Risk Factors for Residual Vitreous Cortex at the Fovea after Posterior Vitreous Detachment during Vitrectomy in Ocular Trauma

Figure 1

Formation of surgical posterior vitreous detachment (PVD). (a) The attraction of the vitreous cortex with high vacuum levels transmitted through the vitrectomy probe, over the optic nerve. (b) The vitreous cortex is gently pulled up by the vitrectomy probe. (c) Suspension of triamcinolone acetonide granules in the vitreous cavity. (d) Successful surgical PVD is confirmed by the appearance of a peripapillary Weiss ring.
