Combined branch retinal vein and branch retinal artery occlusion – clinical features, systemic associations, and outcomes

Indian Journal of Ophthalmology, 2017
Purpose: Retinal vascular occlusions affecting both the arterial and venous systems are rare events. Combined branch retinal artery (BRAO) and vein (BRVO) occlusion are exceedingly rare and not well characterized. Methods: Six patients with combined BRAO

Association between retinal vein occlusion, axial length and vitreous chamber depth measured by optical low coherence reflectometry. [PDF]

, 2015
BACKGROUND: Results of ocular biometric measurements in retinal vein occlusion (RVO) eyes are still inconclusive and controversial. The aim of this study was to evaluate the association between ocular axial length (AL), vitreous chamber depth (VCD) and ...

Transcranial Color‐Coded Duplex Sonography in Large‐Vessel Vasculitis Compatible With Takayasu Arteritis Presenting Intracranial Involvement and Vertebrobasilar Dolichoectasia: A Case Report

Journal of Clinical Ultrasound, EarlyView.
This case illustrates sequential intracranial occlusions in large‐vessel vasculitis compatible with Takayasu arteritis preserving perfusion through robust collateral pathways. Transcranial color‐coded duplex sonography identified characteristic blunted flow patterns and focal turbulence, underscoring its value in detecting hemodynamic compromise beyond

Retinal Artery and Vein Occlusions Successfully Treated with Hyperbaric Oxygen [PDF]

, 2019
We present six cases of central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO) that we recently treated with hyperbaric oxygen (HBO2).

Epac2-deficiency leads to more severe retinal swelling, glial reactivity and oxidative stress in transient middle cerebral artery occlusion induced ischemic retinopathy [PDF]

, 2015
Ischemia occurs in diabetic retinopathy with neuronal loss, edema, glial cell reactivity and oxidative stress. Epacs, consisting of Epac1 and Epac2, are cAMP mediators playing important roles in maintenance of endothelial barrier and neuronal functions.

The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

Responsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

Aneurysms of the intracranial segment of the ophthalmic artery trunk. case report and systematic literature review [PDF]

, 2017
Aneurysms arising from the ophthalmic artery trunk (OAT) are very rare, particularly in the artery's intracranial course. The onset of a subarachnoid hemorrhage (SAH) from a ruptured OAT aneurysm in this segment is extremely rare.

Interventional oncology in children: Where are we now?

Journal of Medical Imaging and Radiation Oncology, EarlyView.
Abstract Paediatric Interventional Oncology (IO) lags behind adult IO due to a scarcity of specific outcome data. The suboptimal way to evolve this field is relying heavily on adult experiences. The distinct tumour types prevalent in children, such as extracranial germ cell tumours, sarcomas, and neuroblastoma, differ strongly from those found in ...

Amalric triangular sign in a case of central retinal artery occlusion combined with posterior ciliary artery occlusion – Case report

American Journal of Ophthalmology Case Reports, 2018
Purpose: Amalric triangular sign is a rare phenomenon indicating choroidal ischemia. In this study, we reported a typical Amalric triangular sign in a case of central retinal artery occlusion (CRAO) combined with posterior ciliary artery (PCA) occlusion.
