Main Article Content
Glaucoma is the second cause of vision loss and blindness, not only in developing countries deal with it, but developed countries also face it. The main problem of blindness from glaucoma is a lack of recognition, to clarify, the patients do not know whether they have glaucoma or not. As time pass by, it continues to develop from time to time, and most of the patients will realize about it when it has developed into a severe stage. According to the ophthalmology research, if the area ratio between the optic cup to the optic disc is greater than 1/3, patients will be classified as having glaucoma. The aim of this research is to develop the device to capture the image of the optic disc. Then, the image provided by the prototype, with the aid of image processing algorithm based on the area ratio of the optic cup to the optic disc, can be used to classify glaucomatous patients from healthy individual. From the result, the captured image of the optic disc, the location of the optic nerve head is clear. The image of the optic disc apparently shows brighter and dimmer section, which represents the optic cup and optic disc respectively. The image can be used for analysis of opened angle glaucoma via image processing algorithm, which are provided by many researchers [ 1,19,21,22].
