Brief Summary:
To determine changes in retinal and choroidal capillaries with optical coherence tomographic angiography (OCTA) after half-dose photodynamic therapy (hd-PDT) in eyes with central serous chorioretinopathy (CSC).
Detailed Description:
PDT was hypothesized to have a primary effect on the choroidal capillaries, and a number of studies have reported choriocapillary damage and choroidal vascular remodeling after PDT. More recently, although OCTA related CSC research has been conducted, no quantitative report has thoroughly investigated the microstructural changes in the superficial, deep retinal and choroidal capillaries after hd-PDT. The purpose of the present study is to determine the changes in the retinal and choroidal capillaries quantitatively with OCTA after hd-PDT in eyes with CSC.
This is a prospective observational study of patients undergoing hd-PDT for CSC with active leakage in retinal pigment epithelium (RPE) and followed for 3 months. Fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were performed at baseline; best corrected visual acuity (BCVA), fundus photography, optical coherence tomography angiography (OCTA) with the split-spectrum amplitude-decorrelation angiography algorithm (XR Optovue, Fremont, CA, USA) and spectral domain OCT (SD-OCT) were performed at baseline and each follow-up visit after hd-PDT.
