TCA change significance maps of the example normal eye as in the HRT TCA software (b), and using the liberal (c), moderate (d), and conservative (e) criteria of progression.⁴ The change maps (b–e, optic disk region cropped for clarity) indicate retinal locations with likely glaucomatous changes (red superpixels) and treatment effects or improvement (green superpixels). (c–e) TCA detected no significant glaucomatous change (based on height change and red-cluster RC criteria) in the normal eye.
