A new B-scan ultrasonographic technique for observing ciliary body detachment.

We developed a new B-scan ultrasonographic technique for observing ciliary body detachment. Our technique uses a water-bath immersion method in which a real-time A- and B-mode contact scanner is employed. A ciliary body detachment can be ultrasonographically observed either as a separation of the ciliary body from the sclera or as a swelling of the ciliary body region. This technique makes it possible to diagnose ciliochoroidal detachment accurately while a pathologic change is still localized in the ciliary body region.
