Background: Cyclophotocoagulation is the latest development in so-called cyclodestructive procedures. These represent one possibility to reduce the intraocular pressure in glaucoma therapy. Serious complications like pop-effects and hypotonia or phthisis have restricted the clinical use to glaucomatous eyes after failed filtering surgery and insufficient topical therapy even if the contact method and the location of the ciliary body have shown to reduce complications to a certain extent.

Method: Individualisation and optimisation of energy supply are achieved by recording the transmission in real time. The process of coagulation is interrupted by an algorithm or by the surgeon before pop effects can occur.

Results: Pressure reduction is comparable to the established method of cyclophotocoagulation but the complications are less frequent and less severe. The mean energy per spot is reduced by more than the factor of two, thus allowing a more selective coagulation of the target tissue.

Conclusion: Controlled cyclophotocoagulation optimises supply energy and reduces complications after treatment with good pressure reduction.
