Detection of Zinn-Haller Arterial Ring in Highly Myopic Eyes by Simultaneous Indocyanine Green Angiography and Optical Coherence Tomography

The HRA-OCT images confirmed that the vascular structure surrounding the optic disc observed by ICG angiography had topographic features specific to the Zinn-Haller arterial ring by OCT. The in situ observation of the circle of Zinn-Haller by simultaneous ICG angiography and OCT is a useful method to examine the Zinn-Haller ring in eyes with pathologic myopia.
