Ultrasonic Characterization of Corneal Thickness and Axial Length of Pig Eyeball Caracterización Ultrasónica del Grosor Corneal y la Longitud Axial del Globo Ocular Porcino

Ultrasound is a tool frequently used to diagnose ocular pathologies due to non-invasive and nonionizing features. Pachymetry and echography are standard techniques used to determine ocular anomalies related to different diseases. However, research in this field is even so extensive, mainly focused on high resolution and low-cost diagnosis. In this work, the initial stage of our research project, which is oriented to detection of parameters related to ocular pathologies, is described. In such stage, the ultrasonic characterization of two measures related to ocular size of healthy pig: corneal thickness and axial length, that will be used in detection of ocular diseases, was performed. Two transducers, with different central frequency, were used for this characterization. Obtained results (1016±43μm and 995±121μm for the corneal thickness; and 19.77±0.49 mm and 20.40±0.60 mm for the axial length) agree with range of values reported in the literature (833μm - 1013μm for the corneal thickness and 23mm - 24mm for the axial length).
