Summary

Central serous chorioretinopathy (CSC) is a relatively frequent eye disease in younger patients. It is characterized by serous detachment of the neurosensory retina with or without serous detachment of the retinal pigment epithelium (RPE), which can cause vision drop, image distortion, loss of color and contrast vision. Although nonfoveal focal leakage can be treated with traditional laser photocoagulation, but it has the side effects of causing RPE atrophy, scotoma, or secondary CNV. Photodynamic therapy (PDT) is another effective treatment but it's more than most families can afford to pay because of the high cost, what's more, it is accompanied with side-effects, such as choroidal ischemia, retinal pigmental epithelium (RPE) atrophy and RPE rip.

To date there is no international consensus on the optimal treatment of CSC Many retrospective studies suggest that micropulse laser (MPL) therapy may also be effective without obvious complications in this disease.

The purpose of this study is to evaluate the effect of micropulse laser (MPL) on acute central serous chorioretinopathy compared with the traditional laser coagulation.

Conditions

  • Acute Central Serous Chorioretinopathy

Interventions

DEVICE

577-MPL

All treatments were provided by a single practitioner with the 577-nm yellow laser system(Supra 577nm affected area in micropulse model.The power titration was started at 700 milliwatt(mW) and then gradually increased until a just visible burn was seen. When this threshold was reached, the power was reduced by 50%, using a 100-μm spot diameter and a 200-ms duration with 5 % duty cycle LaserSystem) in 577-MPL arm. The individual power for the patient was titrated at a normal area of near the

DEVICE
