New techniques adapted for vitrectomy surgery, including the use of silicone oil and perfluorocarbon liquids, have been applied very successfully to giant retinal tears. Most surgeons thus turn immediately to vitrectomy for all giant tears. The authors have found that patients with giant tears usually have such rapid flow of fluid from the vitreous to the aqueous that repeated paracenteses can be performed without shallowing the anterior chamber, thus allowing injection of sufficient gas into the vitreous cavity to unroll and tamponade the giant tear without the need for vitrectomy. This makes pneumatic retinopexy a feasible alternative for those selected fresh giant tears that have mobile flaps and extend less than 180 degrees.
Five consecutive patients with giant retinal tears were treated with pneumatic retinopexy using paracentesis and two or more gas injections. They were followed at least 2 years.
Four of the five tears were successfully reattached, although a new tear developed in one, and scleral buckling surgery was performed 11 months after the pneumatic retinopexy.
The authors conclude that pneumatic retinopexy is a reasonable alternative for selected patients with giant retinal tears.
适用于玻璃体切除术的新技术,包括硅油和全氟碳液体的使用,已非常成功地应用于巨大视网膜裂孔。因此,大多数外科医生对所有巨大裂孔都立即采用玻璃体切除术。作者发现,巨大裂孔患者通常存在玻璃体至房水的液体快速流动,以至于可以反复进行前房穿刺而不会使前房变浅,从而能够向玻璃体腔注入足够的气体以展开并填塞巨大裂孔,而无需进行玻璃体切除术。这使得气体视网膜固定术成为那些选定的、具有可活动瓣且延伸小于180度的新鲜巨大裂孔的可行替代方法。
连续5例巨大视网膜裂孔患者采用前房穿刺及两次或更多次气体注射进行气体视网膜固定术治疗。对他们进行了至少2年的随访。
5个裂孔中有4个成功复位,尽管其中1个出现了新的裂孔,并在气体视网膜固定术后11个月进行了巩膜扣带手术。
作者得出结论,气体视网膜固定术是选定的巨大视网膜裂孔患者的合理替代方法。
