Image processing for clinical diagnostics(Retinopathy of prematurity)

Blood vessels of retina begin to develop 3 months after conception

Complete development for normal birth

Prematurely born babies → disrupted eye development

Vessels grow abnormally → scar tissue → vision loss (five stages)

Treatment within 72 hours can help correct matters
