Quantitative Evaluation of Damages to Retinal Capillaries Caused by Half-dose and Half-time Photodynamic Therapy with Optical Coherent Tomographic Angiography
Purpose : To determine and compare retinal capillaries damages in patients with chronic central serous chorioretinopathy (CSC) after half-dose and half-time photodynamic therapy (PDT) based on optical coherence tomographic angiography (OCTA). Methods : Thirty-three eyes of 33 patients and 32 eyes of 32 patients with active CSC were treated with half-dose PDT and half-time PDT respectively and followed up for 3 months. Fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were performed at baseline; best corrected visual acuity (BCVA) and OCTA were performed at baseline, 3-day, 7-day, 14-day, 1-month, and 3-month follow-up visits. Results : Twenty-eight patients in half-dose group and 27 ...
