Abstract:
ObjectiveTo investigate the value of ultrasound on the diagnosis of posterior dislocation of the lens. MethodsThe eyes of 38 patients with different kinds of posterior dislocation of the lens were examined by color Doppler ultrasound to understand location, forms, and echogram of the lens and relation with their environmental tissues. ResultsOf 38 cases, 13 cases with complete posterior dislocation of the lens, 3 cases with posterior dislocation of intraocular lens, and 22 cases with incomplete posterior dislocation of the lens were proved. Also, 4 cases with vitreous hemorrhage, 13 cases with vitreous opacity and fibrous membrane, 15 cases with posterior detachment of the vitreous, 3 cases with retinal detachment were found. In addition, 33 cases underwent vitrectomy combining lensectomy or removal of the lens, among them, diagnostic ratio of ultrasound was 100%. ConclusionsHigh practical value is shown in posterior dislocation of the lens by ultrasound as one of the important methods on the diagnosis. At the same time, it provides valuable references for choosing surgical methods of posterior dislocation of the lens.
