Analysis of the subfoveal total choroidal thickness and the thickness of the individual choroidal vascular layers. a Graph showing reduction in the subfoveal total choroidal thickness (SFCT), subfoveal large choroidal vessel layer (LVL) thickness and subfoveal medium choroidal vessel/choriocapillaris layer (SVL) thickness during follow-up. The numbers represent the mean thickness values. b SD-OCT images from patient 1 showing a reduction in the subfoveal total choroidal thickness over a 33-month period.
