A computerised diagnostic index for medical and neuro-ophthalmology

We have developed a classification that meets the requirements of the Medical Eye Unit and computerised it. The classification uses three categories: anatomical site of lesion, pathological process, and clinical diagnosis. Each patient is identified by standard data and up to three entries in each of anatomical localisation, pathological diagnosis, and clinical diagnosis. This system allows the formation of groups of patients which can be either very specific or very broad by appropriate combination of selection criteria in the different categories. No codes are used but computer validation ensures consistent nomenclature. Computerisation allows rapid searching of records even with multiple selection criteria. The program is simple to use and validates data entries. An additional benefit is that it facilitates medical audit of the department's work.
