目的　评价甲基强的松龙冲击疗法（简称冲击疗法）在脉络膜脱离型机网膜脱离（简称脉脱型网脱）术前应用的疗效。方法　治疗组１０例（１０眼）在本病术前采用冲击疗法，对照组１０例（１０眼）在本病术前采用一般疗法。比较二者术后的疗效。结果　　　手术复位率：治疗组 ７０％．对照组 ４０％，二者有显著性差异（Ｐ＜０． ０５）。结论术前采用冲击疗法治疗本病，能更迅速、更可靠地抑制脉络膜炎症．更快地使脉脱减轻或消失．更有效地抑制ＰＶＲ形成，从而早期手术，明显提高手术复位率，进一步提高视力，无副作用。 Objective To evaluate the efficacy of methylprednisolone impact therapy (referred to as impact therapy) in the preoperative application of choroidal detachment type retinal detachment (referred to as pulse stripping reticulation). Methods Ten patients (10 eyes) in the treatment group were treated with shock therapy before the operation, while 10 patients (10 eyes) in the control group were treated with general therapy before the operation. Compare the efficacy of the two after surgery. Results The rate of operation reduction was 70% in the treatment group. The control group 40%, the two were significantly different (P <0. 05). Conclusion Preoperative impact therapy for the treatment of this disease can more quickly and reliably inhibit choroidal inflammation. Reduce or eliminate the pulse more quickly. More effectively inhibit the formation of PVR, which early surgery, significantly improve the rate of surgical reduction, to further improve vision, no side effects.
