Objective

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.

Methods

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.

Results

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.

Conclusions

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