Perceptual-assisted Adversarial Adaptation for Choroid Segmentation in optical coherence tomography [PDF]
arXiv, 2019 Accurate choroid segmentation in optical coherence tomography (OCT) image is vital because the choroid thickness is a major quantitative biomarker of many ocular diseases. Deep learning has shown its superiority in the segmentation of the choroid region but subjects to the performance degeneration caused by the domain discrepancies (e.g., noise level ...

Choriocapillaris Flow Signal Impairment in Sorsby Fundus Dystrophy [PDF]
arXiv, 2021 Purpose: To quantify choriocapillaris flow alterations in early Sorsby Fundus Dystrophy (SFD) and to investigate the relationship of choriocapillaris flow with the choroidal and outer retinal microstructure. Methods: In this prospective case-control study, 18 eyes of 11 patients with early SFD and 32 eyes of 32 controls without ocular pathology ...

Choroid plexus in developmental and evolutionary perspective
Frontiers in Neuroscience, 2014 The blood-cerebrospinal fluid boundary is present at the level of epithelial cells of the choroid plexus. As one of the sources of the cerebrospinal fluid, the choroid plexus plays an important role during brain development and function.

Eliminating Shadow Artifacts via Generative Inpainting Networks to Quantify Vascular Changes of the Choroid [PDF]
arXiv, 2019 Shadow artifacts from retinal vessels hinder the development of quantitative choroidal biomarkers in Optical Coherence Tomography (OCT), which limits the clinical applications of the choroidal OCT to the measures of layer thickness. In this paper, we present a novel framework that could eliminate the retinal shadows and realize the quantification of ...

Journal of the American Medical Association, 1914 To the Editor: —Some years ago a child was brought to me who had suddenly developed partial blindness during an attack of rubeola. Ophthalmoscopic examination revealed choroiditis, which advanced to partial atrophy. This case caused me to investigate, and revealed the fact that but few cases of choroidal atrophy can be found which will not furnish a ...

Automatic Segmentation of Choroid Layer in EDI OCT Images Using Graph Theory in Neutrosophic Space [PDF]
arXiv, 2018 The choroid is vascular tissue located underneath the retina and supplies oxygen to the outer retina; any damage to this tissue can be a precursor to retinal disease. Choroid is almost invisible in Enhanced Depth Imaging Optical Coherence Tomography (EDI-OCT) images and it is hard for an ophthalmologist to detect this layer manually.

Exploration, EarlyView.The discovery of the glymphatic system has opened up a pathway for drug delivery to the brain by circumventing the blood‐brain barrier, which can effectively improve drug utilization. The methods of drug delivery through the glymphatic system include intrathecal injection, intranasal injection, and delivery through the meningeal lymphatic vessels.

Engineered Exosome‐Based Senolytic Therapy Alleviates Stroke by Targeting p21+CD86+ Microglia
Exploration, EarlyView.We identified a harmful immune cell type, p21+CD86+ microglia, driving post‐stroke inflammation and developed a targeted exosome‐based therapy (Que@micro‐Exo) to eliminate these cells. This innovative treatment reduced inflammation, alleviated brain damage, and improved recovery in stroke models, offering a promising strategy for stroke and other ...

Clinical &Experimental Ophthalmology, Volume 50, Issue 9, Page 1013-1024, December 2022., 2022 Abstract Background To evaluate the long‐term efficacy and safety of continued repeated low‐level red‐light (RLRL) therapy on myopia control over 2 years, and the potential rebound effect after treatment cessation. Methods The Chinese myopic children who originally completed the one‐year randomised controlled trial were enrolled.

Choroid plexus volume enlargement in first-episode antipsychotic-naïve schizophrenia
SchizophreniaInvestigation of the choroid plexus in schizophrenia has seen growing interest due to its role in the interaction between neuroinflammation and brain dysfunction. Most previous studies included treated and long-term ill patients, while antipsychotics and
