Microrobotic Catheterization of the Ophthalmic Artery for Targeted Treatment of Retinoblastoma

Advanced Intelligent Systems, EarlyView.
A microrobotic platform is presented that allows teleoperated and autonomous navigation of flow‐driven magnetic microcatheters, MagFlow, into the ophthalmic artery for superselective intra‐arterial infusion of chemotherapy to treat retinoblastoma. Extensive benchtop validations with patient‐derived biomimetic phantoms under optical and fluoroscopic ...

Retinal Vessel Segmentation: A Comprehensive Review From Classical Methods to Deep Learning Advances (1982–2025)

Advanced Intelligent Systems, EarlyView.
Four decades of retinal vessel segmentation research (1982–2025) are synthesized, spanning classical image processing, machine learning, and deep learning paradigms. A meta‐analysis of 428 studies establishes a unified taxonomy and highlights performance trends, generalization capabilities, and clinical relevance.

Volumetric microvascular imaging of human retina using optical coherence tomography with a novel motion contrast technique [PDF]

, 2009
Phase variance-based motion contrast imaging is demonstrated using a spectral domain optical coherence tomography system for the in vivo human retina. This contrast technique spatially identifies locations of motion within the retina primarily associated

Better 10‐Year Cerebrovascular Outcome After Transplant Than on Standard‐Care in Sickle Cell Anemia: DREPAGREFFE Trial

American Journal of Hematology, EarlyView.
ABSTRACT Management of cerebral vasculopathy in sickle cell anemia (SCA) includes standard‐care, that is, chronic transfusion (CT) or hydroxyurea, and hematopoietic cell transplantation (HCT). DREPAGREFFE‐1 (December 2010/June 2013), a French multicenter trial, was the first prospective trial comparing standard‐care to match sibling donor (MSD)‐HCT in ...

Diagnostic accuracy of Doppler ultrasound technique of the penile arteries in correlation to selective arteriography [PDF]

, 1988
In 63% of 265 patients with erectile dysfunction a relevant arterial inflow disturbance was found by Doppler ultrasound examination. Correlation between Doppler and arteriography in 58 patients showed an accuracy of 95% in detecting penile arteries and ...

Vascular Abnormalities in Hypermobile Ehlers–Danlos Syndrome: A Retrospective Cohort Study

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Hypermobile Ehlers–Danlos syndrome (hEDS), while generally free from severe vascular complications, may occasionally present with cardiac and vascular abnormalities that warrant specific investigation. While studies have been conducted on the prevalence of cardiac involvement, none have focused on vascular aspects. This retrospective study was
