Medical image processing is a technique and process of creating visual representation of the interior of a body. The fast growing development of digital imaging and computer vision has increased the potential of using the image processing technologies in medicine. And Image processing is particularly useful in medical diagnostic systems. The image of the retina is used to provide the necessary information regarding the sensory part of the visual system. Some of the retinal diseases are Pink Eye, Styes and Chalazia, Dry Eye, Flashes and Floaters, Diabetic Eye Disease, Glaucoma, Macular Degeneration. These retinal diseases are lead to the blindness. Among these Disease Glaucoma is one of the leading causes of blindness. Glaucoma is a condition that causes damage to eye's optic nerve. It is one of the leading causes of blindness. It can happen at any age, but is more common in older adults. The optic nerve, which transmits images to the brain, was affected by the increased pressure, called intraocular pressure. If this continues, Glaucoma can lead to permanent vision loss. Without treatment, Glaucoma can cause permanent blindness within a few years. Early detection, through regular and complete eye exams, is the key to protecting our vision from damage caused by glaucoma. This survey paper present a image processing technique for Automated diagnosis of Glaucoma.
