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

Figure 3

Spectral domain optical coherence tomography (SD-OCT), fundus autofluorescence (FAF), and fluorescein angiography (FA) images of a 47-year-old female patient with CSC for 7 months. Left eye before photodynamic therapy (PDT): chronic subretinal fluid on SD-OCT (a), hypoautofluorescence on FAF image due to the blockage effect of the subretinal fluid (b), and focal leakage of fluorescein and two small pigment epithelial detachments at the late phase of FA (c). Eight months after PDT treatment: complete resolution of the subretinal fluid (d) and disappearance of hypoautofluorescence on FAF (e).
