Summary
Carotid artery obstruction, often from atheromatous plaque, is the primary cause of ocular ischemic syndrome (OIS). Recognizing OIS symptoms like transient monocular blindness is crucial for prompt, multi-specialty management.
Area of Science:
- Neurology
- Ophthalmology
- Vascular Medicine
Background:
- Cerebral vascularization relies on internal carotids, vertebral arteries, and the Willis circle.
- Carotid artery obstruction is the most common cause of ocular ischemic syndrome (OIS).
- Obstructions stem from atheromatous plaque, external compression, arteritis, or dissection.
Purpose of the Study:
- To highlight the link between carotid artery pathology and ocular ischemic syndrome.
- To detail the signs, symptoms, and causes of OIS.
- To emphasize the importance of early recognition and multi-specialty management for OIS.
Main Methods:
- Review of literature on carotid artery diseases and their ocular manifestations.
- Analysis of clinical presentations associated with severe ocular hypoperfusion.
- Discussion of diagnostic and management strategies for OIS.
Main Results:
- Atheromatous lesions of the carotid artery are the most frequent cause of OIS.
- OIS symptoms include transient monocular blindness (TMB), persistent monocular blindness, ocular ischemia, Claude Bernard Horner syndrome (CBH), and oculomotor palsies.
- Other vascular emergencies include carotid artery dissection, Horton arteritis, aneurysms, and carotid-cavernous fistula.
Conclusions:
- Carotid artery pathology is a critical, potentially life-threatening condition.
- Prompt recognition of OIS signs and symptoms is vital for patient outcomes.
- A multi-specialty approach is essential to prevent misdiagnosis and optimize patient management.

Arteries of the Head and Neck
2.3K
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...

Glaucoma: Overview
1.1K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Angle Closure Glaucoma: Treatment
958
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Open Angle Glaucoma: Treatment
832
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Veins of Head and Neck
4.2K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...
