      Optical Coherence Tomography Segmentation Errors of the Retinal Nerve Fiber Layer Persist Over Time
      Prcis: There are errors in automated segmentation of the retinal nerve fiber layer in glaucoma suspects or patients with mild glaucoma that appear to persist over time; however, automated segmentation has greater repeatability than manual segmentation. Purpose: To identify whether optical coherence tomography (OCT) segmentation errors in retinal nerve fiber layer (RNFL) thickness measurements persist longitudinally. Methods: This was a cohort study. We used spectral domain OCT (Spectralis, Heidelberg Engineering ...

      Optical coherence tomography evaluation of the optic nerve head neuro‐retinal rim in glaucoma
      Clinical examination of the optic disc is a fundamental component of any ophthalmic evaluation, but it is especially important for diagnosis and management of glaucoma. The purpose of this article is to: (1) review the limitations inherent to clinical examination; (2) outline the rationale for adopting into clinical practice quantitative measures of the optic nerve head neuro‐retinal rim tissue integrity derived from current optical coherence tomography imaging approaches; (3 ...
