G Grader

Glaucoma Cup-Disc Segmentation and Cup-Disc Ratio Calculation

Description

Glaucoma is a group of eye diseases that damages the optic nerve which carries the message of sight from the eye to the brain. This can lead to vision loss if not detected early and treated effectively. What is most threatening is that at-risk patient might not know he/she has glaucoma till 50% of the peripheral visual field is lost permanently.

G Grader is an AI-based system to detect glaucoma abnormal condition from standard fundus images. It provides automatic optical disc and cup segmentation and cup-disc-ratio (CDR) calculation for screening suspect glaucoma patients quickly.
