Scanning laser polarimetry

Scanning laser polarimetry is a medical imaging technique used primarily in ophthalmology to assess the structure of the eye, particularly the optic nerve. It uses a laser to shine light onto the eye and measures how the light’s polarization changes after interacting with the retinal tissue. These changes help detect early signs of glaucoma or other eye diseases by creating detailed images and maps of the optic nerve head. This non-invasive method is valuable for monitoring eye health and guiding treatment, as it provides crucial information without requiring physical contact with the eye.
