|Title||New insight in peripapillary intrachoroidal cavitation|
|Purpose||To specify the pathophysiological features of the peripapillary intrachoroidal cavitation (ICC), one of the still poorly understood complications of high myopia.|
|Methods||The combined use of fundus images and optical coherence tomography (OCT) sections forms the basis for in-depth analysis of a case of ICC. For longitudinal evolution, the information is obtained by comparing the OCT images of the same location over 6 years. The OCT serial sections acquired during the same session highlight the various aspects of this condition depending on the location of the section.
Thanks to the different clinical signs collected by combining and crossing the longitudinal and transversal informations, the characteristics of the ICC are thus identified.
|Results||A cleft in the parapapillary gamma zone serves as a point of passage for the vitreous fluid. This liquid, over time, seeps into the choroid and progresses, causing choroidal changes typical of this condition. The clinical signs of ICC reflect both the passive and reactional changes induced by fluid progression. The iconography illustrating these different aspects is presented.|
|Conclusion||The combination of longitudinal evolution parameters and OCT serial sections data has allowed for a better understanding of ICC’s previously unrecognized points. We confirm that the different clinical manifestations of this entity constitute a continium.|
