Ciliary body ablation is a surgical procedure used to treat glaucoma by reducing the production of aqueous humor, the fluid that fills the eye, which helps control intraocular pressure (IOP). The procedure involves applying laser energy or other methods to the ciliary body, the part of the eye responsible for producing aqueous humor, to reduce fluid production.

By lowering IOP, ciliary body ablation helps to prevent further optic nerve damage and preserve vision in patients with glaucoma. It is typically used in patients with advanced glaucoma or those who do not respond to medications.

Ciliary body ablation is minimally invasive and offers long-term relief from elevated IOP, with faster recovery times compared to traditional glaucoma surgeries.
