Self-Reported Red Eye Among Saudi Adults: Symptom Profile, Self-Management Practices, and Associated Factors

Background/Objectives: Red eye is a common ocular complaint, yet population data from Saudi Arabia are limited and largely confined to specific diagnostic entities. This study assessed the proportion of adults reporting red eye and described its clinical characteristics, perceived triggers, management practices, and associated factors.

Methods

A cross-sectional survey was conducted between November 2025 and March 2026 among adults aged 18 years or older in Saudi Arabia, recruited by convenience sampling through social media. A structured self-administered questionnaire captured sociodemographic, systemic, ocular, and lifestyle characteristics and, among affected participants, symptom profile, triggers, and management. The outcome was ascertained with a single screening item, accompanied by a photograph to aid recognition, asking whether participants currently had, or had previously had, red eye. Multivariable logistic regression identified independently associated factors (p < 0.05).
