LEIRO, J. et al. La ultrabiomicroscopía en la acomodación. Rev. argent. radiol. [online]. 2014, vol.78, n.1, pp.13-21. ISSN 1852-9992.  http://dx.doi.org/10.7811/rarv78n1a04.

The aim of this study is to understand the biometric behaviour of the ocular structures involved during accommodation. We chose high-frequency ultrasound to study ocular globe anterior segment structures biometric changes in vivo and during accommodation. This technique allows biometric screening, morphological and functional anterior segment, including the posterior lens capsule and changes of the ciliary body that we have failed to study with other techniques. The ultrabiomicroscopy allows visualization during accommodation of the anterior and posterior capsules of the lens, the zonules with insertions in the equatorial capsule and the ciliary body and anterior uvea relative to the lens. The ultrasound images obtained represent the anterior segment structures and their modifi cations in vivo and in real time during accommodation. We studied 75 patients divided into three groups according to age range: Group 1 from 30 to 45 years, Group 2 of 46-60 years, and Group 3 of 61-70 years. The results obtained show how they vary the shape and size of anterior segment structures and relationships with each other, allowing to know their behavior in the loss of accommodation of different age groups studied Ultrasound has proven to be the most appropriate diagnostic method for this research.
