Abstract

Computer Assisted Simultaneous Analysis (C.A.S.E.) aims to aide a practitioner in an optometric exam to promptly obtain an organized insight of a patient's binocular behavior simultaneously to the progression of an optometric binocular exam. The program is constructed to serve as a record pad upon which the results of optometric tests are recorded as they normally would in an ordinary exam. As test results are recorded, the program initiates a series of algorithms which transforms gross findings into net findings according to formulas recommended in the optometric literature and compare the results to OEP accepted norms. The program then organizes the findings in chains (automatic checking and chaining) which are displayed as the exam progresses. Further, the program classifies and diagnoses the chained clusters according to pre-established syndromes delineated by the OEP functional analysis system (Bl-B2-C system). The degree of functional degeneration in each syndrome and the degree of embededness of visual behavior habits is also provided. Furthermore, different lens options are analyzed for best visual performance according to actual AC/ A ratios. OEP-established lens reccommendations ("mandates") are applied, and the best lens for treatment or prevention of accommodative and vergence dysfunctions are then made available in a button-driven electronic prescription pad which allows the examiner to immediately prescribe the selected option. The program differs from a simple analysis program in that it aims not to be an ancillary tool to be resorted to after the exam is concluded and the patient has left, but it consists of the record itself upon which an optometric exam is recorded, automatically providing otherwise time-consuming analysis as the patient still sits on the exam chair. The object is to render analysis results and recommendations as the practitioner finishes the exam, providing reference feedback when it is needed the most (as the exam progresses) and eventually achieve a paperless optometric record keeping system that can perform analytical and diagnostic tasks at no additional cost in time to the practitioner. Review and selection of lens alternatives for distance and near are made and recorded by the examiner by means of a button driven display. As an exam record system, C.A.S.E. does not a represent a complete system in that it presently limits itself to preliminary visual skills and phorometric findings. At its present stage, however, the program seeks to demonstrate that a complete record system with sophisticated diagnostic capabilities can be constructed. Two computer disks with the program accompany this work.
