Uveitis Associated with Conventional Cigarette Smoking and E-Cigarette Use: A Narrative Review

Background and Objectives: Uveitis is an inflammatory condition of the uveal tract and has been associated with cigarette smoking. However, the relationship between uveitis and electronic cigarette (e-cigarette) use remains poorly understood. This review aims to give a brief overview of the current evidence regarding the association between uveitis and both conventional cigarette smoking and e-cigarette use. Materials and Methods: A narrative literature review was conducted using PubMed and Scopus databases. Relevant peer-reviewed publications were identified using the search terms "vaping," "cigarette," and "uveitis." Results: Multiple studies have demonstrated a significant association between cigarette smoking and an increased risk of uveitis. In contrast, evidence examining the relationship between e-cigarette use and uveitis is limited. Conclusions: Uveitis is a potentially vision-threatening ophthalmologic condition, and improved understanding of its risk factors is essential for optimal patient care. While the association between conventional cigarette smoking and uveitis is well established, current evidence regarding e-cigarette use remains insufficient. Further research is needed to clarify the potential role of e-cigarette use in the development of uveitis.
