Artifacts associated with eye motion, misidentification of retinal layers, projections, and low optical coherence tomography signal are the most prevalent types. Artifacts in OCTA images are the major limitations of this diagnostic modality in clinical practice and identification of these artifacts and measures to mitigate them are essential ...

Jun 11, 2023 · Optical coherence tomography (OCT) enables ophthalmologists to measure retina thickness on a cellular level and has revolutionized the way we practice ophthalmology. Considering how ubiquitous this technology is, it’s essential that you are able to …

Oct 1, 2014 · Despite major improvements in OCT technology, artifacts can still lead you—and your patients—down the wrong path. Learn tricks for avoiding the traps. Even as technology advances, familiar problems may remain. Take, for instance, optical …

Optical Coherence Tomography (OCT) is a non-invasive diagnostic technique that renders an in vivo cross-sectional view of the retina. OCT utilizes a concept known as interferometry to create a cross-sectional map of the retina that is accurate to within at least 10-15 microns.

In recent years, ophthalmologists widely depend on optical coherence tomography (OCT), which is an objective, reliable, and repeatable structural test for both early diagnosis of glaucoma and detecting progression of the disease.

In this work, we present an algorithm to identify shadowed areas in OCTA of healthy subjects as well as patients with diabetic retinopathy, uveitis and age-related macular degeneration. The aim is to exclude these areas from analysis so that the overall OCTA parameters are minimally affected by shadow artifacts. 1. Introduction.

2 days ago · This interactive online course with twenty case vignettes is designed to teach residents about the various elements and layers of a normal retina in an OCT scan, how to accurately identify and describe retinal pathologies and the location of abnormalities in OCT images, and how to diagnose retinal pathology and suggest next steps in the evaluation or treatment of eye disease.

Oct 11, 2024 · Detecting and removing these shadow artifacts are crucial when quantifying indicators of retinal disease progression. We simplified an optical attenuation model of shadow formation in OCTA to a linear illumination transformation. And learn its parameters using an adversarial neural network.

Feb 19, 2021 · Speckle noise and retinal shadows within OCT B-scans occlude important edges, fine textures and deep tissues, preventing accurate and robust diagnosis by algorithms and clinicians. We developed a single process that successfully removed both noise and retinal shadows from unseen single-frame B-scans …

Oct 6, 2024 · Optical coherence tomography is a widely used imaging technique for diagnosing and monitoring the progression of many ophthalmic diseases. This technique provides real-time cross-sectional images of ocular tissues, including but …
