目的探讨脉络膜缺损区内裂孔的临床特点及手术方法，以提高手术疗效。方法对１０例（１１眼）脉络膜缺损区内裂孔患者施行玻璃体视网膜手术，术中在高倍显微镜下观察视网膜裂孔的形态及与缺损边缘的关系，并行相应处理，气体或硅油填充。结果术后１０例１１眼视网膜解剖复位１０眼，视力均有不同程度提高。结论脉络膜缺损区内裂孔的牵引与缺损区边缘关系密切，裂孔多为圆形或椭圆形，缺损区处巩膜凹陷。充分的玻璃体切割，恢复视网膜弹性，封闭裂孔及缺损区边缘是手术成功的关键，惰性气体及硅油填充更提高了视网膜复位的安全可靠性。
Objective To investigate the clinical characteristics and operative methods of the intra-choroidal fissure in order to improve the curative effect. Methods Vitreoretinal surgery was performed in 10 patients (11 eyes) with intraocular cavities in the choroidal defect area. The morphology of the retinal breaks and the relationship with the defect margin were observed under high magnification microscope with the corresponding treatment, gas or silicone oil filling. Results 10 cases of postoperative 10 cases of retinal anatomy reduction in 10 eyes, visual acuity improved in varying degrees. Conclusion The traction of the hiatus in the choroidal defect area is closely related to the margin of the defect area. Most of the fissures are round or oval, and the scleral recess is in the defect area. Full vitrectomy, restoration of retinal elasticity, closure of the hole and the edge of the defect area is the key to successful operation. The filling of inert gas and silicone oil improves the safety and reliability of retinal reattachment.
