    Essential iris atrophy can manifest with late-stage iris nodules. These nodules, initially yellow, progress to dark brown, aiding differential diagnosis.

    Area of Science:

    • Ophthalmology
    • Genetics

    Background:

    • Essential iris atrophy (EIA) is a progressive degenerative disease affecting the iris.
    • Understanding the full spectrum of EIA manifestations is crucial for accurate diagnosis and management.

    Observation:

    • Seven cases of EIA exhibiting iris nodules are presented.
    • These nodules represent a previously undocumented feature of EIA.

    Findings:

    • Iris nodules appear late in the course of EIA.
    • Initially small and yellow, they increase in number and darken to brown over time.
    • The presence of multiple iris nodules requires differentiation from other conditions.

    Implications:

    • The identification of iris nodules expands the diagnostic criteria for essential iris atrophy.

  • This finding may prompt earlier or more accurate diagnosis in patients with EIA.
  • Further research is warranted to understand the pathogenesis of these nodules.
