En Face Imaging of Posterior Precortical Vitreous Pockets Using Swept-Source Optical Coherence Tomography
PURPOSE. To obtain sequential flat (en face) images of posterior precortical vitreous pockets (PPVPs) using swept-source optical coherence tomography (SS-OCT). METHODS. We performed SS-OCT in the right eyes of 112 volunteers (mean age, 30.1 years; mean refraction, 2.5 diopters) while sitting using 12-mm horizontal, vertical scans of the 12- 3 9-mm plane 3 2.6-mm depth through the macula and optic disc. En face images of the posterior vitreous were obtained by En-View, a SS-OCT program. RESULTS. Swept-source OCT visualized the PPVPs and Cloquet’s canals in all subjects; the PPVPs appeared as boat-shaped lacunae in the horizontal ...
