ULTRASOUND BIOMICROSCOPY OF THE RETINAL PERIPHERY IN CATARACT PATIENTS WITH HIGH MYOPIA
High myopia often leads to the development of chorioretinal dystrophies, which, in their turn, determine the high risk of retinal detachment. The opaque optical medium impede the visualization of the extreme fundus periphery when using the standard methods of examination. Ultrasound biomicroscopy (UBM) of retinal periphery is feasible at different degrees of lens opacity. Aim of the study – to investigate the status of the peripheral vitreoretinal interface and to assess the dynamics of its alteration by ultrasound biomicroscopy (UBM) in patients with high myopia before and after cataract phacoemulsification. Material and methods. 74 patients (96 eyes) with high myopia and cataract were examined. Age was 65.04 ± 1.16 years, spherical equivalent refraction – 13.63 ± 0.59 D, anterior posterior ocular axis length – 28.17 ± 0.23 mm. The examination of retinal periphery by means of ultrasound biomicroscopy was performed using the device UD-6000, Tomey (Japan) before cataract phacoemulsification, within the first days after surgery, in 1 month, in 6 month. Results. UBM allowed diagnosing the acoustic alterations in the retinal periphery in 85 % of cases (82 eyes) in high myopia and cataract. Normal acoustic clinical picture of the retinal periphery was revealed in 15 % of cases (14 eyes). The acoustic alterations of the vitreous body adjoining retinal periphery was detected in 39 % of cases (37 eyes). The alterations of the retinal periphery and adjoined vitreous body, detected by UBM are progressive. The statistically significant alterations were noted by the 6th month of follow-up. Conclusion. The information about the status of retinal periphery and adjoining vitreous body, obtained with UBM, enhances the diagnostic capabilities in high myopia and lens opacity, helps in determining the course of patient’s management and preventing retinal complications in time.
