Comparison of Transcorneal and Transpalpebral Ultrasonographic Measurements of the Eye in Iranian Mix Breed Dog

Objective-The aim of this research was to compare transcorneal and transpalpebral ultrasonography study of the dimensions (ecobiometry) and the ultrasonographic aspect of Iranian mix breed dogs.Design- Experimental studyAnimals- . Ten adult male dogsProcedure- Ten adult male dogs with the mean age ۴±۱.۳۹ years and the mean weight of ۱۶.۷±۳.۶ kg were selected and distributed in two equal groups. Transcorneal and transpalpebral ultrasonographic scanning of left and right eyes of dogs were performed using with a ۱۲ MHZ transducer. The transducer was placed in a longitudinal position (sagittal plane) until optimal B-scan images, were obtained.Results- Means and standard deviations of the intraocular structures of both transcorneal and transpalpebral were as, Anterior chamber depth (۲.۹۹±۰.۲۴۲, ۲.۷۸±۰.۲۸۵ mm), Lens thickness (۶.۶۲±۰.۳۶۴,۷.۰۲±۰.۶۱۲ mm), Vitreous chamber depth (۸.۸۱±۰.۳۵۴, ۸.۷۹±۰.۵۵۲ mm) and Axial globe length (۱۹.۶۰±۰.۴۵۲,۱۹.۵۰±۰.۵۹۲ mm) respectively. No significant differences were observed when comparing left and right eyes of dogs in both methods within the same group and comparing between two groups (p>۰.۰۵).Conclusion and Clinical Relevance- Results of this study can be used as a template in diagnosis of ocular disease and facilitates the use of transpalpebral ultrasonography in the evaluation of ocular structures in ocular disease specially painful conditions.
