[Involutional changes in the human eye accommodative apparatus as evidenced by ultrasound biometry and biomicroscopy].

Abstract

The paper presents the results of studying involutional changes in the accommodative apparatus of the eye in presbyopia by ultrasound biometry and biomicroscopy. Persons aged 40-70 years who had presbyopia and emmetropic refraction and without concomitant eye disease were examined. In addition to routine studies, all the examinees underwent ultrasound biomicroscopy and ultrasound biometry. The age-related lenticular enlargement was established to be accompanied by a considerable reduction in the orbicular space of the posterior chamber of the eye to the extent of its transformation to a slotted space. The presbyopic patients were found to have a significantly diminished tone in the middle and posterior portions of the lenticular ligamentous apparatus to the extent of its sag, with the altered direction of their passage between the crystalline lenticular equator and the ciliary body crown, i. e. from meridional to radial. The revealed significant age-related topographic and anatomic changes in the orbicular portion of the posterior chamber of eye and in ligamentous tone, which are associated with the involutional increase in the size of the crystalline lens point to the great importance of decreasing the working accommodation distance in the development of presbyopia.
