Summary
Chalazion incidence and treatment success are influenced by age and climate. Warmer temperatures correlate with higher chalazion prevalence, and age impacts the need for invasive procedures.
Area of Science:
- Ophthalmology
- Epidemiology
Background:
- Chalazia are common eyelid conditions with varying treatment outcomes.
- Understanding epidemiological patterns is crucial for effective management.
Purpose of the Study:
- To describe large-scale epidemiological patterns of chalazia.
- To assess the outcomes of different chalazion treatments.
Main Methods:
- Retrospective cohort study utilizing electronic medical records from January 2003 to December 2022.
- Analysis of demographic data, medical history, treatments, procedures, and outcomes for over 412,000 patients.
- Statistical analysis to determine treatment efficacy and influencing factors.
Main Results:
- Over 611,000 chalazion diagnoses were recorded.
- Invasive procedures were needed in 9.3% of cases.
- Topical therapies showed varied success rates, with lubricants being most conservative. Incidence strongly correlated with temperature (r=0.71, p<0.001), with higher prevalence above 21°C.
- Invasive intervention rates increased with age (1.8% <18 years, 13.7% >45 years).
Conclusions:
- Most chalazia resolve with conservative management.
- Age and climate are significant factors influencing chalazion incidence and treatment outcomes.
- Findings suggest tailored management strategies based on environmental and demographic factors.
