Whorl-Like Collagen Fiber Arrangement Around Emissary Canals in the Posterior Sclera.

ABSTRACT:

Purpose

To investigate the collagen fiber arrangement around emissary canals in the posterior sclera.

Methods

One hundred sixty-five eyes of 93 patients who underwent polarization-sensitive optical coherence tomography (PS-OCT) examinations in 2019 in the Institute of Science Tokyo were studied. Multimodal imaging, including streamline images derived from PS-OCT data, B-scan images, and indocyanine green angiography (ICGA) images, was used to investigate the collagen fiber arrangement around emissary canals and scleral pits in vivo. Additionally, the collagen fiber arrangement around the emissary canals in porcine sclera was examined using scanning electron microscopy and light microscopy.

Results

Streamline images showed whorl-like collagen fiber arrangements on all
