Использование ультразвуковой биомикроскопии при различных стадиях ретинопатии недоношенных

[摘要] Purpose.To study anatomical-topographical features of the anterior segment of the eye at different stages of retinopathy of prematurity (ROP) based on the ultrasound biomicroscopy, to determine criteria of disease progression and to assess the possibilities to use the obtained data for an optimization of the laser and surgical treatment. Material and methods . Ultrasound biomicroscopy (UBM) was performed in 217 eyes of 123 premature babies in the gestation terms of 26-34 weeks, of them: at the ROP stage I – 44 eyes (20%) 25 newborn children, at the stage II – 35 eyes (16%) 21 newborn babies, at the stage III – 42 eyes (19%) 24 newborns, at the stage IV – 49 eyes (22.5%) 28 newborns, at the stage V – 47 eyes (21.7%) 25 newborns. the control group consisted of 20 premature babies (40 eyes) without ROP signs and other eye diseases aged from 1 to 4 months. Results . The conducted research allowed to calculate angular and linear parameters for premature babies with no ROP signs, and also for babies of the ac tive ROP stages III, IV and V. Specificity of spatial correlations in structures of the anterior segment of the eye was defined for children with different ROP stages. Сonclusion.Specific structural violations were revealed by the UBM method in the area of the far retinal periphery, as well as in the postzonular and retrolental spaces in case of the ROP stages IV and V. The use of ultrasound biomicroscopy data in the ROP case allows to optimize the parameters of laser irradiation in the ROP stages III and II with adverse types of ROP course, to clarify the volume of surgical intervention at ROP stage IV, identify the optimum area of an operational access at ROP stage V.
