Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, Volume 38, Issue 32, 8 June 2026.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Choroidal Thickness in Unilateral Advanced Glaucoma

Investigative Opthalmology & Visual Science, 2012
To investigate whether choroidal thickness measured using optical coherence tomography (OCT) in eyes with advanced glaucoma differs from that of fellow eyes with no or mild glaucoma.Thirty-six patients with advanced glaucoma in one eye and with no glaucoma or mild glaucoma in the fellow eye underwent macular scanning using enhanced depth imaging OCT ...

The prechoroidal cleft in neovascular age‐related macular degeneration

Acta Ophthalmologica, Volume 104, Issue 4, Page 364-375, June 2026.
Abstract The prechoroidal cleft is a lenticular, hypo‐reflective space on optical coherence tomography imaging, located between a band of fibrovascular material underneath the retinal pigment epithelium (RPE) and Bruch's membrane. It occurs in 8%–22% of neovascular age‐related macular degeneration (nAMD) eyes, most often with macular neovascularization

Seasonal variation in the incidence of central serous chorioretinopathy: A systematic review and meta‐analysis

Acta Ophthalmologica, Volume 104, Issue 4, Page 355-363, June 2026.
Abstract Central serous chorioretinopathy (CSC) is a chorioretinal disease characterised by serous subretinal fluid (SRF) in the macula, resulting in sudden central vision loss. It predominantly affects working‐age adults, particularly men aged 30 to 60 years.

Advancing Brain and Body Vascular Imaging in Bipolar Disorder: A Report From the International Society for Bipolar Disorders Vascular Task Force

Bipolar Disorders, Volume 28, Issue 4, June 2026.
ABSTRACT Objectives The heart–brain nexus is increasingly recognized as important for human health. Nonetheless, integration of this perspective in research and treatment remains limited in psychiatry, particularly in bipolar disorder (BD). Multisystem vascular imaging may help elucidate mechanisms linking heart and brain health in BD.
