From: Multi-modality imaging findings of huge intrachoroidal cavitation and myopic peripapillary sinkhole
Identification of peripapillary intrachoroidal cavitation and sinkhole on multi-modality images. a Multi-color images of peripapillary intrachoroidal cavitation and tilted ONH show a well-circumscribed, caesious, peripapillary lesion coalesced with the ONH (red dots) and its inferotemporal sinkhole (blue dots) in the myopic conus. The inferotemporal retinal vein covers the sinkhole of the peripapillary intrachoroidal cavitation in the myopic conus. b Infrared reflectance demonstrating a peripapillary dark reflective region (red arrows), corresponding to the red dots in (a, c). A clear border of the sinkhole (blue arrows) could be observed in green reflectance, corresponding to the blue dots in (a, d). The sinkhole (size: 0.34 mm2) on an en face image (blue arrow). e The intrachoroidal cavity (size: 7.85 mm2) on an en face image (red arrow). f EDI-OCT (green dashed circle in a) showing the entire profile of the peripapillary intrachoroidal cavitation (yellow arrows). g A thinner retinal nerve fiber was detected above the peripapillary intrachoroidal cavitation region (red circle), in accordance with the EDI-OCT image in (f, h). The coalescence of peripapillary intrachoroidal cavitation (red arrow) and ONH (green arrow) as evident on an ocular B scan ultrasound image, as well as the sinkhole (blue arrow), consistent with (a). i Visual field testing shows that the dark defects (red arrow) connected with the blind spot, consistent with the peripapillary intrachoroidal cavitation location in (a) and (h).
