- Findings on image overlay corresponded with the objective measurements. Conclusions: Noninvasive digital red-free photography is an informative tool for the objective measurement of the vessel displacement during ERM formation. Contraction and release of the ERM were noted. MeSH terms Aged Epiretinal Membrane / complications* Female

- Red Free optomap Red Free Unlike white light used in conventional products, this technology incorporates low powered laserwavelengths that scan simultaneously. This allows review of the retinal substructures in their individual laser separations. The red free view scans from the sensory retina to the pigment epithelial layers.

- The sequential stereo technique can be combined with monochromatic photography to add additional diagnostic information. Monochromatic techniques and filter choices are based on the premise that the human fundus is mostly red in appearance, hence the use of "red free" light to darken the deep layers of the retina and choroid.

- Red free fundus photography It is a technique of monochromatic retinal imaging which uses green contrast filters to modify individual tones in monochrome images and the increased scattering of light at shorter wavelengths. Various fundus structures can be better visualized by limiting the spectral range of the illuminating source.3
