Clinical Observation of Yangyin Qingfei Decoction for Xerophthalmia Patients with Syndrome Pattern of Deficiency of Lung-yin

Objective:To observe the effect of Yangyin Qingfei Decoction for xerophthalmia patients with the syndrome pattern of deficiency of lung-yin.Methods:Sixty patients with xerophthalmia were equally randomized into the treatment group,which was treated with Yangyin Qingfei Decoction combined with artificial tears,and the control group,treated with artificial tears alone.The Schirmer test(SIT),break up time(BUT) of tear film,corneal fluorescein staining(FL) were used to evaluate the therapeutic effect in two group.Results:After treatment,the SIT secretion and BUT of the treatment group were significantly higher than those before treatment(P 0.05).The difference of SIT and BUT between two groups was also significant(P 0.05)after treatment,and the improvement in the treatment group was superior to that in the control group.After treatment the score of FL in the treatment group was decreased significantly(P 0.05 compared with that before treatment).While the difference between the two groups was not significant(P 0.05)after treatment.The total effective rate in the treatment group was 76.7%,and was 50.0% in the control group,the difference being significant(P 0.05).Conclusion:Yangyin Qingfei Decoction combined with artificial tears has better curative effect than artificial tears alone in treating xerophthalmia patients with the pattern of deficiency of lung-yin.
