Acute zonal occult outer retinopathy (AZOOR) can present with variable symptoms and atypical features, complicating diagnosis. This case highlights the diagnostic challenges of this rare retinal condition.

Area of Science:

  • Ophthalmology
  • Retinal Diseases
  • Visual Electrophysiology

Background:

  • Acute zonal occult outer retinopathy (AZOOR) is a rare condition affecting the outer retina.
  • Early diagnosis can be challenging due to variable symptoms and lack of characteristic fundus findings.

Observation:

  • A 10-year-old boy presented with a large temporal scotoma and photopsia.
  • Initial fundus examination was normal, but visual field testing revealed a significant defect.
  • Electroretinography (ERG) became nonrecordable, and RPE atrophy developed over time.

Findings:

  • The case demonstrates a typical presentation of AZOOR with persistent visual field defects and ERG abnormalities.
  • Development of sharply demarcated retinal pigment epithelium (RPE) atrophy was noted.

  • The diagnostic difficulty associated with AZOOR's variable presentation is emphasized.

    • Implications:

    • This case underscores the importance of considering AZOOR in patients with unexplained visual field loss and electroretinography abnormalities.
    • Recognizing the diverse clinical manifestations of AZOOR is crucial for timely diagnosis and management.
    • Further research into AZOOR's pathogenesis and diagnostic markers may improve patient outcomes.
