Polarization-Sensitive Optical Coherence Tomography

Caption

Tomography is central for measuring global corneal geometry, but its limitations create a diagnostic gap, especially for early detection. PS-OCT may address this issue by combining ultrahigh-resolution tomography with polarization-sensitive functional imaging that can help distinguish true early disease from naturally thin but healthy corneas by focusing on collagen organization rather than thickness alone. Left column: eyes classified as healthy; middle, subclinical; right, keratoconus.
