Oftalmo: um sistema especialista para diagnóstico de síndromes oculares.

Abstract

This system reproduces the ophthalmologist's procedure in identifying the syndromes that affect the eyes. The patient is presented with eye signals from which the syndromes including these signals are pre-selected and displayed in descending order of the degree of confidence that the system gives them. There is the option for the doctor to pursue either hypothesis. At this stage, the system investigates the existence of the general organic signs corresponding to the syndrome in question. Based on this set of symptoms the diagnosis is issued. A rule-based expert system employs the backward chaining control scheme, provides explanations of the reasoning process and is implemented in Prolog.
