SLP (Scanning Laser Polarimetry) technology

Scanning Laser Polarimetry (SLP) is an imaging technique used to measure the thickness of the nerve fibers in the retina’s optic nerve head. It works by shining a low-power laser beam into the eye and analyzing how the light's polarization changes as it reflects off the nerve fibers. Since thicker nerve fiber layers alter the light's polarization more, SLP can detect thinning or damage related to eye conditions like glaucoma. This non-invasive, precise method helps eye care professionals monitor disease progression and assess optic nerve health over time.
