Visual Field (VF), as image data, is the spatial array of visual sensations available to observation in introspectionist psychological experiments. The retina, which surrounds the inner face of the eye, also consists of retinal nerve fiber layer and can be observed with Retina Nerve Fiver Layer (RNFL) Thickness data. They contain data obtained from Ophthalmologic diagnostic equipment. VF data is generally used to diagnose disease that occurs symptoms in the optic nerve and retina, such as glaucoma or macular degeneration etc. We should put the image data manually to develop a machine learning based diagnostic model so far. In this paper, we introduce how to extract numerical data we need automatically from images by using Optical Character recognizer(OCR) technology. Furthermore, we increased the recognition rates in this study, adding a function which detects errors on recognized numbers and corrects them. Based on this accumulated data, we built a glaucoma diagnostic model.
