2024年2月25日 · OCT hypointense bands are a novel biomarker in RVOD indicating delayed AV transit and pulsatile filling without the need for dye angiography. Structural OCT often shows PAMM in these eyes and, less commonly, a p-MLM sign. Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article.

In this article, we summarize the interpretations of clinical OCT and adaptive optics (AO) OCT (AO-OCT) of the outer retina in the human eye, and briefly review OCT investigation of the outer retina in animal models. Quantitative analysis of outer retinal OCT bands is compared to established parameters of retinal histology.

Incorporate new information from High Res-OCT supporting two reflective bands in the outer plexiform layer (OPL), 21 in apparent correspondence to layers of mitochondria visualized by volume electron microscopy (Figs. 5 and 3 of reference 21, respectively). OPL contains synaptic terminals of photoreceptors and connecting processes of interneurons.

The innermost hyperreflective band, the OPL Dendritic Zone, includes the synaptic region of the rod spherules, cone pedicles, horizontal cells and bipolar cells. The thickened hyperreflective region at the inflection from attached to detached retina, as well as the hyporeflective band within detachment, is the OPL Henle’s Zone.

2022年4月4日 · Optical coherence tomography (OCT) (6, 7) can provide depth-resolved, cross-sectional images of individual retinal neural layers. As one special OCT modality, OCT angiography (OCTA) (8 – 11) can enhance the visibility of individual retinal capillary plexuses.

2025年3月17日 · The extent of loss of the outer retinal bands on OCT increased significantly over time in a cohort with intermediate AMD that was associated with changes in visual sensitivity, and measurements of EZ loss had the highest performance for capturing longitudinal changes.

The OPL lies between the INL and the ONL and, for the purposes of this study, consisted of two components on OCT: 1) a thin reflective band along the posterior border of the INL, thought to...

2024年10月1日 · OCT hypointense bands are a novel biomarker in RVOD indicating delayed AV transit and pulsatile filling without the need for dye angiography.

2024年7月18日 · Precise interpretation of the anatomical origins of outer retinal optical coherence tomography (OCT) presents technical challenges owing to the delicate nature of the retina. To address this challenge, our study introduces a novel polarization-sensitive full-field swept-source OCT (FF-SS-OCT) that p …

2020年7月1日 · Here, we propose an interpretation of the four outer hyperreflective OCT bands with a correspondence to retinal histology: the first and innermost band as the external limiting membrane (ELM), the second band as the cone ellipsoid zone (EZ), the third band as the outer segment tips phagocytosed by the pigment epithelium (PhaZ), and the fourth ...
