We combined heads-up 3-dimensional (3D) 27-gauge microincision vitrectomy surgery (27GMIVS) with a very low-intensity illumination system.
This study was based on a retrospective, interventional case series of 6 eyes of 6 patients with macular disease. All patients underwent heads-up 3D 27GMIVS and the power of the intraocular illuminator was set to its minimum level, 1% (approximately 0.1 lm), throughout the surgery.
We found that the procedure was easy when the heads-up 3D system was used, but not through the eyepiece of a microscope. All surgeries were successfully finished without any complications. Postoperative visual acuity was restored or maintained in all eyes during the follow-up period.
Heads-up, 3D system-assisted 27GMIVS with minimal illumination enabled excellent intraoperative visualization of retinal tissues, caused minimal phototoxicity to the macular retinal cells, and might therefore represent the next step in the development of an ideal, minimally invasive method of treating macular disease.
我们将直视下三维（3D）27G微切口玻璃体切除术（27GMIVS）与极低强度照明系统相结合。
本研究基于一项对6例黄斑疾病患者的6只眼睛进行的回顾性干预性病例系列研究。所有患者均接受直视下3D 27GMIVS，术中眼内照明器的功率设定为最低水平，即1%（约0.1流明）。
我们发现，使用直视下3D系统时操作简便，但不是通过显微镜目镜操作。所有手术均顺利完成，无任何并发症。随访期间所有患眼的视力均得以恢复或维持。
直视下、3D系统辅助的27GMIVS联合最低限度照明能够在术中出色地观察视网膜组织，对黄斑视网膜细胞造成的光毒性极小，因此可能代表着治疗黄斑疾病的理想微创方法发展的下一步。
