Cyclodestruction
Surgical procedure that destroys portions of the ciliary body to reduce aqueous humor production and lower intraocular pressure.
Full Definition
Cyclodestruction is a category of glaucoma surgeries that target the ciliary body to reduce aqueous humor production and thereby lower intraocular pressure. These procedures are typically reserved for refractory glaucoma cases where conventional treatments have failed. Methods include cyclocryotherapy (freezing), cyclophotocoagulation (laser), and ultrasonic cycloplasty. The procedure carries risks of hypotony, phthisis bulbi, and visual loss, making careful patient selection crucial.
Usage
Usage note: Often used interchangeably with cyclophotocoagulation, but cyclodestruction is the broader category encompassing all ciliary body destructive procedures.
