Persistent retinal detachment following scleral buckling may be caused by persistent open retinal tears with a large amount of subretinal fluid, despite proper positioning of the buckle. In this study we evaluated the effectiveness of supplemental pneumatic retinopexy in flattening of the detached retina.
During 1990-1994 twelve cases of persistent retinal detachment following scleral buckling operation with appropriate position of the buckle, underwent supplemental gas injection.
Reattachment of the retina with complete absorption of the subretinal fluid was observed within 24-48 hours from the gas injection in all eyes. Three eyes redetached and required additional operations. At the end of the follow-up (mean 16 months) the retina was attached in all eyes, and the visual acuity was 20/120 or better in 11 eyes, and 20/30 or better in 7 eyes. No complications were observed.
Pneumatic retinopexy for persistent retinal detachment, following scleral buckling, is effective in obtaining fast flattening of the retina and achieving good visual results.
巩膜扣带术后持续性视网膜脱离可能是由于存在持续性开放视网膜裂孔并有大量视网膜下液，尽管扣带位置正确。在本研究中，我们评估了补充性气体视网膜固定术在使脱离视网膜变平方面的有效性。
在1990年至1994年期间，12例巩膜扣带术后出现持续性视网膜脱离且扣带位置合适的患者接受了补充性气体注射。
所有患眼在气体注射后24至48小时内均观察到视网膜复位且视网膜下液完全吸收。3只眼再次脱离，需要再次手术。随访结束时（平均16个月），所有患眼视网膜均已复位，11只眼视力达到20/120或更好，7只眼视力达到20/30或更好。未观察到并发症。
对于巩膜扣带术后的持续性视网膜脱离，气体视网膜固定术可有效快速使视网膜变平并取得良好的视觉效果。
