Ultrasound elastography in ocular and periocular tissues: A review

Ultrasound elastography has become available in the everyday practice, allowing direct measurement of tissue elasticity with important and expanding clinical applications. Several studies that have evaluated pathological and nonpathological tissues have demonstrated that ultrasound elastography can actually improve diagnostic accuracy of underlying disease process by detecting differences in their elasticity. Ocular and periocular tissues can also be characterized for their elastic properties. In this context, comprehensive review of literature on ultrasound elastography as well as its current applications in Ophthalmology is presented.
