Insights

Moyamoya disease (MMD), a rare cerebrovascular condition, can cause central retinal artery occlusion (CRAO). This case report details a young patient with MMD experiencing CRAO, highlighting a rare but significant association.

Area of Science:

  • Neurology
  • Ophthalmology
  • Vascular Medicine

Background:

  • Moyamoya disease (MMD) is a rare, progressive stenosis of intracranial arteries.
  • Cerebrovascular manifestations are common, but ocular complications are exceptionally rare.
  • Central Retinal Artery Occlusion (CRAO) has diverse etiologies, including atherosclerosis, embolism, and vasculitis.

Purpose of the Study:

  • To report a rare case of Central Retinal Artery Occlusion (CRAO) in a young adult.
  • To investigate the association between CRAO and Moyamoya disease (MMD).
  • To highlight the importance of considering MMD in young patients presenting with CRAO.

Main Methods:

  • A case study of a 26-year-old patient presenting with CRAO in the right eye.
  • Cerebral angiography was performed to evaluate intracranial vasculature.
  • Clinical presentation and diagnostic findings were analyzed.

Main Results:

  • The patient was diagnosed with Moyamoya disease (MMD) based on typical cerebral angiography findings.
  • The patient presented with Central Retinal Artery Occlusion (CRAO) in the right eye.
  • This represents a rare co-occurrence of CRAO and MMD.

Conclusions:

  • Moyamoya disease (MMD) can be an underlying cause of Central Retinal Artery Occlusion (CRAO), even in young individuals.
  • Ocular manifestations like CRAO should be considered in the spectrum of Moyamoya disease complications.
  • Further research is warranted to understand the pathophysiology and incidence of CRAO in MMD patients.

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

Transient 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...

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

Ischemic Stroke l: Introduction

Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
