Purpose To direct attention to the structures of the posterior hyaloid as visualized by SD OCT, and to improve understanding of vitreo‐retinal biomechanics. Methods Findings were collected from a Wetzlar study cohort of subjects who gave their informed consent to gather experience in vitreal SD OCT. In addition, OCT images were worked up retrospectively from the Mannheim pool of recordings. Exams were performed by the RS 3000 SD OCT (Nidek) or by the Spectralis SD OCT (Heidelberg engineering). Images underwent a modified processing to favour the visualization of vitreous structures. Results Observations range from a completely attached and homogeneous hyaloid with regular foveal profile at the age of 75, to premacular vitreal bursae and intravitreal lacunae, regions of low and high density within an apparently disintegrating hyaloid, intravitreal condensates and supposed cell aggregations. Various patterns of holes within the posterior limitating vitreal membrane appeared in connection with vitreo‐retinal and vitreo‐papillar traction of a partially detached vitreous Conclusion OCT visualization of vitreous structures contributes to our understanding of vitreal degradation and vitreo ‐ retinal interaction.Commercial interest
