Abstract
BackgroundPeripapillary intrachoroidal cavitation was described as the presence of an asymptomatic, well-circumscribed, yellow-orange, peripapillary lesion at the inferior border of the myopic conus in eyes with high myopia.Case presentationA 66-year-old myopic Chinese man was enrolled and his multi-color imaging examination showed a well-circumscribed, caesious, peripapillary lesion coalesced with the optic nerve head vertically rotated and obliquely tilted, together with an inferotemporal sinkhole in the myopic conus. The optical coherence tomography images showed an intrachoroidal hyporeflective space, schisis, an intracavitary septum located below the retinal pigment epithelium and inserted beneath the optic nerve head, as well as a sinkhole between the peripapillary intrachoroidal cavitation and the vitreous space.ConclusionsBoth myopic colobomas and sinkhole in myopic conus may contribute the coalescence of intrachoroidal cavitation with optic nerve head. These qualitative and quantitative new findings will be beneficial for understanding its pathomorphological mechanism, and the impact on optic nerve tissue of myopic patients.
Highlights
Peripapillary intrachoroidal cavitation was described as the presence of an asymptomatic, wellcircumscribed, yellow-orange, peripapillary lesion at the inferior border of the myopic conus in eyes with high myopia.Case presentation: A 66-year-old myopic Chinese man was enrolled and his multi-color imaging examination showed a well-circumscribed, caesious, peripapillary lesion coalesced with the optic nerve head vertically rotated and obliquely tilted, together with an inferotemporal sinkhole in the myopic conus
Peripapillary intrachoroidal cavitation was first described by Freund et al [1] using optical coherence tomography (OCT)
A 66-year-old myopic Chinese man was referred to our clinic and multi-color imaging showed a wellcircumscribed, caesious, peripapillary lesion coalesced with the optic nerve head (ONH) vertically rotated and obliquely tilted, together with an inferotemporal sinkhole in the myopic conus (Fig. 1)
Summary
Both myopic colobomas and sinkhole in myopic conus may contribute the coalescence of intrachoroidal cavitation with optic nerve head.
