Summary
The Zhang system for diagnosing conjunctivochalasis showed a lower prevalence (39.01%) compared to Meller's system (72.89%). Zhang's system better aligns with patient treatment preferences and medical interventions for conjunctivochalasis.
Area of Science:
- Ophthalmology
- Public Health
Background:
- Conjunctivochalasis diagnosis and grading systems vary, leading to discrepancies in prevalence rates.
- This study compares Meller's 4-level system and Zhang's modified 5-level system for conjunctivochalasis diagnosis.
Purpose of the Study:
- To investigate the disparity in conjunctivochalasis diagnosis between Meller's and Zhang's systems.
- To assess patient preferences for conjunctivochalasis treatment based on diagnostic system.
Main Methods:
- 546 elderly residents in Shanghai, China, were evaluated using both Meller's and Zhang's diagnostic systems.
- Patient treatment preferences were recorded, and surgical interventions were tracked over one year.
Main Results:
- Meller's system identified conjunctivochalasis in 72.89% (398 participants), while Zhang's system identified it in 39.01% (213 participants).
- Treatment decisions, including surgery, were more aligned with diagnoses from Zhang's system, particularly for lower-grade cases.
Conclusions:
- Zhang's system provides a more accurate reflection of patient needs and treatment strategies for conjunctivochalasis.
- The study highlights the importance of standardized diagnostic criteria for conjunctivochalasis prevalence and management.
