AIM: To evaluate the efficacy of pseudo-ginseng power for post-vitrectomy vitreous hemorrhage in diabetic patients and provide new insight into the treatment options.

METHODS: Totally 32 eyes of 32 patients with post-vitrectomy hemorrhaged secondary to proliferative diabetic retinopathy were included. Patients were prescribed with pseudo-ginseng powered, 1.5g, twice a day, for 3 consecutive sections(21d). The visual acuity, optical coherence topography image quality and degree of vitreous hemorrhage was assessed before and after the treatment were analyzed to evaluate the efficacy of pseudo-ginseng powder.

RESULTS: No adverse reaction was seen in all subjects after 21d of treatment. And 88% of the patients had improved visual acuity. The mean best corrected visual acuity(LogMAR)was 1.93±0.46 and 1.42±0.5, before and after treatment, respectively. For the patients with visual acuity no worse than 0.02, finger counting to less than 0.02 and light perception, the improvement rate was 100%. For patients with visual acuity from hand motion, the improvement rate was 60%. The improvement rate for optical coherence tomography image quality was 94%, and 94% for degree of vitreous hemorrhage.

CONCLUSION: Pseudo-ginseng power is effective in patients with postvitrectomy hemorrhaged secondary to proliferative diabetic retinopathy. It accelerated the elimination of vitreous hemorrhage and improved the visual acuity as well as decreased the likelihood of re-cooperation.
