Atypical visual loss in giant cell arteritis

Summary

Giant cell arteritis (GCA) can present with unusual ocular and neurological symptoms. Early diagnosis and treatment are crucial, but even then, severe visual loss can occur in patients with GCA.

Area of Science:

  • Ophthalmology
  • Neurology
  • Rheumatology

Background:

  • Giant cell arteritis (GCA) is a systemic vasculitis affecting medium and large arteries.
  • Ocular involvement is a common and serious complication of GCA, potentially leading to irreversible vision loss.

Observation:

  • This report details three patients with histologically confirmed GCA and atypical ocular manifestations.
  • Case 1: Experienced amaurosis fugax, presented with normal vision, but ultimately suffered bilateral occipital cortex infarctions and blindness despite corticosteroid treatment.
  • Case 2: Presented with unilateral visual loss and cotton-wool exudates; central vision recovered with corticosteroids, an unusual outcome.
  • Case 3: Exhibited irreversible unilateral visual loss typical of GCA, complicated by an unusual association with polyneuropathy.

Findings:

  • The cases highlight the diverse and sometimes severe neurological and visual complications of GCA.
  • Autopsy in Case 1 confirmed intracranial artery involvement, explaining the infarctions.
  • Neurological remission was observed in Case 3 concurrently with systemic corticosteroid therapy.

Implications:

  • These cases underscore the importance of considering GCA in patients with unexplained visual and neurological deficits.
  • The varied presentations emphasize the need for vigilant monitoring and tailored treatment strategies in GCA management.
  • Further research into the specific mechanisms of ocular and neurological damage in GCA is warranted.
