RESUMO
[Objective] To evaluate the effect of Ginkgo biloba extract on optic nerve in progressive normal-tension glaucoma patients. [Methods] 60 cases of patients suffered from controlled normal-tension glaucoma were randomly divided into control and treatment groups, 30 cases in each respectively. The patients in the control group received the conventional treatment(eye drops or surgical treatment), additionally the patients in the treatment group received Ginkgo biloba extract(twice a day ,1ml each time). 5 months was a therapeutic course, after 3 therapeutic courses the best corrected visual acuity, ocular hemodynamics, visual field, retinal nerve fiber layer thickness and optic disc data were detected and statistically studied. [Results] There was no significant difference in the best corrected visual acuity between control group and treatment group( P>0.05). The end diastolic velocity(EDV), peak systolic velocity(PSV) were increased significantly and resistive index(RI) was decreased significantly in treatment group after treatment( P<0.05), while the EDV, PSA, RI in control group before and after treatment were without significant differences( P>0.05). The mean visual field defects(MD) in treatment group after treatment were much lower than the control group( P<0.05). The reduction trends of the retinal nerve fiber layer thickness and rim area in treatment group after treatment were slower than control group significantly decreased( P<0.05). [Conclusion] Ginkgo biloba extract can improve the ocular hemodynamics, delay the deterioration of the best corrected visual acuity and visual field damage, extend the losing time of visual retinal nerve fiber layer thickness and rim area. It has protective effect on optic nerve in normal-tension glaucoma.
RESUMO
[Objective] To observe the clinical efficacy of treatment on Frequent Postoperative Posner-Schlossmann syndrome in cataract intraocular lens using Chinese medicine with the effect of tonifying the liver and kidney, nourishing yin and suppressing hyperactive yang.[Methods] 46 cases of Posner-Schlossmann syndrome were randomly divided into two groups, one was the Chinese Medicine group ,in which al cases were treated with Chinese herbs and local eyedrop at the time of first onset after operation; another was the control group, in which al cases were treated with local eyedrop. [Results] Within two years after treatment, compared with the control, in the Chinese Medicine group, the cases of recurrence of Posner-Schlossmann syndrome were obviously decreased. [Conclusion] Chinese medicine with the effect of tonifying the liver and kidney, nourishing yin and suppressing hyperactive yang shows definite effect on postoperative Posner-Schlossmann syndrome, it can decrease the occurrence frequency of number.
