Abstract

Purpose : To evaluate the color contrast ratio (CCR) of the internal limiting membrane (ILM) using different color settings of digitally assisted vitreoretinal surgery (DAVS) with different indocyanine green (ICG) concentrations.

Methods : Consecutive patients were enrolled that underwent 25G vitrectomy and ILM peeling using a standard operating microscope (SOM) (25 eyes), DAVS Ver. 1.1 (12 eyes), and DAVS Ver. 1.3 (13 eyes). The SOM and DAVS Ver. 1.1 groups used 0.075% ICG, and DAVS Ver. 1.3 used 0.025% ICG. In DAVS Ver. 1.1, macular CCR was compared between four different presets in the red, green, and blue channels. In DAVS Ver.1.3, macular CCR was evaluated using two different customized settings mainly modifying the hue and saturation. ILM peeling time was compared.

Results : In DAVS Ver. 1.1, macular CCR was the highest in Preset 3 (P < 0.01). The CCR of customized Setting 2 of DAVS Ver. 1.3 with 0.025% ICG did not differ from that of Preset 3 of DAVS Ver. 1.1 with 0.075% ICG. ILM peeling time did not differ between the SOM with 0.075% ICG and DAVS Ver. 1.3 groups with 0.025% ICG.

Conclusions : Customized DAVS settings enable surgeons to use a 3-fold lower ICG concentration in ILM peeling.
