Abstract
A complete instrumentation suite has been constructed for use in a randomized clinical trial to be funded from the National Institute of Health and study the underlying potential mechanism(s) of vision therapy. This suite is designed to track rotation of each eye (vergence) as well as measure the lens power of the eye's lens (accommodation). The system is designed to dissect the near triad which is composed of the pupil constriction, vergence and accommodation. The visual targets are programmed to be shown on two sets of computer screens which allowed vergence, accommodation and proximal vergence cues to be presented in isolation or in combination to study the Maddox components of vergence. This instrument uses FDA approved devices for subject safety. In our custom LabView based software, the Haploscope is able to generate ocular stimuli from programmed scripts, record data, as well as perform other various experimental requirements. Post processing is done in a MATLAB GUI environment. The results support that vergence responses can be studied using one to several visual cues.
