[Controlled cyclophotocoagulation (COCO) : What needs to be considered?].

The major disadvantage of modern laser cyclocoagulation is the low predictability of therapeutic success in individual cases. Unwanted damage and complications of controlled cyclophotocoagulation (COCO) are very unlikely, particularly because of the high selectivity of photoabsorption. Therefore, these interventions can and must be repeated if the intraocular pressure reduction is insufficient after the initial treatment or if the pressure increases again later. The indications and protocol for repeat interventions are the same as for the initial intervention.
