Seven patients with macular hole retinal detachment were treated by intravitreal gas injection with or without release of subretinal fluid. Macular buckling, diathermy, cryopexy, or vitrectomy were not used. The patients were placed prone for eight hours a day until the gas had absorbed. In five of the seven patients the retina became reattached within three days and remained reattached with follow-up periods of three to 22 months (average nine months). It is believed that such detachments are due to vitreoretinal traction and the intravitreal gas bubble relieves this traction. This technique is simple, safe, and does not require costly or sophisticated instruments. It has an added advantage in preserving macular function.
7例黄斑裂孔性视网膜脱离患者接受了玻璃体腔内注气治疗，部分患者同时联合视网膜下液引流。未采用黄斑扣带术、透热疗法、冷冻疗法或玻璃体切除术。患者每天俯卧8小时，直至气体吸收。7例患者中有5例视网膜在3天内复位，并在3至22个月（平均9个月）的随访期内保持复位状态。据信，此类视网膜脱离是由玻璃体视网膜牵拉引起的，而玻璃体内的气泡可缓解这种牵拉。该技术操作简单、安全，无需昂贵或复杂的仪器。它在保留黄斑功能方面还有额外的优势。
