[How to face the new classification of primary angle closure glaucoma]

Area of Science:

• Ophthalmology
• Glaucoma Research
• Clinical Classification Systems

Background:

• A novel international classification system categorizes angle closure and related risk factors into anatomic narrow angle, primary angle closure, and primary angle closure glaucoma (PACG).
• This new system presents a significant divergence from the long-established traditional PACG classification used in China.
• The discrepancy necessitates a thorough evaluation rather than outright acceptance or rejection.

Discussion:

• The study emphasizes the need for a balanced approach to the new international PACG classification.
• It advocates for critical analysis to identify and incorporate its essential elements.
• The discussion highlights the importance of developing a nuanced perspective on PACG classification and diagnostic criteria.

Key Insights:

• The international system offers distinct categories for angle closure spectrum.
• Traditional Chinese classification for PACG requires re-evaluation in light of new international standards.
• A hybrid approach may be beneficial for refining PACG diagnosis and management.

Outlook:

• Further research should focus on comparative studies between the two classification systems.
• Clinical validation of the new system's impact on patient outcomes is crucial.
• International collaboration can refine diagnostic criteria for primary angle closure glaucoma globally.
