Hypopyon uveitis, an eye inflammation, is most commonly linked to HLA B27-positive conditions like Reiter's syndrome and ankylosing spondylitis. Most patients with hypopyon uveitis test positive for HLA B27.

Area of Science:

  • Ophthalmology
  • Immunology
  • Rheumatology

Background:

  • Anterior uveitis is inflammation of the eye's front segment.
  • Hypopyon, a collection of white blood cells in the anterior chamber, is a sign of ocular inflammation.

Purpose of the Study:

  • To determine the incidence of hypopyon in anterior uveitis.
  • To identify common causes of hypopyon-associated anterior uveitis.

Main Methods:

  • Retrospective study of 216 patients with anterior uveitis.
  • Analysis of hypopyon incidence and association with HLA B27 status and systemic diseases.

Main Results:

  • 11 out of 155 (7.1%) patients with acute anterior uveitis presented with hypopyon.
  • Nine of 11 hypopyon patients were HLA B27-positive, with diagnoses including Reiter's syndrome and ankylosing spondylitis.

  • Incidence of hypopyon uveitis was significantly higher in HLA B27-positive patients (14.5%) compared to HLA B27-negative patients (2.2%).

    • Conclusions:

    • HLA B27-related anterior uveitis is the most frequent cause of hypopyon uveitis.
    • Most patients with hypopyon uveitis are expected to be HLA B27-positive.
    • Findings aid in the diagnosis and management of anterior uveitis with hypopyon.
