100:(810 nm wavelength) can be used to perform CPC. Commomon cyclophotocoagulation techniques include transscleral cyclophotocoagulation (TS-CPC), continuous-wave diode cyclophotocoagulation (CW-TSCPC), MicroPulse diode cyclophotocoagulation (MP-TSCPC), endocyclophotocoagulation (ECP) and high-intensity focused ultrasound cyclodestruction (HIFU). Complications are lesser with Trans-scleral diode laser cyclophotocoagulation and Endoscopic diode laser cyclophotocoagulation. 199:
The first surgical procedures to reduce intraocular pressure of the eye, by decreasing production of aqueous humor, by damaging the ciliary body by diathermy, penetrating cyclodiathermy or surgical excision was done in the early twentieth century. Cyclodestruction by diathermy was first performed by

Weve in 1933. In 1949, Berens et al. described cyclo-electrolysis. Cyclocryotherapy was first described by Bietti in 1950. Cyclodestruction by cyclophotocoagulation was first performed by Beckman et al., in 1972, using a ruby laser. ECP was developed by Martin Uram in 1992.
53:. Until the development of safer and less destructive techniques like micropulse diode cyclophotocoagulation and endocyclophotocoagulation, cyclodestructive surgeries were mainly done in refractory glaucoma, or advanced glaucomatous eyes with poor visual prognosis. 178:
and sympathetic ophthalmia are some common complications of cyclodestructive procedures. Since there is risk of inflammation which lead to hypotony and phthisis bulbi, cyclophotocoagulation must be done with extreme caution in

Endocyclophotocoagulation (ECP) or endoscopic cyclophotocoagulation using an endoscope allows direct view of the ciliary processes during surgery. Compared to TS-CPC, tissue disruption is lesser with ECP.
