Purpose: To evaluate posterior vitreous structures using swept-source (SS) optical coherence tomography (OCT)
with en face imaging.
Methods: We retrospectively reviewed OCT images of healthy individuals who did not have intra-ocular disease.
We obtained high-definition horizontal and vertical line scans crossing the fovea and 3D scans using SS-OCT,
with the 3D scan centered between the fovea and the optic-nerve head. An enhanced vitreous visualization
function was used to highlight vitreous structures. En face mode was used to measure the area of Martegiani (AM)
and bursa premacularis (BP). We performed all measurements using a built-in function of the viewing software.
Results: We enrolled 24 eyes from 12 healthy individuals. The mean patient age was 28.7 ± 4.6 years (range, 24
to 39 years). The mean AM and BP areas were 5.73 ± 0.88 and 18.76 ± 6.95 mm2, respectively. In en face imaging,
AM shape was most frequently a vertical oval (18 / 22, 81.8%), while the predominant BP shape was round
(16 / 20, 80.0%). AM was in contact with the optic disc, either at the temporal-disc margin (13 eyes, 59.1%) or the
nasal optic-disc margin (9 eyes, 40.9%).
Conclusions: Posterior vitreous structures, such as AM and BP, were readily visualized using en face imaging
with SS-OCT. Investigating normal vitreous configuration might help in understanding changes in vitreous structures
associated with retinal pathology.
