Abstract

PURPOSE

This study evaluated 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.s.

METHODS

This is a prospective comparative observational study. Consecutive patients that underwent 25G vitrectomy and ILM peeling using a standard operating microscope (SOM) (25 eyes), DAVS Ver. 1.1 (12 eyes), or DAVS Ver. 1.3 (13 eyes) were enrolled. The SOM and DAVS Ver. 1.1 groups used 0.075% ICG, and the DAVS Ver. 1.3 group used 0.025% ICG. In DAVS Ver. 1.1, macular CCR was compared between four different presets in the red, green, and blue channels: Default (Red (R) 100%, Green (G) 100%, and Blue (B) 100%); Preset 1 (R 20%, G 100%, B 100%); Preset 2 (R 80%, G 80%, B 100%), and Preset 3 (R 85%, G 100%, B 90%). In DAVS Ver. 1.3, macular CCR was evaluated using two different customized settings that modified the hue and saturation: Customized Setting 1 (R 86, G 100, B 100%, Hue +2°, Saturation 90%, Gamma 1.2) and Customized Setting 2 (R 90, G 100, B 100%, Hue +20°, Saturation 100%, Gamma 0.9). All patients underwent ophthalmologic examinations including BCVA at baseline and at 12 months.

RESULTS

In DAVS Ver. 1.1, macular CCR was highest in Preset 3 ( < 0.01). The CCR of Customized Setting 2 of DAVS Ver. 1.3 using 0.025% ICG did not differ from that of Preset 3 in DAVS Ver. 1.1 using 0.075% ICG. Furthermore, there was no significant difference in BCVA between the Customized Setting 2 of DAVS Ver. 1.3 with 0.025% ICG and the Preset 3 of DAVS Ver. 1.1 with 0.075% ICG groups at baseline and at 12 months ( > 0.05, respectively).

CONCLUSION

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

摘要

目的

本研究使用不同吲哚菁绿（ICG）浓度的数字辅助玻璃体视网膜手术（DAVS）的不同颜色设置，评估内界膜（ILM）的颜色对比度（CCR）。

方法

这是一项前瞻性比较观察性研究。纳入连续接受25G玻璃体切除术并使用标准手术显微镜（SOM）（25只眼）、DAVS Ver. 1.1（12只眼）或DAVS Ver. 1.3（13只眼）进行ILM剥除的患者。SOM组和DAVS Ver. 1.1组使用0.075%的ICG，DAVS Ver. 1.3组使用0.025%的ICG。在DAVS Ver. 1.1中，比较红色、绿色和蓝色通道中四个不同预设下的黄斑CCR：默认（红色（R）100%，绿色（G）100%，蓝色（B）100%）；预设1（R 20%，G 100%，B 100%）；预设2（R 80%，G 80%，B 100%）和预设3（R 85%，G 100%，B 90%）。在DAVS Ver. 1.3中，使用两种修改色调和饱和度的不同定制设置评估黄斑CCR：定制设置1（R 86，G 100，B 100%，色调 +2°，饱和度90%，伽马值1.2）和定制设置2（R 90，G 100，B 100%，色调 +20°，饱和度100%，伽马值0.9）。所有患者在基线和12个月时均接受包括最佳矫正视力（BCVA）在内的眼科检查。

结果

在DAVS Ver. 1.1中，预设3的黄斑CCR最高（<0.01）。使用0.025% ICG的DAVS Ver. 1.3的定制设置2的CCR与使用0.075% ICG的DAVS Ver. 1.1的预设3的CCR无差异。此外，在基线和12个月时，使用0.025% ICG的DAVS Ver. 1.3的定制设置2组与使用0.075% ICG的DAVS Ver. 1.1的预设3组之间的BCVA无显著差异（分别>0.05）。
