CPT® Code 66711

The procedure described by CPT® Code 66711 involves the destruction of the ciliary body through a technique known as endoscopic cyclophotocoagulation (ECP). The ciliary body is a crucial structure located just behind the iris of the eye, responsible for producing aqueous humor, the clear fluid that fills the anterior chamber of the eye. This structure also plays a vital role in the accommodation process, which allows the eye to focus on objects at varying distances by changing the shape of the crystalline lens. The primary indication for performing ciliary body destruction is to manage glaucoma, particularly in cases where the condition has not responded adequately to medication or less invasive surgical interventions aimed at improving aqueous outflow. By partially destroying the ciliary body, the inflow of aqueous humor into the anterior chamber is reduced, leading to a decrease in intraocular pressure, which is essential for preventing damage to the optic nerve and preserving vision. The endoscopic approach utilized in this procedure allows for a more precise targeting of the ciliary processes while minimizing damage to surrounding tissues, making it suitable for patients with better visual potential. The procedure is performed under local anesthesia, ensuring patient comfort while maintaining the necessary level of awareness during the operation.
