Purpose: To describe the time course of management of patients with amaurosis fugax and analyze differences in management by different specialties.
Methods: Patients diagnosed with amaurosis fugax and subjected to carotid ultrasound in 2004-2010 at the Sahlgrenska University Hospital, Gothenburg, Sweden (n=302) were included in this retrospective cohort study, and data were collected from medical records.
Results: The prevalence of significant carotid stenosis was 18.9%, and 14.2% were subjected to carotid endarterectomy. A trend of longer delay for surgery was noted for patients first consulting a general practitioner (=0.069) as compared to hospital-based specialties. For 46.3% of the patients, an ophthalmologist was their first medical contact. No significant difference in time interval to endarterectomy was seen between ophthalmologists and neurologists/internists. Only 31.8% of the patients with significant carotid stenosis had carotid endarterectomy within 2 weeks from the debut of symptoms, and this proportion was smaller for patients residing outside the Gothenburg city area (=0.038).
Conclusion: Initially consulting an ophthalmologist does not delay the time to ultrasound or carotid endarterectomy. The overall time from symptoms to surgery is longer than recommended for a majority of the patients, especially for patients from rural areas and for patients initially consulting a general practitioner.

Carotid artery atherosclerotic stenosis is an important annual cause of stroke in the United States. Moreover, the incidence of carotid artery stenosis is significantly increasing due to the widespread popularity of high fat and high salt diets, sedentary lifestyles, and the increasing age of the population. Of major importance to cardiovascular specialists is the fact that individuals with atherosclerotic carotid artery stenosis can have a prevalence of atherosclerotic coronary artery disease as high as 50 to 75%.

Article Synopsis
- Delays in healthcare processes can lead to serious health issues, highlighting the need for better understanding of current processes through flowcharts generated from real-world data.
- This study analyzed physician insurance claims and hospital data for patients who had carotid endarterectomy, aiming to find the reasons behind treatment delays between 2008 and 2014.
- Results showed that each patient experienced unique treatment timelines, and while some medical activities were beneficial, others, like unnecessary follow-ups, contributed to delays in surgery, with the flowchart from the data being difficult to interpret.

Background: The long-term neuro-ophthalmic outcomes after carotid intervention in patients presenting with preoperative visual symptoms vary widely based on the underlying etiology of retinal ischemia and are not well understood.
Methods: We performed a retrospective review of consecutive patients presenting with retinal ischemia who subsequently underwent carotid intervention from January 2018 to December 2022. Patients were classified into three groups (group I: amaurosis fugax/vascular transient monocular vision loss, group II: ocular ischemic syndrome [OIS], and group III: central/branch retinal artery occlusion).

Oxaliplatin is a common drug used in the management of colorectal malignancies. Rare neurological side effects including amaurosis fugax, urinary retention, stroke, cranial nerve palsy, dysarthria, and dysphagia have been reported in the literature. Usually, such incidences are reported immediately after 1st dose of oxaliplatin infusion.
