摘　　要：目的 探讨应用23 G灌注套管发生脉络膜下灌注的原因及防治方法.方法 对23 G玻璃体切除手术中发生灌注套管脉络膜下灌注24例进行回顾性分析.结果 24例（24眼）中,发生于原有睫状体或脉络膜脱离16例（66.7％）,前段增生性玻璃体视网膜病变（PVR）3例（12.5％）,灌注连接管固定过紧2例（8.3％）,外顶压下切除周边玻璃体3例（12.5％）.结论 应用23 G灌注套管发生脉络膜下灌注与脉络膜睫状体脱离、前段PVR及手术操作不当有关.术前充分评估、术中操作精细和及时发现并重新灌注对防治此误灌至关重要.Objective To assess the causes and prevention for subchoroidal perfusion during 23-gauge pars plana vitrectomy.Methods Retrospective analysis was performed on 24 eyes complicated with subchoroidal perfusion during 23-gauge pars plana vitrectomy.Results In 24 eyes,there were 16 eyes （66.7％） with ciliary or chorodial detachment,3 eyes （12.5％） with anterior proliferative vitreous retinopathy （PVR）,2 eyes （8.3％） with overtightened perfusion connector,3 eyes （12.5％） treated with scleral depression during vitrectomy.Conclusion The subchoroidal perfusion has been related to ciliary or chorodial detachment,anterior PVR and incorrect operative procedure.Enough evaluation before operation,careful operation and prompt detection are important to avoid subchoroidal perfusion during the operation.
