Abstract

PURPOSE:

To demonstrate the presence of prevascular vitreous fissures (PVF) and posterior vitreous cisterns in vivo and correlate with the degree of vitreous degeneration (VD).

METHODS:

This was a cross-sectional study using Topcon Deep Range Imaging OCT-1 Atlantis 3D swept source optical coherence tomography for acquiring scans of posterior vitreous covering an 18 × 18-mm area in 104 eyes of 52 healthy volunteers without posterior vitreous detachment.

RESULTS:

We observed that increasing age was associated with higher VD grades (P < 0.05). Prevascular vitreous fissures, characterized by areas of lower optical density overlying the retinal blood vessels, were identified in 93 (89%) eyes, and the presence of PVF correlated with lower VD grades (P < 0.05). Presence of cisterns correlated with higher VD grades (P < 0.05). All eyes with absence of PVF were found to have established cisterns. Prevascular vitreous fissures were connected with cisterns in 44 of the 71 (62%) eyes with cisterns, while the base of the cistern was directly above retinal blood vessels in 38 (54%) eyes, which suggests that the cisterns could be derived from PVF.

CONCLUSION:

Swept source optical coherence tomography imaging can identify PVF and cisterns occurring in the context of age-related VD, and PVF appeared to be possible precursors of cisterns.
