探讨一种新技术在硅油眼内填充物取出后视网膜再脱离中识别隐匿性视网膜裂孔的有效性。该技术包括视网膜下染料的注射和通过不明破裂处的挤压。一项前瞻性干预性病例系列研究。主要的观察指标为破裂检出率、眼内填充物取出后3个月视网膜复位率和术后视力改善。共有21例患者符合研究标准。除2例（成功率90.4%）外，其余均能成功识别隐匿性血管瘤。在大多数情况下，在激光视网膜固定术疤痕的后缘发现了裂孔。硅油取出后12周，所有病例均可见视网膜完全附着。平均视力从术前的logMAR 1.4改善至术后的logMAR 0.81（p = 0.001）。视网膜下染料注射可用于检测视网膜再脱离患者的隐匿性视网膜裂孔，并有助于防止手术失败。
To investigate the effectiveness of a new technique for the identification of occult retinal breaks in retinal redetachment after removal of silicone oil endotamponade. The technique involves injection of subretinal dye and extrusion through the unidentified breaks. A prospective interventional case series. Main outcome measures were rate of break detection, rate of retinal attachment at 3 months after removal of endotamponade, and improvement in visual acuity after surgery. A total of 21 patients fulfilled the study criterion. The occult rhegma could be identified successfully in all except two cases (90.4 % success). In most cases the rhegma was identified at the posterior edge of the laser retinopexy scar. Complete retinal attachment could be seen in all cases at 12 weeks after removal of silicone oil. The mean visual acuity improved from logMAR 1.4, preoperatively to logMAR 0.81 (p = 0.001) postoperatively. Subretinal dye injection was useful in detecting occult retinal breaks in patients with retinal redetachment and was helpful in preventing surgical failure.
