Despite the fact that the efficacy of a single session of multispot laser has been demonstrated in the treatment of patients with diabetic retinopathy as compared with four sessions of single-spot laser, the management of panretinal photocoagulation in the different healthcare establishments in France has remained unchanged notably because there is no specific reimbursement for this new treatment protocol.

Although the benefits of reducing the number of sessions and thus the costs associated with the treatment for the patient and the payer seem to be obvious, the medico-economic impact of modifying the treatment strategy thanks to the technological changes must be evaluated to provide deciders with additional information.
