Monochromatic endoillumination for epimacular membrane surgery

We attempted to simultaneously increase visualization of epimacular membranes and minimize retinal phototoxicity by filtering the light of the endoilluminator during vitreous surgery. The monochromatic filters we employed to eliminate short wavelengths were not useful because they reduced the level of illumination. We advise using the lowest level of illumination possible and an ultraviolet/infrared filter over the light source when working close to the retinal surface. The filter can be adapted to replace the fluorescein filter in the Ocutome console to facilitate insertion and withdrawal.
