Abstract
Glaucoma is an acquired progressive optic neuropathy which is characterized by changes in the optic nerve
head and retinal nerve fiber layer (RNFL). White‑on‑white perimetry is the gold standard for the diagnosis
of glaucoma. However, it can detect defects in the visual field only after the loss of as many as 40% of the
ganglion cells. Hence, the measurement of RNFL thickness has come up. Optical coherence tomography and
scanning laser polarimetry (SLP) are the techniques that utilize the evaluation of RNFL for the evaluation of
glaucoma. SLP provides RNFL thickness measurements based upon the birefringence of the retinal ganglion
cell axons. We have reviewed the published literature on the use of SLP in glaucoma. This review elucidates
the technological principles, recent developments and the role of SLP in the diagnosis and monitoring of
glaucomatous optic neuropathy, in the light of scientific evidence so far.
