Analysis of the causes of inflammatory diseases of the vascular tract of the eye

The relationship between cause of uveites and the results of a comprehensive examination of patients are explored. The method of determining the cause of uveites in the examined patient is given, which is based on the theory of fuzzy sets and shows a fuzzy relationship between the results of the survey among chosen patients and reasons of their uveites. The advantage of this method, based on the use of the elements of the theory of fuzzy sets, its ability to build a connection, which is quite difficult to describe analytically with acceptable accuracy. This technique differs from the known ones, because it considers a fairly wide range of causes of uveites, and also makes it possible to determine its cause with sufficient accuracy among a relatively small number of studied patients. The method was applied to a sample of 70 patients with unilateral uveites, for each person the results of a comprehensive clinical and laboratory examination were known and 117 most significant indicators were determined. To determine the relationship between the results of a comprehensive examination of the patient and the cause of uveites, the results of 65 out of 70 patients were used, and the remaining 5 patients were selected to verify the accuracy of determining the causes of uveites. Additional verification of this technique was carried out among six patients with bilateral process. A software package was created to implement the developed methodology.
