Clinical study ofQiju-Dihuang decoction combined with tears naturale on dry eye of liver and kidney

Abstract

Objective To investigate the clinical effect ofQiju-Dihuang decoction combined with tears naturale（hypromellose 2910,dextran 70 and glycerol eye drops）on dry eye of liver and kidneyYin deficiency patterns.Methods Sixty patients with dry eye in Fangxian People’s Hospital and Fangxian Hospital of TCM from Jan. 2010 to Aug. 2013 were divided into a control group（30 patients）and a treatment group（30 patients） randomly according to registration order. The patients in the control group were treated with tears naturale, while patients in the treatment group were additionally treated withQiju-Dihuang decoction orally on the basis of the control group. Both groups were treated for 8 weeks. After treatment, the clinical symptoms and signs were compared and the changes of breakup time of tear film（BUT）, Schirmer test I（S1T）and corneal fluorescein staining（FL）score were measured in both groups.Results The total effective rates in the treatment group and in the control group were 73.33%（22/30）and 46.67%（14/30）, respectively. The difference was statistically significant（χ2=4.44,P〈0.05）. After treatment, the BUT, S1T and FL score of the treatment group and the control group was significantly improved than those before in both groups（t=4.200, 4.374, 9.098, 2.147, 6.627,P〈0.05 orP〈0.01）, and the degrees of BUT, S1T score increased and FL score decreased in the treatment group were superior to those in the control group（t=2.75, 2.43, 3.05,P〈0.05 orP〈0.01）. ConclusionsQiju-Dihuang decoction combined with tears naturale can obviously improve dry eye of liver and kidneyYin deficiency patterns, increase tear secretion, and reduce the damage of canthus and conjunctiva. Its curative effect was superior to simple tears naturale. Key words: Dry Eye Syndromes; Qiju-Dihuang decoction; Artificial tears; Clinical study
