Objective:
To establish consensus definitions for retinal vasculitis and related vascular conditions.
Approach:
- Consensus Process: An international expert panel conducted a modified Delphi consensus study involving 27 specialists to address inconsistent terminology in retinal vasculitis, with two rounds of voting.
- Rating and Agreement: Participants rated statements on a 5-point Likert scale, achieving consensus on core definitions with agreement ranging from 83% to 96% in the first round and 95% to 100% in the second round.
Key Findings:
- Retinal vasculitis is defined as inflammation of retinal blood vessels with accompanying retinal damage.
- Vascular leakage alone is insufficient for diagnosing retinal vasculitis.
- The panel defined infectious and noninfectious retinal vasculitis, as well as primary retinal vasculitis and retinal perivasculitis.
- Retinal vasculopathy is characterized by vascular abnormalities not resulting from retinal vasculitis.
Interpretation:
The consensus framework emphasizes the need for clinical evidence of intraocular inflammation and retinal damage for diagnosing retinal vasculitis.
Limitations:
- Definitions are based on expert consensus rather than empirical validation.
- Distinguishing retinal vasculitis from other conditions may remain challenging, especially early in the disease.
Conclusion:
Standardized terminology could facilitate clearer communication in clinical settings.
