Retinal Nerve Fiber Layer Progression in Glaucoma: A Comparison between Retinal Nerve Fiber Layer Thickness and Retardance – Corrected Proof

Objective: To investigate the performance of spectral-domain optical coherence tomography (OCT) and scanning laser polarimetry to detect progressive retinal nerve fiber layer (RNFL) changes and to determine whether reduction of the RNFL retardance occurred before thinning of the RNFL in glaucoma.Design: Prospective, longitudinal study.Participants: One hundred eighty-four eyes of 116 glaucoma patients and 43 normal eyes of 23 healthy individuals.Methods: Patients were followed up every 4 months for at least 36 months with RNFL retardance (GDx Enhanced Corneal Compensation; Carl Zeiss Meditec) and RNFL thickness (Cirrus HD-OCT; Carl Zeiss Meditec) measured in the same visit. Progressive RNFL retardance and thickness (Read more...)
