A discrete event simulation describes the screening and natural history of eye disease in patients with diabetes, using the POST simulation software. Discrete event simulation, unlike other modeling techniques, can show the interaction between screening and the two main diabetic eye disease processes. Results show that there is a tradeoff between screening frequency, screening sensitivity and patient compliance. The extent to which screening is cost effective is not clear cut. We have little data on the cost of blindness and different views on the appropriate quality-of-life values to assume. The model can be extended to evaluate prevention and treatment for all the complications of diabetes.
