This laser procedure aims to decrease the aqueous production by treating part of the ciliary body epithelium (structure located behind the iris responsible to produce aqueous humor).
In most of the cases, this procedure is reserved for eyes with end stage glaucoma, that have elevated IOP despite conventional medical and/or multiple surgical treatment. It is also performed in painful blind eyes. This restricted indication is due to the possibility of hypotony (low eye pressure) and globe atrophy.
New approaches of this technique are under evaluation to be performed in eyes with less severe stages of glaucoma, particularly those using endoscopic techniques (endocyclophotocoagulation) or new laser devices (micropulse).
