Expert System for Risk Analysis in Sight-threatening
Diabetic Retinopathy using MatSOAP
Control of glucose, BP and cholesterol can slow progression of sight threatening retinopathy (STDR). Here we define the retinopathy as as moderate pre-proliferative retinopathy or greater and/or ciricinate maculopathy or exudates within one disc diameter of centre of the fovea), ungradeable images or other significant eye disease in either eye and consequently attending for slit-lamp biomicroscopy.
The Expert System for Risk Analysis in Sight-threatening Diabetic Retinopathy is constructed from 500 patient records selected arbitrarily from the St Paul's Eye Unit Diabetic Database. The likelihood (or 'risk') of developing STDR is estimated using a simple generalized linear network (GLM) from a combination of risk factors viz:
