A Review on Glaucoma Disease Detection Using Computerized Techniques

Glaucoma is an incurable eye disease that leads to slow progressive degeneration of the retina. It cannot be fully cured, however, its progression can controlled in case early diagnosis. Unfortunately, due absence clear symptoms during stages, diagnosis are rare. must detected at stages since late lead permanent vision loss. affects retina by damaging Optic Nerve Head (ONH). Its dependent on measurements Cup (OC) and Disc (OD) Computer techniques have been shown diagnose glaucoma effectively correctly with little overhead. These measure OC dimensions using machine learning based classification segmentation algorithms. This article aims provide a comprehensive overview various existing use detect fundus images. Readers would able understand challenges presents from image processing stand-point will identify gaps current research.
