results on various media (electronic, paper), letting to perform a retrospective analysis as well. It has been concluded, as a result of this study, that applications of optical coherence tomography for diagnostics and evaluation of treatment pertaining to experimental animals are acceptable and effective.
