Indocyanine green angiograpy test parameters were defined graphically. (A) Imax; (B) Tmax; (C) T1/2. Note. Imax indicated the magnitude of intensity from the onset of ICG to maximum intensity; Tmax indicated the time from the onset of ICG to the maximum intensity, and the T1/2 indicated the time required to reach the half-maximum intensity from the onset of ICG.
