Abstract
Ultrasound can provide diagnostic information to guide the management of glaucoma. The utility of echography is especially evident in cases where direct visualization or optical imaging techniques are precluded by normal anatomy or media opacities. Conventional ultrasound can overcome opacities such as dense cataracts or corneal scars to produce images of the posterior segment and provide evidence of glaucoma etiologies. Ultrasound biomicroscopy (UBM) can acquire high-resolution images of the anterior segment and of structures obscured by and posterior to the iris that may glaucoma. Recent developments in ultrasound technology have also enabled the measurement of biomechanical properties of ocular tissues to establish a relationship between ultrasound elastography and glaucoma. Despite the development of high-resolution optical imaging techniques, ultrasound remains a useful clinical tool with an evolving scope in the management of glaucoma.
