Diamond dust particles were identified within patients' eyes both during vitrectomy procedures using diamond-dusted membrane scrapers and in postoperative clinical examinations. The particles had no impact on the patients' vision and caused no apparent sequelae. Scanning electron microscopy analysis showed the average particle size to be 23.4 μm and an unequal surface area for particle adhesion onto the soft tip. It was determined that diamond dust particles can dislodge from the silicone tip of the Tano diamond-dusted membrane scrapers during the insertion into valve trocars throughout vitrectomy operations and deposit on the retinal surface or within macular holes. Ophthalmologists should be aware of residual diamond particles during procedures and consider diamond dust retinopathy in the differential diagnosis of crystalline retinopathies. Understanding the appearance of residual particles on the retina allows for future studies revealing the long-term impact on patient's visual performance.
在使用涂有钻石粉的膜刮匙进行玻璃体切割手术期间以及术后临床检查中，均在患者眼内发现了钻石粉尘颗粒。这些颗粒对患者视力没有影响，也未造成明显后遗症。扫描电子显微镜分析显示，颗粒平均粒径为23.4μm，且颗粒附着在软尖端上的表面积不均等。已确定在整个玻璃体切割手术过程中，将涂有钻石粉的Tano膜刮匙插入阀门套管针时，钻石粉尘颗粒会从硅树脂尖端脱落，并沉积在视网膜表面或黄斑裂孔内。眼科医生在手术过程中应注意残留的钻石颗粒，并在结晶性视网膜病变的鉴别诊断中考虑钻石粉尘视网膜病变。了解视网膜上残留颗粒的外观有助于未来研究揭示其对患者视觉功能的长期影响。
