To investigate the signal intensity obtained from the vitreoretinal interface using the spectral domain 3D OCT images.Methods
Review of spectral domain optical coherence tomography (OCT) examinations; mapping of the intensity of the tomographic signal over the posterior pole using the 3D reconstruction software; Retrospective study of the signs revealed. Chi-square was used.Results
Mapping the signal intensity over the posterior pole was named as Vitreoretinal Interface Signal Topography (V.I.SI.T.); VISIT images offer views of the epicenters and retinal folds associated with epiretinal membranes, a tool to followup the progress of the disease and to investigate the direction of the tractional forces; VISIT images allow the visualization of the borders of internal limiting membrane peeling and the inner retinal defects after an ILM rhexis; VISIT images revealed white plaques at the vitreoretinal interface, which were named as saltmarshes (SAM); SAMs are reproducible, exhibit interocular symmetry, faint in older ages and they correlate with the epicenters of ERMs.Conclusion
En face VISIT images offers unique information about the vitreoretinal interface; the saltmarshes sign may indicate the areas of strong vitreoretinal adherence and strain and/or the cortex remnants after a posterior vitreous detachment.
