“…However, high-resolution ocular ultrasound presents higher sensitivity and sensibility (Hendrix, 2013). Ultrasound biomicroscopy has been reported as effective in the diagnosis, size evaluation and localisation of ciliary body cysts in humans (Maraone et al, 2014) and more effective than standard ocular ultrasonography (7 to 12 MHz) in the detection of canine uveal cysts (Taylor et al, 2015); thus, it may consist the method-of-choice for early diagnosis of cyst formation or detection of small-size cysts on the contralateral eye, especially in human patients that usually present smaller-size cysts [0.6547 ± 0.2319 mm (Wang and Yao, 2012), 0.81 ± 0.35 mm (Maraone et al, 2014)]. However, its use may be impractical for animal patients, as heavy sedation or general anaesthesia may be required.…”
