title: [Clinical study of diabetic retinopathy treated by compound danshen dripping pills].
abstract: OBJECTIVE
  To observe the therapeutic effect of compound danshen dripping pills in visual function recovery of diabetic retinopathy.
  
  
  METHODS
  42 patients(78 eyes) with diabetic retinopathy of I-III phase were divided into two groups in random. 43 eyes were treated with compound danshen dripping pills and the other 35 eyes with vitamin BI and Luding C for three months. The visual acuity, fundus, visual field, fundus fluorescein angiography and visual electro-physiology were observed.
  
  
  RESULTS
  The visual acuity in treated group were significantly improved after treatment and had significant difference with those in control group (P < 0.05). The number of micro-hemorrage, microaneurysm and the mean defect (MD) of visual field in treated group decreased obviously after treatment and had significant difference with that in control group (P < 0.05). The latent period of P100 wave and a, b wave in treated group were shorter than control group, and the wave amplitude were higher than that in control group.
  
  
  CONCLUSIONS
  The compound danshen dripping pills can improve the visual acuity, control the micro-hemorrage and microaneurysm of fundus and have the effect in visual function recovery of diabetic retinopathy.
