比较农村与城市２组春季卡他性结膜炎患者的过敏原皮试、血清ＩｇＥ水平，结果表明：２组过敏原皮试的阳性率及血清ＩｇＥ水平差异无显著性，但农村组皮试强阳性率明显高于城市组（Ｐ＜０．０１）；２组皮试均以蒿属花粉、春季花粉、螨、真菌等阳性反应占多数。对２组皮试阳性的患者作特异性脱敏治疗，结果是：农村组总有效率低于城市组（Ｐ＜０．０５）。提示农村与城市地理环境、气候、植被等差异对春季卡他性结膜炎可产生较大的影响。
The allergen skin test and serum IgE levels in two groups of spring catarrhal conjunctivitis patients in rural and urban areas were compared. The results showed that there was no significant difference between the two groups in allergen skin test and serum IgE level, but strong positive rate of skin test in rural group (P <0.01). The skin tests of Artemisia sp., Pollen, mites and fungi in the two groups accounted for the majority of positive reactions. Specific desensitization was performed on two skin-test positive patients. The overall response rate was lower in rural than in urban (P <0.05). It is suggested that the difference between rural and urban geography, climate and vegetation may have a great impact on catarrhal conjunctivitis in spring.
