Abstract

Purpose:: To investigate the relation between outpatient admission and pollenation patterns in patients with seasonal allergies.

Methods:: Meterological data in Chiba city, Kanto District, Japan were obtained in relation to wind, pollen type, scatter patterns and pollen volume from Tokyo Meterology Agency during 16/1/2006 and 28/4/2006. We then analyzed the relation of these parameters with the presentation patterns and status of allergic disease in patients with seasonal allergic conjunctivitis who visited Ajisai Eye Clinic during the same period. Only seasonal allergic conjunctivitis patients were included in the study. Subjects underwent questionnaires which inquiried about the degree of itching, onset of allergy during the previous year, ear and eye symptomatology, status of ENT, allergy check up and concurrent therapies. All subjects underwent a careful examination of the slit lamp findings.

Results:: Seventy-one patients were enrolled in this study. (Males:26 Females:45 age range:8~75 years Mean: 41.9±21.5 years) Outpatient admissions and clinical disease aggravation showed a close correlation with the pollen surge and weather data with significant aggravation of the clinical findings the day following the initial pollen surge which was dominated by cedar tree pollens. Only a few patients visited the clinic a month after the initial seasonal pollen surge even though the atmospheric pollen level remained persistently high. The main patient complaint at admission was itchy eyes in all patients. Eye symptomatology was predominant in 61.7% of the patients, ENT symptoms were seen in 25.1% and both symptoms were encountered in 13.2%. Thirty % of patients visited ENT clinic at the same time with their ophthalmology visit. Three patients used over the counter non anti-allergy medications before their visit.

Conclusions:: A detailed knowledge of pollen surge, type and weather patterns as well as pre-seasonal treatment for allergic patients was thought to be useful and effective in reducing allergic symptoms during pollen seasons.
