目的探讨儿童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12例(14眼)脉络膜缺损合并视网膜脱离的儿童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12例(14眼)一次手术视网膜解剖复位12眼,占85.7%;所有患儿视力均有不同程度提高。结论儿童脉络膜缺损区内裂孔多为圆形或椭圆形,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,硅油填充提高了视网膜复位的安全性及可靠性。
Objective To investigate the clinical characteristics and surgical methods of the hiatus in children with choroid defect in order to improve the curative effect. Methods Vitreoretinal surgery was performed in 12 children (14 eyes) with choroidal defect and retinal detachment. The morphology of the retinal breaks and the relationship with the margin of the defect were observed under high magnification microscope with the corresponding treatment, gas or silicone oil filling. Results 12 cases (14 eyes) underwent anatomic reattachment in 12 eyes, accounting for 85.7%. Visual acuity was improved in all cases. Conclusion The majority of hiatus in children with choroidal defects are round or oval. The adequate vitrectomy, restoration of retinal elasticity, closure of the hole and the margin of the defect are the keys to successful operation. Silicone oil filling improves the safety and reliability of retinal reattachment.
