ObjectiveTo evaluate the effects of Fufang Xueshuantong combined with laser photocoagulation versus laser photocoagulation alone in the treatment of diabetic retinopathy (DR).
MethodThe Web of Science, Medline, Embase, the Cochrane Library, China Biology Medicine disc, China National Knowledge Infrastructure, VIP and Wanfang databases were searched from their establishment until June 2015. We used the method recommended by the Cochrane Collaboration to perform a meta-analysis of randomized controlled trails. RevMan 5.2 software was used for the analysis.
ResultsEight studies were included. The results of Meta-analysis demonstrated that Fufang Xueshuantong combined with laser photocoagulation was superior to laser photocoagulation alone in the effective rate of visual acuity[RR=1.19, 95%CI (1.12, 1.26), P<0.000 01], fundus[RR=1.34, 95%CI (1.18, 1.52), P<0.000 01], and elimination rate of macular edema[RR=1.29,95%CI(1.09,1.54),P=0.004].
ConclusionsFufang Xueshuantong combined with laser photocoagulation is effective for DR. However, due to the limited quantity and quality of the included studies, the results suggest that larger-scale trials are needed.
The effect and opportunity of argon laser photocoagulation for the retinal neovascularization in branch retinal vein occlusion in 30 patients were investigated with a control group of 34 patients received nonlaser but routine treatment. The results of the therapeutic effect demonstrated that the neovascularization disappeared completely in 23 cases and became smaller in 7 cases after laser photocoagulation. The incidnce of vitreous hemorrhage in laser group was 43.3% before laser treatment and none after treatment in the duration of observation,and 70.6% in control group. The progression of visual acuity after treatment in laser group was much better than in control group(P＜0. 005)at the time of the latest examination. We found the therapeutic effect was relation to the area, location of the neovascularization in retina,as well as whether the new vessels protruding into vitreous or not.
