    Abstract： Objective: To investigate the effect of Ginkgo biloba extract on recovery of visual function after anti-glaucoma surgeries. Method: A total of 37 patients, who had undergone anti-glaucoma surgeries, was randomly selected and divided into treatment group and control group. The control group received vitamin treatments only. The treatment group received both vitamin and Ginkgo biloba extract at a dosage of one tablet three times per day for a period of three months. The difference in pathological changes was compared between two groups by recording both pre-treatment and post-treatment results including optimal visual acuity, visual field, eye pressure and P-VEP of all patients. Result: ①With respect to improvement of eyesight, there was no apparent difference between two groups in terms of enumeration data. Treatment group however significantly showed better result than control group in term of metric data; ②After treatment, the treatment group improved significantly in both visual field and P-VEP. Conclusion: Ginkgo biloba extract with a minor side effect is functional in protecting the optic nerve and improving visual function after glaucoma surgery. ......
