Cyclodialysis
Cyclodialysis, the separation of the ciliary body from its insertion at the scleral spur, may occur as a result of trauma or surgical manipulation of intraocular tissue (Fig 10-4). Gonioscopic examination shows a deep-angle recess with a gap between the sclera and the ciliary body (Fig 10-5). Repair of a cyclodialysis cleft is often indicated if hypotony results. Closure may be achieved with laser photocoagulation at the site of cyclodialysis; if this is ineffective, it may be necessary to reattach the ciliary body with sutures (Video 10-5). A significant and sudden elevation in IOP may occur as a result of cyclodialysis closure. For further discussion of cyclodialysis, see BCSC Section 10, Glaucoma.
