Research status and prospect of subthreshold diode micropulse laser in the treatment of central serous chorioretinopathy / 中华实验眼科杂志

ABSTRACT

Central serous chorioretinopathy (CSC) is a primary disease that affects the vision of young and middle-aged people.Its treatment is difficult because of its high incidence and easy recurrence.Currently, the commonly used clinical treatment methods for CSC include photodynamic therapy, traditional laser photocoagulation, subthreshold micropulse laser photocoagulation (SDM), anti-vascular endothelial growth factor therapy, and so on.SDM is a high-frequency, short, subthreshold and selective laser, which is preferred by many clinicians because of its low energy, good safety, small trauma and so on.Different wavelengths of laser can be absorbed by different pigments in the eye, so the therapeutic wavelengths of SDM for different sites of CSC are also different.In SDM treatment, it is necessary to determine the effective treatment range and parameters to avoid undertreatment or overtreatment.In this article, the mechanism of SDM in the treatment of CSC, the difference of SDM under different wavelengths, the selection of treatment site and parameters, the efficacy and safety were reviewed, and the prospect of SDM in the future was envisioned.
