    The study assessed the relationship between the posterior precortical vitreous pocket (PPVP) and retinal parameters in 65 healthy subjects.

  • 2

    PPVP was found in 72.3% of participants, with significant differences in retinal thickness and volume between PPVP-positive and negative groups.

  • 3

    The PPVP-positive group exhibited higher vessel density in both superficial and deep nasal retina compared to the PPVP-negative group.

  • 4

    Findings suggest that PPVP may influence retinal structure and blood flow, indicating its potential role in the vitreoretinal interface.

  • 5

    This research enhances understanding of PPVP's physiological significance and its implications for retinal disorders.
