THE EXAMINATION OF THE CANINE EYE WITH OPTICAL COHERENCE TOMOGRAPHY

Abstract

Advances in veterinary ophthalmology in recent decades are primarily due to the development of eyeball examination techniques. One of the most advanced, non-invasive, non-contact, and high-resolution techniques is optical coherence tomography (OCT). With this technique, cross-sectional, in vivo images are provided, bringing new insights into the examination of eyeball structures. This technique complements the information provided by the clinical and paraclinical ophthalmic examination. Due to the structural complexity of the eyeball, the imaging examination plays an important role in diagnosing various ocular pathologies and monitoring these pathologies after interventional actions. This study aimed to present and apply this new method of eyeball examination in veterinary medicine for the diagnosis and monitoring of ocular disorders. The objectives of this study were to present the functioning elements, the working method of the tomograph, and the technique of examining the eye in dogs, as well as the analysis and interpretation of the changes found on the image obtained. The biological material used in this study consisted of 18 dogs of different ages and sexes. Eyeball examination was performed using the IVue-100 optical coherence tomography. The results are presented in the form of OCT images of normal and pathological aspects of the eyeball identified in the dogs consulted such as keratoglobus, corneal ulcer, corneal edema, retinal cyst, retinal edema In conclusion, examination of the eyeball with optical coherence tomography (OCT) is a highly accurate technique for observing the physiological or pathological condition of the eyeball.
