Central serous chorioretinopathy (CSC) is characterized by serous detachment of neurosensory retina which can cause lose in visual acuity. Some studies have shown that traditional laser treatment (TLT) is effective on CSC, although accompanied with side-effects, such as scar. Recent retrospective studies suggest micropulse laser (MPL) therapy may also be effective without obvious complications in this disease. But to date, there is no study on effectiveness of CSC between TLT and MPL.
