The study compared the application of FA and ICGA in imaging CSC patients, showing consistent leakage points between FA and ICGA, but differences in leakage size and chronicity. This suggests that FA could be considered an alternative ocular imaging technology for guiding PDT in CSC patients.
Purpose. - To compare fluorescein angiography (FA) and indocyanine green angiography (ICGA) for imaging of central serous chorioretinopathy (CSC) patients. Methods. - The observational cross-sectional clinical study was conducted on 131 eyes of 131 patients with CSC who were candidates for photodynamic therapy (PDT). An experienced ophthalmologist marked the leakage sites and choroidal hyperpermeability sites that needed PDT. For each eye, simultaneous FA and ICGA imaging with the maximum leakage area was selected for comparison regarding the site and size. Results. - The mean +/- standard deviation age of patients was 44.53 +/- 9.03 years. Of 226 leakage points, 177 (78.32%) points were in the same site, and 168 (74.34%) points were in the same size on FA. No statistical difference was found between age (P= 0.45), sex (P= 0.32), and chronicity (P= 0.11) of the disease in comparing the ICGA images to the FA images regarding leakage at the same site. A statistically significant difference was also found regarding size of leakage and chronicity (P < 0.001). Conclusion. - The current results suggested that FA could be considered an alternative ocular imaging technology as a guide for PDT in CSC patients. (C) 2021 Published by Elsevier Masson SAS.
