Evaluation of argon laser treatment of diabetic retinopathy and its diffusion in The Netherlands.
Argon laser treatment of diabetic retinopathy (DR) is the best evaluated case in the field of minimally invasive therapy. A well-organized randomized controlled trial was followed by formal cost-analyses and cost-effectiveness analyses. Laser treatment of DR proved to be cost-effective in a situation where there was no satisfactory treatment previously. Subsequently, screening strategies for retinopathy were developed. Systematic screening for DR in diabetic populations would be cost-saving from a societal perspective. The availability of effective and cost-effective therapy and cost-saving screening strategies for DR warrants active policy making to stimulate the implementation of strategies to control retinopathy in diabetic populations. Such strategies would ideally include both guided diffusion of argon lasers and the organization of screening programs. Data from the Netherlands are used to illustrate the diffusion of argon lasers in health care. After a slow start, argon lasers have diffused widely in the Dutch health care system. This development is complemented by recommendations for screening of the European diabetic population, which were issued in 1991. More active cooperation of all parties involved would benefit in preventing blindness from DR.
