We established a swine PVR model that recapitulates key clinical features found in humans and, thus, can be used to study the pathophysiology of PVR, as well as new novel therapies. GFP+ RPE cells injected into the vitreous cavity formed contractile membranes on the inner retinal surface and caused localized traction retinal detachments.

The introduction of spectral domain optical coherence tomography (SD-OCT) has enhanced Vitreoretinal Interface (VRI) imaging considerably and facilitated the diagnosis, followup, prognosis determination, and management of VRI-associated pathologies. HR-OCT became a common practical tool seen in almost every ophthalmology practice. Knowledge of SD-OCT image interpretation and recognition of pathologies are required for all ophthalmologists. This paper methodically reviews the normal aging process of the VRI and discusses several commonly encountered VRI pathologies. The role of SD-OCT imaging in VRI-associated disorders such as posterior vitreous detachment, vitreomacular traction syndrome, idiopathic epiretinal membranes, lamellar holes, pseudoholes, and full thickness macular holes is portrayed. Future perspectives of new OCT technologies based on SD-OCT are discussed.
