Cyclophotocoagulation is a laser treatment used to treat glaucoma by reducing the amount of aqueous humor produced in the eye. The procedure targets the ciliary body, which is responsible for producing the fluid that maintains eye pressure.

During the procedure, a laser is applied to the ciliary body, decreasing the production of fluid and lowering intraocular pressure. Cyclophotocoagulation is often recommended for patients with advanced glaucoma who do not respond to medications or other surgical treatments.

This treatment can help preserve vision by controlling intraocular pressure and preventing further damage to the optic nerve.
