Cyclophotocoagulation (CPC) is a laser treatment focused on reducing fluid production in the eye rather than improving drainage, and is typically reserved for advanced or refractory cases of glaucoma.
How is the treatment performed?
The treatment is directed at the 'ciliary body'—the structure inside the eye that produces intraocular fluid. A diode laser penetrates through the white of the eye (sclera) and selectively treats some of the fluid-producing cells, so less fluid is made, and the pressure drops. The procedure is performed under local anesthesia in a small operating room or clinic.
Who is it suitable for?
Traditionally, this treatment was performed primarily on eyes with very severe glaucoma that did not respond to surgeries. Today, with the development of Micropulse CPC laser technology, the treatment has become much gentler with a vastly improved safety profile, allowing it to be offered in earlier stages of the disease as an alternative to invasive surgery.
