Abstract

Objective: Evaluation of high resolution ultrasound as a diagnostic toolin veterinary ophthalmology. Material and methods: Pathological changesof the anterior segment and the retinal-vitreous-periphery of the eye in125 dogs and 36 cats were imaged using a linear array ultrasound probewith a median frequency of 12 MHz. In addition bulbar, orbital andadnexal changes of the eyes of two guinea pigs and three rabbits werescanned. Histological specimens were taken for comparison when anenucleation was unavoidable. Results: High resolution ultrasound offersthe possibility to image lesions of the anterior and bulbar wall part ofthe eyeball and ocular adnexa in detail. This non-invasive method iswell tolerated. Comparing the utilized method with an ultrasoundbiomicroscope, which is used in human medicine, it was apparent that thelatter is superior in imaging delicate structures of tissue. Overall theprobe used in this study seems to be an appropriate alternative inveterinary use as it has a higher penetration, can be handled moreeasily and has a wider range of applications. Clinical relevance: Highresolution ultrasound was capable to show pathological changes in theeyes of companion animals which have not yet been visualized withstandard ophthalmic ultrasound. Focal points of the examination arelesions of the iris, ciliary body and lens, the diagnosis of glaucoma,trauma, the control of the course of an illness and the review of theoperational outcome of lens extractions and artificial lensimplantations.
