Prevalence of ocular symptoms in patients with allergic rhinitis: Korean multicenter study.

BACKGROUND: Allergic rhinitis (AR) is often accompanied by multiple ocular symptoms. This study aimed to evaluate the prevalence of ocular symptoms and the impact of ocular symptoms on the quality of life in patients with AR. METHODS: One thousand one hundred seventy-four patients with AR were enrolled from 24 centers in Korea. They were classified into four groups according to the Allergic Rhinitis and Its Impact on Asthma (ARIA) guideline and also classified into perennial AR (PAR) and seasonal AR groups. All patients were asked to complete the questionnaire regarding the presence of ocular symptoms, such as eye itching, watery eyes, and red eyes. The correlation between ocular symptoms and the rest of the quality-of-life areas in the Mini-Rhinoconjunctivitis Quality of Life Questionnaire (Mini-RQLQ) was also asked. RESULTS: Seven hundred nineteen (61.2%) of 1174 patients had ocular symptoms. In detail, the numbers of patients with eye itching, watery eyes, red eyes, and other ocular symptoms were 605 (51.5%), 313 (26.7%), 207 (17.6%), and 66 (5.6%), respectively. Female patients (72.5%) complained of ocular symptoms more commonly than male patients (55.1%). The patients with moderate-severe persistent AR showed the highest prevalence of ocular symptoms. The correlation coefficients between ocular symptoms and the rest of the quality-of-life areas in the Mini-RQLQ were statistically significant (p < 0.05). CONCLUSION: Sixty-one percent of Korean AR patients experienced ocular symptoms. The patients who were women and had PAR and more severe AR showed higher prevalence of ocular symptoms. The ocular symptoms might have a significant impact on the quality of life in patients with AR.
