Description

<p>Purpose: We developed a training software for performing Goldmann perimetry (GP) that records the track of the stimulus. We analyzed how the visual field (VF) was tested with this software and evaluated our technical training program for performing GP.</p><p>Methods: Using the software, a VF with glaucomatous changes was examined by 6 orthoptic students and 6 orthoptists with clinical experiences for at least 5 years. The movement of the stimulus in the periphery obtained by the students and orthoptists was analyzed and compared.</p><p>Results: The orthoptists could plot more response points than the students, especially in the area with VF defects. The average stimulus speed was about 5°/sec and was 2°/sec right before the response points being connected for both students and orthoptists. The students moved the stimulus at a constant speed while the orthoptists moved the stimulus at a gradually decreasing speed.</p><p>Conclusions: In a VF test, it is important that the examiner has some general assumption about the VF defects to be tested. This training software can help the examiners become more familiar with various VF test results and acquire necessary skills in performing GP.</p>
