ABSTRACT
Background:
With ultrasound biomicroscopy (UBM), radial scans are taken by using a typical ciliary process, to show the details of the iridocorneal angle, the anterior surface of the ciliary body, and its relation to the posterior iris. Appositional closure represents potentially reversible contact between the peripheral iris and trabecular meshwork. The appositional closure can further be classified according to the configuration of iridotrabecular contact (ITC). UBM can be performed in dark and light conditions, which has been shown to be useful for detecting changes in iridocorneal angle configuration associated with dark and light.Purpose:
To image ITC configuration in appositional angle closure and also image iridocorneal angle in dark and bright light room illumination. Synopsis UBM demonstrates two types of ITC configuration in appositional closure which are, B?type and S?type. It can also demonstrate the presence of sinus of Mapstone in S?type of ITC. Highlights UBM allows imaging of dynamic changes in the iris and shows that the degree of appositional angle closure is a dynamic process that can change rapidly depending on the lighting conditions.
