NIR imaging. a Prominent hyperreflective crystalline deposits without sclerotic choroid vessels. b The color fundus and NIR images of the same patient after 5 years showing decreased crystalline deposits. There are still no sclerotic vessels on her NIR image. c Prominent sclerotic vessels have appeared. There are much fewer crystalline deposits. Some deposits are shown in the white dotted square (yellow arrows). d NIR image of advanced-stage BCD showing prominent sclerotic choroidal vessels and no crystalline deposits
