Treffer: Computer Based Diagnosis of Glaucoma using Digital Fundus Images.

Glaucoma is an eye disease which occurs due to the increased/decreased fluid pressure inside the eye. The pressure inside the normal eye is below 21mm of Hg. When the pressure inside the eye(s) increases more than 21mm of Hg, the optic nerve is damaged. This can permanently damage vision in the effected eye(s) and can lead to blindness if left untreated. The main objective of this paper is to map the person's eye color image with database of images consisting of normal person as well as images of people suffering from glaucoma. The images' having different color variations inside the eye is compared by using images taken by high definition laser camera. These are called as fundus images. The feature extraction of these fundus images may be carried out using MATLAB software tool. By measuring the color pixels in the affected area the observation shows that the person is suffering from Glaucoma or not. To tell whether the person is suffering from Glaucoma, a test is made using the image of a normal person which is kept as reference (say zero) and then compared with the clinical observations of the person's image. Further if the result is positive (person is affected with Glaucoma) then also check for the three types of Glaucoma. [ABSTRACT FROM AUTHOR]
