A specially designed cannulated extrusion needle facilitates the internal drainage of subretinal fluid during vitreoretinal microsurgery. Case histories demonstrate the use of this instrument in the management of complex retinal detachments including eyes with preretinal and subretinal hemorrhage, proliferative vitreoretinopathy with open peripheral retinal breaks, retinal detachment with giant retinal tear, and combined traction-rhegmatogenous detachments due to diabetic retinopathy. This method of internal drainage appears to have specific advantages over standard techniques by allowing the removal of subretinal hemorrhage, the utilization of pre-existing peripheral breaks for internal drainage, and the complete reattachment of shallow posterior pole retinal detachments to allow laser endophotocoagulation.
一种专门设计的带套管的挤压针便于在玻璃体视网膜显微手术中进行视网膜下液的内引流。病例记录显示了该器械在复杂视网膜脱离治疗中的应用，包括伴有视网膜前和视网膜下出血的眼睛、伴有周边视网膜开放性裂孔的增殖性玻璃体视网膜病变、伴有巨大视网膜裂孔的视网膜脱离以及糖尿病性视网膜病变所致的牵引性-孔源性联合视网膜脱离。这种内引流方法似乎比标准技术具有特定优势，它能够清除视网膜下出血，利用现有的周边裂孔进行内引流，并使后极部浅脱离的视网膜完全复位以便进行激光眼内光凝。
