  1. OCT = Optical coherence tomography; VKH = Vogt-Koyanagi-Harada; CSCR = central serous chorioretinopathy; BCVA = best corrected visual acuity; LogMAR = logarithm of the minimum angle of resolution; PED = pigment epithelium detachment; RPE = retinal pigment epithelium; ILM = internal limiting membrane.
  2. aBCVA and thickness was denoted as mean ± standard deviation.
