Clinical characteristics of allergic conjunctivitis in the Southern region of Saudi Arabia: a cross-sectional study.

BACKGROUND

Allergic conjunctivitis is a prevalent ocular condition characterized by inflammation of the conjunctiva due to hypersensitivity reactions to various allergens. Understanding its epidemiology and clinical characteristics is crucial for effective management and public health interventions.

METHODS

This cross-sectional study investigated the prevalence, triggers, and associated factors of allergic conjunctivitis among residents of the Southern region of Saudi Arabia. Data were collected using a structured questionnaire administered through Google Forms. Statistical analysis was performed using IBM SPSS, including descriptive statistics and bivariable/multivariable analyses.

RESULTS

A total of 693 participants were recruited through convenience sampling via online platforms. Among the participants, 73.9% reported ocular symptoms, while 26.1% did not. Dust emerged as the most common trigger for ocular symptoms (32.9%), followed by eye drops/contact lenses (8.7%), animal dander (6.9%), and chemicals (5.8%). Notably, 39.7% reported experiencing ocular symptoms throughout the year. Despite the prevalence of ocular symptoms, only 26.7% consulted an ophthalmologist. Multivariable analysis revealed that gender and seasonal variation in symptoms were associated with allergic conjunctivitis diagnosis. Females showed a lower odds ratio (OR) of being diagnosed with allergic conjunctivitis compared to males (OR: 0.62, 95% CI: 0.29-1.31), and participants experiencing symptoms with no specific season had significantly lower odds of being diagnosed with allergic conjunctivitis (OR: 0.28, 95% CI: 0.11-0.72). A history of allergic rhinitis demonstrated a strong positive association with allergic conjunctivitis diagnosis (OR: 3.77, 95% CI: 1.83-7.75).

CONCLUSION

The study highlights the considerable burden of allergic conjunctivitis and the underutilization of healthcare services among affected individuals in the Southern region of Saudi Arabia. Tailored interventions and increased awareness are essential for effective management and mitigation of allergic conjunctivitis's impact on affected individuals and healthcare systems.
