Abstract
Purpose
The purpose of this prospective study was to predict the effectiveness of subthreshold micropulse laser (SML) based on morphological parameters in patients with central serous chorioretinopathy (CSC).
Methods
Thirty-one patients were examined at presentation, 3 months, and 6 months after the disease onset. In patients with persistent subretinal fluid (SRF) at 3 months, SML was performed. The following morphological parameters were observed just before treatment: central retinal thickness (CRT), maximal SRF, choroidal thickness (CT), pigment epithelial detachment (PED) height and width, number of hyperreflective foci (HF) at fovea and leakage site, secondary choroidal neovascularization (CNV), and severity of retinal pigment epithelium (RPE) alterations using multimodal imaging.
Results
Good response was associated with lower SRF (p = 0.038), narrower PED (p = 0.078), and decreasing number of HF at fovea (difHFf) (p = 0 .016) just before the treatment. From a bivariate and multivariate point of view, the two groups differed significantly in the pair (SRF, PED width) (p = 0.048) and in the triple (SRF, PED width, difHFf) (p = 0.026).
Conclusion
Lower SRF, narrower PED, and decreasing HF could be associated with good response to SML in CSC patients.
