Abstract
Our sensory organs make us more confident and dependable. Glaucoma which causes damage to the optic nerves is “the sneak thief of sight” as there are no symptoms, and once the vision is lost, then it is permanent. The data from the Glaucoma Research Foundation states that over 60 million people worldwide are affected by glaucoma. This is one of the leading causes of irreversible blindness. Hence, it is very important to detect glaucoma and treat it well at its early stage itself. Electroretinography is one of the methods which can show the status of the cells present in the retina of the eye. Increase in intraocular pressure is a significant information by which one can suspect whether the person has chances for the occurrence of glaucoma or not. Tonometry is used to detect the intraocular pressure. The increase in the pressure has adverse effect on optic disc and optic nerves. Further, using retinal fundus image and applying image processing techniques on that, one can analyse the episode of upcoming eye disorder. The processing of the image includes the preprocessing techniques and segmentation techniques. The active contour method is one of the reliable methods. These procedures can help the population to deal with glaucoma at its early stage itself such that they can get rid of the unwanted blindness.
