Summary

Giant cell arteritis (GCA) can cause blindness, but prompt steroid treatment improves vision. Intravenous steroids may be more effective than oral steroids for treating GCA-related vision loss.

Area of Science:

  • Ophthalmology
  • Rheumatology
  • Vascular Medicine

Background:

  • Giant cell arteritis (GCA) is a medical emergency with potential for irreversible vision loss.
  • Current steroid treatment protocols for acute GCA lack robust evidence.
  • Ocular complications, particularly anterior ischemic optic neuropathy (AION), are a major concern in GCA.

Purpose of the Study:

  • To review the effectiveness of intravenous (IV) and oral steroid treatments for GCA.
  • To analyze treatment outcomes, including visual acuity changes and complications, in patients with GCA and visual loss.

Main Methods:

  • Retrospective review of 100 patients with biopsy-proven GCA.
  • Inclusion of 73 patients with visual loss treated at two hospitals.
  • Analysis of treatment type, dosage, visual acuity response, and complications within the first week of presentation.

Main Results:

  • Anterior ischemic optic neuropathy (AION) was the primary cause of visual loss in 99% of patients.
  • Visual acuity improved in 29% of patients after steroid initiation.
  • Intravenous steroids showed a higher rate of visual improvement (40%) compared to oral steroids (13%).

Conclusions:

  • Early steroid administration in GCA can significantly improve visual acuity.
  • Intravenous steroids may offer a better prognosis for vision recovery than oral steroids.
  • Further prospective studies are warranted to compare IV and oral steroid efficacy in GCA.
