When the ciliary muscle contracts, it opens the trabecular meshwork through increased tension on the scleral spur.

A cyclogoniotomy is a surgical procedure for producing a cyclodialysis, in which the ciliary body is cut from its attachment at the scleral spur under gonioscopic control.

Surgical repair is usually done by 10-0 prolene suture taking the base of iris avulsion and suturing it to the scleral spur and ciliary body junction.
