What is Diode CYC?

Diode CYC is a laser procedure that is used to treat glaucoma. It is generally recommended after other more conservative surgeries like trabeculectomy filter or tube surgeries have failed. It is also used if the vision is already very poor.

  What is Diode CYC?

Diode CYC was a procedure in which the laser was used to destroy a part of the ciliary body, the circumferential structure which lies behind & adjacent to the peripheral iris (colored part of the eye.). As the ciliary body constantly produces aqueous humor, which is the clear liquid which fills the front of the eye, destruction of part of the ciliary body decreases fluid production in the eye & thus decrease intraocular pressure.

 How is Diode CYC done?

After the eye is numbed with a local anesthetic, the laser probe will be positioned over the ciliary body. The laser beam will travels from the sclera (the white part of the eye) to the ciliary body, which is moderately destroyed. The sclera is relatively unharmed as the laser energy is selectively destroys the darker pigmented ciliary body tissue beneath. Laser spots are applied over 270 degrees of the ciliary body. The main goal of the treatment is to leave enough ciliary body alive to produce aqueous liquid but to destroy enough of it to successfully lower the eye pressure. Multiple treatments may be needed.
