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

Single‐Cell Annotation and Localization via Integrating Spatial Transcriptomics Maps the Mouse Ocular Atlas and RAO Dynamics

Advanced Science, EarlyView.
We developed the ASCAL pipeline, integrating complementary spatial transcriptomics, to construct a high‐fidelity mouse whole‐eye single‐cell atlas. Applying ASCAL to a retinal artery occlusion (RAO) model revealed spatially restricted immune activation localized to the ganglion cell layer and the selective depletion of a translationally active, outer ...

A Review of Artificial Intelligence in Ophthalmology: Key Aspects, Challenges, and Future Directions

Eye &ENT Research, EarlyView.
ABSTRACT Artificial intelligence (AI) is increasingly reshaping ophthalmology because the specialty depends heavily on structured imaging, quantitative measurements, and repeatable diagnostic workflows. This review provides a clinically grounded and translationally oriented synthesis of AI in ophthalmology, covering methodological foundations ...

Neovascular Glaucoma Due to Branch Retinal Vein Occlusion Combined with Branch Retinal Artery Occlusion [PDF]

Korean Journal of Ophthalmology, 2013
Branch retinal artery occlusion (BRAO) and branch retinal vein occlusion (BRVO) rarely cause neovascular glaucoma (NVG). A 58-year-old woman with hypertension and type 2 diabetic mellitus complained of progressive visual loss in her right eye for the previous 3 months. At initial examination, visual acuity was 20 / 63 in the right eye.

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

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.

The effect of rhegmatogenous retinal detachment on retinal oxygenation

Acta Ophthalmologica, EarlyView.
Abstract Purpose Little is known about the effects of retinal detachment on oxygen extraction from retinal vessels. The role of oxygen supply from the retinal vessels in a detached area has not previously been investigated in vivo in humans. Retinal oximetry is a non‐invasive measurement of retinal oxygen saturation.

En face localization of retinal telangiectatic capillaries using OCT compared with ICG angiography in chronic vascular macular oedema

Acta Ophthalmologica, EarlyView.
Abstract Purpose Retinal telangiectatic capillaries (TelCaps) are microvascular abnormalities associated with chronic vascular macular oedema and suboptimal response to intravitreal therapy. Targeted laser photocoagulation is beneficial but requires precise localization using indocyanine green angiography (ICG‐A), the reference standard. However, ICG‐A
