During conventional application of vital dyes not only the macular area but also the peripheral retina and the RPE within the macular hole is exposed by the dye.


To achieve a selective staining preretinal structures, we developed a novel applicator. The so-called "Vitreoretinal- internal limiting membrane color enhancer (VINCE)" has an outer diameter of 20-gauge containing a flexible tip on a metal cannular. The VINCE can be filled with vital dyes.


The VINCE performed well in a series of enucleated pig eyes. After the a complete vitreous removal the VINCE was gently inserted through a standard sclerostomy into the air filled vitreous cavity. The adjustable tip was inflated and gently exposed to the retinal surface with a circular movement, allowing the dye to paint in minimal area of essential interest. The created stream was limited to the planned edge of the ILM-rhexis strictly preventing any dye at the center of the macula. Dye was not unintendedly lost at the site of the sclerotomy or additional retinal structures.


The VINCE allows a selective painting of preretinal structures with surgical interest, limiting possible side effects of currently used vital dyes.
