春季カタルの臨床像の最近5年間における推移

Changing trends in the clinical feature of vernal keratoconjunctivitis in the past five years

要約　目的：免疫抑制薬が使用されるようになった過去5年間の春季カタルの臨床像の報告。対象と方法：2012年までの5年間に春季カタルと診断した64例を対象とした。男性53例，女性11例で，年齢は3～34歳，平均12歳であった。診療録の記述を検索した。結果：年齢は5～9歳，病型は眼瞼型，受診率は5～9月に多かった。アトピー性皮膚炎は45例（70％）にあった。検索した5年間の受診者と初診時の重症度は，減少する傾向にあり，女性の割合は増加した。ほぼ全例に免疫抑制点眼薬が用いられ，ステロイド薬の点眼は減少する傾向があった。結論：春季カタルの受診者数は過去5年間に減少し，軽症化する傾向があり，本症の発症原因が変化している可能性がある。

Abstract.　Purpose：To present a review of vernal keratoconjunctivitis in the past 5 years. Cases and Method：This retrospective study was made on 64 cases of vernal keratoconjunctivitis seen by us during 5 years through 2012. The series comprised 53 males and 11 females. The age ranged from 3 to 34 years, average 12 years. This study was based on the clinical record. Results：The age at the initial visit was most frequent from 5 to 9 years. Eyelid type was the most frequent. The incidence showed a peak from May to September. Atopic dermatitis was present in 45 cases（70％）. There was a tendency for the number of patients and the severity to decrease during the 5-year period. Female patients showed a tendency to increase. Almost all the cases had been treated by topical immunosuppressive drugs. Corticosteroid eyedrops showed a tendency to decrease. Conclusion：There was a tendency for the number of patients with vernal keratoconjunctivitis to decrease and its severity to decrease in the past 5 years. The findings seemed to suggest changes in its pathogenesis.
