On optical coherence tomography (OCT), cotton wool spots can appear as focal or segmental areas of thickening and hyperreflectivity of the inner retinal layers in the acute phase.

Mar 15, 2021 · Besides the typical funduscopic appearance, a CWS can also be identified and monitored using optical coherence tomography (OCT). Since these lesions accumulate within the RNFL, the abnormality on OCT is typically found within this inner retinal layer.

Feb 8, 2017 · A CWS is seen as a white indistinct retinal lesion. OCT reveals a localized RNFL thickening in the most anterior part of the image. Though sometimes ophthalmoscopically similar to drusen or exudates, a CWS is much more superficial to either of those lesions and thus easily distinguished with OCT.

In this study, spectral domain optical coherence tomography (SD-OCT) with mapping was used to demonstrate in vivo the characteristics of an isolated CWS in a 59-year-old patient as well as its appearance immediately after ophthalmoscopic resolution.

Nov 10, 2023 · Cotton wool spots (CWS) are retinal lesions that typically represent local ischemia, a condition where there is an inadequate blood supply to the retinal nerve fibers due to obstruction or narrowing of the retinal blood vessels.

Oct 1, 2013 · Cotton-wool spots (CWS) (Figure) are acute signs of vascular insufficiency to an area of retina. They have been described in many conditions, but only occasionally cause symptoms in patients. The most common symptoms associated with retinal CWS can include scotoma, arcuate defects, blurred vision, and amaurosis fugax.

Jun 12, 2023 · Cotton wool spots (CWS) are fluffy white or yellow spots that can appear on the retina. While the spots themselves don’t typically cause problems, they often indicate an underlying condition. A CWS can be a cause for concern in an otherwise healthy individual.

To demonstrate the utility of a retinal imaging technique using spectral domain optical coherence tomography (SD-OCT) for creating a B-scan layer-by-layer analysis to aid in the differential diagnosis of various retinal dots, spots, and other white lesions. Review.

Mar 17, 2021 · This longitudinal study describes the course of CWS in COVID‐19 on SD‐OCT and OCTA, which confirmed their previously observed localisation and morphology on SD‐OCT with CWS of other diseases.

The purpose of our study was to analyze the long-term changes in areas of healed CWS using new technology: the Spectral Domain OCT. We used a spectral-domain OCT and simultaneous confocal SLO imaging (SD-OCT/SLO), the Heidelberg Spectralis …
