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 study animals- ten adult male dogs procedure- ten adult male dogs with the mean age 4±1.39 years and the mean weight of 16.7±2.31 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 12 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 (2.99±0.242, 2.78±0.285 mm), lens thickness (6.62±0.364,7.02±0.612 mm), vitreous chamber depth (8.81±0.354, 8.79±0.552 mm) and axial globe length (19.60±0.452,19.50±0.592 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>0.05). 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 especially painful conditions.
