Currently, few reports exist regarding optic disk melanocytoma features using swept-source OCT- A. This new technology may become a good alternative for following these lesions, perhaps improving the tumor extension detection, identification of progression and finally differentiating it from other neoplasms, including choroidal malignant melanoma.

Optical coherence tomography (OCT) is an imaging technique used widely in the management of macular diseases and glaucoma but it is gaining popularity in neurologic and neuro-ophthalmologic conditions as well . The major achievement of OCT is by documentation of quantitative changes in the optic nerve head ( atrophy, edema or normal)

Specific OCT hallmarks, such as “V contour” and a “lumpy-bumpy” appearance, associated with optic disc edema and optic nerve head drusen, respectively, were investigated in isolation from line scans added to photographs of various elevated ONHs in a web-based survey distributed among Australian and New Zealand optometrists.

Optical coherence tomography angiography (OCTA) is a novel technology that provides high resolution mapping of the retinal and optic disc vessels. Recent studies have shown the ability of OCTA to visualize vascular abnormalities in different optic neuropathies.

2019年8月14日 · Optical coherence tomography (OCT) is a non-invasive technique for cross-sectional tissue imaging. It typically uses light in the near-infrared spectral range which has a penetration depth of several hundred microns in tissue.

2019年9月5日 · Advanced optic nerve imaging, including optical coherence tomography (OCT) can be used to diagnose and characterize ODD with very high resolution. Enhanced depth imaging (EDI-OCT) in particular has emerged as the optimal modality to directly visualize ODD.

Optical coherence tomography (OCT) is able to determine the optic disc margin automatically. The aim of this study was to investigate the accuracy of the automatic OCT optic nerve head measurements in the presence of peripapillary atrophy.

Does the OCT Do It Better? The 6mm x 6mm cube is captured with 200 A-scans per B-scan, 200 B-scans. AutoCenterTM function automatically centers the 1.73mm radius peripapillary calculation circle around the disc for precise placement and repeatable registration. The RNFL thickness map shows the patterns and thickness of the nerve fiber layer.

This paper reviews the main research on Optical Coherence Tomography (OCT), focusing on the progress and advancements made by researchers over the past three decades in its methods and medical imaging applications. ...

Ancillary investigations, including optical coherence tomography (OCT), should be undertaken to help inform a working diagnostic “hypothesis,” which has already been formulated based upon details derived from the history and salient clinical signs found on examination.
