- The main result procedure was the newbie encounter medical diagnosis of uveitis utilizing medical diagnosis codes for iridocyclitis, undefined choroidal swelling, posterior cyclitis, choroidal degeneration, retinal vasculitis, and pan-uveitis.
TAKEAWAY:
- Electronic cigarette users had a considerably greater danger for establishing uveitis than nonusers (risk ratio [HR]2.53; 95% CI, 2.33-2.76 ), for iridocyclitis (HR, 2.59), undefined chorioretinal swelling (HR, 2.34), and retinal vasculitis (HR, 1.95).
- This increased threat for uveitis was observed throughout any age groups, impacting all genders and clients from Asian, Black or African American, and White ethnic backgrounds.

CONSTRAINTS:
The retrospective nature of the research study restricted the decision of direct causality in between electronic cigarette usage and the threat for uveitis. The research study did not have details on the period and amount of electronic cigarette direct exposure, which might have affected the findings. Scientists might not separate the impact of secondhand direct exposure to vaping or conventional cigarettes.
