Purpose:
To investigate the ultrasound biomicroscopic (ultrasound biomicroscopy, UBM) characteristics of uveitis and its clinical application.
Methods:
Twenty cases (36 eyes) diagnosed as uveitis were examined by UBM in anterior segments of the eyes, including anterior chamber, anterior chamber angle, posterior chamber, ciliary body and vitreous base. And the images were analyzed.
Results:
Different images were shown in the UBM of 20 cases, including dot-like high reflection in anterior chamber; completely or partly anterior synechia of iris, angle closure; posterior synechia of iris, high bulge of iris and pupil atresia; mass or flake-like resonance in posterior chamber; ciliary body edema and "snowbank" reflection in pars plana; dot or thread-like high reflection on vitreous base.
Conclusions:
UBM examinations can demonstrate various pathologic changes of uveitis in anterior segment of the eye and provide objective evidence for the clinical diagnosis of uveitis.
