Three-Dimensional Characteristics of Choroidal Vasculature Associated With Filling Delay in Central Serous Chorioretinopathy.

Purpose: The purpose of this study was to investigate circulatory disorders in central serous chorioretinopathy (CSC), we analyzed the three-dimensional (3D) structure of the choroidal vessels in filling delays seen on indocyanine green angiography (ICGA) images.

Methane diffusion affects characteristics of benthic communities in and around microbial mat-covered sediments in the northeastern Japan sea.

We investigated relationships between features of benthic macrofaunal communities and geochemical parameters in and around microbial mat-covered sediments associated with a methane seepage on Sakata Knoll in the eastern Japan Sea. A depression on top of the knoll corresponds to a gas-hydrate-bearing area with seepage of methane-rich fluid, and microbial mats cover the seafloor sediments. Sediment cores were collected at three sites for this study: one within a microbial mat, a second a few meters outside of the microbial mat, and a third from a reference site outside the gas-hydrate-bearing areas.

Micro-abnormalities in the retina and choroid induced by anti-CTLA4 treatment.

Anti-Cytotoxic T-Lymphocyte Associated protein 4 agents, such as ipilimumab, are widely applied to various cancers. However, they cause immune-related adverse effects throughout the body, including the eye. This study examined whether ipilimumab induces retinal and choroidal abnormalities in rodents, and investigated potential underlying mechanisms.

Occlusion of a Vortex Vein After Treatment With Half-Fluence Photodynamic Therapy Combined With Intravitreal Aflibercept Injection for Pachychoroid Neovasculopathy.

Photodynamic therapy (PDT) is a treatment option for pachychoroid diseases such as central serous chorioretinopathy (CSC), pachychoroid neovasculopathy (PNV), polypoidal choroidal vasculopathy (PCV), and peripapillary pachychoroid syndrome (PPS). On the other hand, morphological changes of choroidal vessels in the irradiated field after PDT have also been discussed, with occlusion of choriocapillaris and stenosis of choroidal middle and large vessels being reported. Here, we report a case of vortex vein occlusion after half-fluence PDT (HF-PDT) combined with an anti-vascular endothelial growth factor (VEGF) agent for PNV.

Clinical characteristics and pachychoroid incidence in Japanese patients with neovascular age-related macular degeneration.

The phenotypes of neovascular age-related macular degeneration (nAMD) are recognized as differing between Caucasian and Asian patients. Pachychoroid is thought to be more prevalent in Asians than in Caucasians, and may be involved in the development of nAMD in Asian patients. Therefore, we investigated the clinical characteristics and pachychoroid incidence in Japanese patients with nAMD.
