Antithrombotic use in retinal artery occlusion: A narrative review.
Kaohsiung J Med Sci
January 2025
College of Medicine, Chang Gung University, Taoyuan, Taiwan.
Retinal artery occlusion (RAO) is a critical ophthalmic emergency with a high risk of significant visual impairment. While traditional treatment aims to promptly restore blood flow to the retina, recent research has investigated the potential benefits of anticoagulation therapy for managing this condition. This paper reviews current literature and clinical trials investigating the efficacy and safety of anticoagulant and antiplatelet therapies, such as systemic heparinization and direct oral anticoagulants and aspirin, in treating RAO.

Purpose: To investigate the relationship between nocturnal blood pressure (BP) dip and parapapillary choroidal vessel density (pCVD) in patients with normal-tension glaucoma (NTG).
Methods: This study analyzed 267 eyes of 267 untreated NTG patients who underwent 24-hour (h) intraocular pressure (IOP) and ambulatory BP monitoring in the habitual position. Patients were classified into 3 groups [non-dippers (nocturnal BP dip < 10%), dippers (nocturnal BP dip between 10% and 20%, and over-dippers (nocturnal BP dip > 20%)], and pCVDs were measured by using optical coherence tomography angiography (OCTA) images.
Decreased Choriocapillaris Vessel Density in the Ipsilateral Eye after Carotid Artery Revascularization Detected by Widefield Swept-Source OCT Angiography.

Department of Ophthalmology, Sichuan University West China Hospital, Chengdu, Sichuan Province, China.
Objective: To investigate the short-term blood flow changes and image features of the retina and choroid in patients who underwent carotid artery revascularization (CAR) for severe carotid artery stenosis using widefield swept-source OCT angiography (OCTA).
Design: Prospective study.
Participants: This prospective study included 112 eyes (56 eyes on the ipsilateral side and 56 eyes on the contralateral side) of 56 participants with severe carotid artery stenosis.
Ankle-Brachial Index as a Predictor of Acute Ischemic Cerebrovascular Event After Central Retinal Artery Occlusion.
Med Sci Monit

Department of Neurology, Henan Provincial People's Hospital (People's Hospital of Zhengzhou University), Zhengzhou, Henan, China.
BACKGROUND Identifying patients at higher risk of acute ischemic cerebrovascular events (AICE) following central retinal artery occlusion (CRAO) is crucial for secondary prevention of stroke. This study aimed to investigate whether a low ankle-brachial index value is associated with an increased risk of AICE after CRAO. MATERIAL AND METHODS We prospectively analyzed patients who were admitted to our hospital because of CRAO between February 2019 and March 2023 and whose ankle-brachial index was no greater than 1.

Backgrounds/aims: Central retinal artery occlusion (CRAO) is a vision-devastating emergency. However, widely-acknowledged treatment consensus is lacking and prehospital delays commonly occur. Hence, we aimed to investigate the visual outcomes of conservative treatments (CT), local intra-arterial fibrinolysis (LIF) and hyperbaric oxygen (HBO) therapy for non-arteritic CRAO (NA-CRAO) patients beyond the conventional time window.
