RESUMEN
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. CONCLUSION: 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.
