Summary
Vertebral artery dissection (VAD) can rarely present as homonymous hemianopia, a visual field defect. Early diagnosis using visual field testing is crucial for this rare condition.
Area of Science:
- Neuroscience
- Ophthalmology
- Vascular Neurology
Background:
- Vertebral artery dissection (VAD) is a rare condition.
- It can lead to posterior circulation infarctions.
- Atypical presentations can be challenging to diagnose.
Observation:
- A 30-year-old woman presented with a 4-month history of visual disturbances, vertigo, and dizziness.
- Examination revealed a small, congruous right inferior homonymous quadrantanopia.
- This visual field defect indicated a potential neurological issue.
Findings:
- Further investigation uncovered vertebral artery dissection (VAD).
- Multiple posterior circulation infarctions were identified, including a left occipital stroke.
- The stroke's location correlated with the observed visual field defect.
Implications:
- This case highlights VAD's rare presentation as homonymous hemianopia.
- Visual field testing is essential for diagnosing such atypical VAD cases.
- A high index of suspicion is necessary to avoid misdiagnosis and manage thromboembolic risks.

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.

01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
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...
01:12Visual Agnosia
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round end"...
