Summary
Peripheral ophthalmic artery aneurysms (POAAs) are rare but can cause significant visual impairment or hemorrhage. Surgical intervention is often necessary for symptomatic POAAs to preserve vision and prevent rupture.
Area of Science:
- Ophthalmology
- Neurology
- Vascular Surgery
Background:
- Peripheral ophthalmic artery aneurysms (POAAs) are rare vascular lesions distinct from carotid-ophthalmic aneurysms.
- Their clinical features and natural history are not well-established, necessitating further investigation.
Purpose of the Study:
- To conduct a comprehensive literature review of reported POAAs.
- To analyze the demographics, etiology, clinical manifestations, and treatment outcomes of POAAs.
Main Methods:
- A systematic literature search was performed to identify reported cases of aneurysms involving the ophthalmic artery (OA) segments.
- Data extraction focused on patient demographics, aneurysm location, clinical presentation, and treatment strategies.
Main Results:
- Thirty-five cases of POAAs were reviewed, involving intracranial, optic canal, intraorbital, lacrimal, and anterior ethmoidal segments.
- Eighteen patients suffered visual impairment, with seven experiencing improved visual acuity post-surgery.
- Intracranial and anterior ethmoidal POAAs pose a risk of rupture causing hemorrhage, while OA stem and lacrimal branch aneurysms threaten visual acuity.
Conclusions:
- POAAs, particularly those involving the OA stem and lacrimal branch, can lead to severe visual loss.
- Intracranial and anterior ethmoidal POAAs carry a risk of rupture and intracranial hemorrhage.
- Surgical treatment is crucial for symptomatic POAAs to prevent visual deterioration or manage rupture; conservative management may be considered for small, incidental POAAs.

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:30Peripheral Artery Disease I: Introduction
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
01:25Glaucoma: Overview
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...
01:10The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

01:30Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
01:28Angle Closure Glaucoma: Treatment
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...
