Arachnoid cysts rarely cause ocular symptoms. This case highlights a young man with peripheral vision loss due to optic nerve compression from an arachnoid cyst.

Area of Science:

  • Neuroscience
  • Ophthalmology
  • Neurology

Background:

  • Arachnoid cysts are typically asymptomatic, arising from the arachnoid mater, a membrane surrounding the brain and spinal cord.
  • Ocular manifestations of arachnoid cysts are uncommon, making such presentations diagnostically challenging.

Observation:

  • A young male patient presented with unilateral peripheral field contraction as his sole initial symptom.
  • Diagnostic imaging confirmed the presence of an arachnoid cyst.

Findings:

  • The arachnoid cyst was identified as the pathogenic cause of the patient's visual field defect.
  • The cyst exerted direct compression on the optic nerve, leading to the observed ocular symptoms.

Implications:

  • This case underscores the importance of considering arachnoid cysts in the differential diagnosis of unexplained visual field defects.
  • Early diagnosis and management of optic nerve compression by arachnoid cysts are crucial for preserving vision.
