摘要：PurposeTo evaluate the effect of photodynamic therapy (PDT) on central serous chorioretinopathy (CSC) compared with laser therapy and intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) drugs, and to find the maximum treatment effect with minimal dose and fluence of PDT.; MethodsA systematic electronic search was conducted in Feb 2013 in PubMed, Embase, ISI Web of Knowledge and the Cochrane library. The main outcome factors were compared in best-corrected visual acuity (BCVA), central macular thickness (CMT) and resolution of subretinal fluid (SRF). Meta-analysis was performed when it is appropriate. The comparisons were designed into four groups: group 1, PDT versus laser photocoagulation; group 2, PDT versus intravitreal injection of anti-VEGF drugs; group 3, half-dose verteporfin PDT versus placebo; group 4, half-fluence PDT versus full-fluence PDT.; ResultsWe retrieved nine reports of studies including a total of 319 patients. In group 1, the summary result indicated that PDT was superior in resolution of SRF (p=0.005) than laser photocoagulation. In group 2, PDT could resolute SRF (p=0.007) and decrease CMT (p=0.002) more rapidly than intravitreal injection of anti-VEGF drugs. In group 3, half-dose PDT was effective in improving BCVA (p<0.00001), decreasing CMT (p=0.001) and resolving SRF (p<0.001). In group 4, half-fluence PDT was effective and could significantly decrease the hypoxic damage which was caused by PDT (p<0.001).; ConclusionPDT is a promising therapy for CSC patients and the parameters of PDT can be adjusted to obtain the maximum treatment effect with minimal adverse effects.
