[Combined ultrasound study in the prediction of the results of surgical treatment for persistent hyperplastic primary vitreous body in children].

In children with persistent hyperplastic primary vitreous body (PHPVB) concurrent with unilateral congenial cataracts (UCC), combined ultrasound study used to examine blood supply to and hemodynamics of the hyaloid system--a fibrovascular band. To determine the prognosis of a surgical intervention in the mode of color and energy Doppler mapping in the persistent band, retrolenticular membrane, the authors studied whether they had functioning vessels and linear blood flow velocity in different degrees of PHPVB. Based on the results of combined ultrasound study, the authors defined indications for and contraindications to surgical treatment of UCC concurrent with PHPVB in order to prevent hemorrhagic complications (hyphema, hemophthalmos, hyaloid vascular bleeding), as well as the optimal time of surgical treatment.
