Anterior Optic Nerve Head Perfusion is Dependent on Adjacent Parapapillary Choroidal perfusion.

ABSTRACT: Recent studies reported that parapapillary microvascular dropout (MvD) was significantly associated with glaucoma and glaucoma progression. To understand the clinical relevance/importance of MvD, it is essential to know the exact vascular anatomy of optic nerve head (ONH). Although it is known that parapapillary choroid and the deep ONH structure including prelaminar tissue are both supplied by branches of short posterior ciliary artery, it remains controversial whether parapapillary choroid provides a major contribution to the prelaminar tissue perfusion. This study investigated perfusion within and around the ONH using indocyanine green angiography. Thirty-three eyes from 33 patients with primary open-angle glaucoma and 10 eyes from 10 normal subjects were included. The temporal sequence
