Fig. 1From: Classifications of anterior segment structure of congenital corneal opacity in infants and toddlers by ultrasound biomicroscopy and slit-lamp microscopic photographs: an observational studyUltrasound biomicroscopic images of different ultrasound biomicroscopic classifications. (a) Only an opaque cornea was shown in ultrasound biomicroscopic images. (b) Ultrasound biomicroscopic images showed opaque cornea and central anterior synechia. (c) Ultrasound biomicroscopic images showed an opaque cornea and peripheral iridocorneal synechia, combined with angle closure ranging less than or equal to 180 degrees. (d) Ultrasound biomicroscopic images showed an opaque cornea and peripheral iridocorneal synechia, combined with angle closure greater than 180 degrees. (e) The eyes classified as U4 are coupled with or without angle closure, and ultrasound biomicroscopic images revealed an opaque cornea with iris and lens anomalyBack to article page
