Low-Fluence Photodynamic Therapy versus Subthreshold Micropulse Yellow Wavelength Laser in the Treatment of Chronic Central Serous Chorioretinopathy

Figure 4

Spectral domain optical coherence tomography (SD-OCT), fundus autofluorescence (FAF), and fluorescein angiography (FA) images of a 42-year-old female patient with CSC for 7 months. Left eye before subthreshold micropulse yellow wavelength laser (SMYL) treatment: chronic subretinal fluid with fibrin accumulation on SD-OCT (a), increased hypoautofluorescence on FAF image due to the blockage effect of the subretinal fluid (b), and focal leakage of fluorescein at the late phase of FA (c). Nine months after SMYL treatment: complete resolution of the subretinal fluid (d) and hypoautofluorescence spots due to RPE atrophies at the previous leakage area on FAF (e).
