ABSTRACT
Computer-based storage of patient data is the basis for their comprehensive use in science and patient care. Developing a data base for storage and interpretation of strabologic data must be prepared by an analysis of data items, terminologies, and diagnostic methods. We analyzed patient data collections and constructed a minimal strabologic data structure focused on methods for the examination of eye-muscle function. Geometric methods for the analysis of Hess charts help to prepare diagnostic parameters for assignment of Hess-result figures (classified according to their shapes) to certain diagnoses of muscle paresis. In this way the system can help in preparing and verifying diagnoses and structuring data according to various scientific or patient-management needs. Moreover, the system can support diagnostic training as it can present Hess charts, related diagnoses, and geometric parameters in a concise manner and hence enable learners to understand the diagnostic procedure.

The examination of near heterophoria with a heterometer using a large series of test plates presented "free-sighted" (i.e., not hindered by optical or mechanical means) enables a more comprehensive analysis to be made than has so far been achieved with other instruments. The principal components of the instruments are an angle mirror and various test panels. The selection of test panels currently available should be developed further. However, comparison with other instruments for examining near heterophoria justifies the conclusion that heterophoria or nearsightedness due to errors of refraction can be determined more easily with this instrument and hence treated more appropriately. Results of examination with the heterometer, combined with exhaustive application of comprehensive analytical test procedures, will probably help to extend our knowledge of the control sequence of binocular coordination in near vision. The instrument has already proved its value not only in orthoptic departments, clinics, and ophthalmologists' offices, but also for determining refractive indices and for screening. It can therefore be recommended for the diagnosis of near heterophoria.
