Summary
This study measured ophthalmic artery (OA) diameters using CTA, finding variations linked to patient age and sex. These ophthalmic artery measurements provide insights into cerebrovascular morphometrics.
Area of Science:
- Ophthalmology
- Radiology
- Vascular Anatomy
Background:
- The ophthalmic artery (OA) is a critical intracranial vessel.
- Understanding OA morphometrics and variations is essential for diagnosing vascular pathologies.
Purpose of the Study:
- To accurately measure ophthalmic artery (OA) diameter.
- To investigate bilateral OA diameter variations in relation to patient age and sex.
- To analyze OA morphometrics in reference to the internal carotid artery (ICA) caliber.
Main Methods:
- Retrospective analysis of 80 computed tomography angiographic (CTA) examinations.
- Bilateral measurement of 160 ophthalmic arteries (OAs).
- Comparison of OA and internal carotid artery (ICA) calibers.
Main Results:
- Ophthalmic artery (OA) diameter measured at 1.38±0.24 mm.
- Internal carotid artery (ICA) narrowing observed at 1.5±0.25 mm.
- Statistically significant variations in OA and ICA calibers identified between sexes and age groups.
Conclusions:
- Bilateral ophthalmic artery (OA) diameter variations exist.
- Age and sex are significant factors influencing OA and ICA morphometrics.
- CTA provides valuable data for assessing ophthalmic artery (OA) and internal carotid artery (ICA) variations.

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
