OCT angiographic findings of myopic CNV

Macular CNV develops in around 10% of high myopes and is the biggest cause of the central visual loss. Myopic CNV tends to be smaller and less exudative than CNV due to AMD. In natural course as well as in treated eyes, myopic CNV goes through 3 phases; active phase, scar phase, and atrophic phase (CNV-related macular atrophy).
The development of CNV-related macular atrophy is characteristic to myopic CNV. Recent analyses using swept-source OCT showed that this was not simply a chorioretinal atrophy but was a hole of Bruch’s membrane.
OCT angiography is a novel and powerful tool to visualize the detailed structure of myopic CNV. In this study, OCT angiographic features of myopic CNV in 3 different phases are shown through many cases. The relationship between myopic CNV and its origin will also be presented.
