All data in the table are the difference between the first visit and the last visit measurements. CMT: central macular thickness; SCT: subfoveal choroidal thickness; vascular diameter (temporal): the diameter of a large choroid vessel in the temporal of subfoveal choroid; vascular diameter (nasal): the diameter of a large choroid vessel in the nasal of subfoveal choroid; OD, right eye; OS, left eye; F: first visit; L: last visit; N: no.
