This case report details a rare central retinal artery obstruction with unusual artery sparing. Recognizing this variation is crucial for accurate diagnosis and management of retinal artery occlusions.

Area of Science:

  • Ophthalmology
  • Vascular Neurology

Background:

  • Central retinal artery obstruction (CRAO) is a critical condition leading to vision loss.
  • Typical CRAO involves a complete blockage of the central retinal artery.

Observation:

  • This report describes a unique embolic CRAO affecting three-fourths of the artery.
  • Notably, the superior temporal branch artery was spared, along with multiple nonfoveolar-sparing cilioretinal arteries.

Findings:

  • The unusual pattern of obstruction mimicked ischemic optic neuropathy after a five-month delay.
  • This atypical presentation highlights potential diagnostic challenges.

Implications:

  • Misdiagnosis and incorrect management can occur in patients with CRAO if this variation is not recognized.

  • Awareness of such anatomical variations is vital for ophthalmologists and neurologists managing retinal vascular events.
