Normative Retardation Data Corrected For the Corneal Polarization Axis With Scanning Laser Polarimetry

摘要

To evalu-ate the distribution of retinal nerve fiber layer thickness measurements in normal eyes corrected for corneal polarization axis (CPA).Complete ocular examination, standard automated perimetry, peripapillary and macular scanning laser polarimetry imaging, and CPA measurements were performed in normal eyes. A noninva-sive device mounted on a slit lamp that incorporated two crossed linear polarizers and an optical retarder to measure the slow axis of corneal birefringence was constructed. One eye per patient was enrolled. Exclusion criteria consisted of visual acuity of less than 20/40, a refractive error exceeding ± 5.0 diopter sphere, 2.0 diopter cylinder, or both, previous intraocular surgery, or ocular disease except cataract.
