Assessment of the ciliary body parameters. Trabecular-ciliary process distance (TCPD) is the length of the line extending from the corneal endothelium 500 μm from the scleral spur perpendicularly to the line which passing through the most inner point of the ciliary body and parallel to the iris. Maximum ciliary body thickness (CBTmax) is the distance from the most inner point of the ciliary body to the inner wall of sclera or its extended line. Trabecular-ciliary angle (TCA) is the angle between the posterior corneal surface and the anterior surface of the ciliary body
