Okun指出,15年前认为每一例视网膜脱离手术都需要放出视网膜下液,近5年来又提出了不放液的适应症。作者本人也逐渐取得了不放液的经验,确实发现一些以前需要放液的病例行不放液手术亦获得了成功。Custodis与Lincoff等已明确证实只要将视网膜裂孔封闭,视网膜下液会自然吸收。但是视网膜脱离手术不放液适用到什么程度而不发生近期及远期的并发症,比放液本身所致的潜在损害有无更大的危险性,目前仍不能肯定。作者目前认为,只有那些情况复杂的视网膜脱离病例才需要排放视网膜下液。
Okun pointed out that 15 years ago that every case of retinal detachment surgery need to release subretinal fluid, the past 5 years and put forward the indication of no liquid. The author himself also gradually gained experience of no liquid release and indeed found that some cases that previously required liquid excretion also achieved success. Custodis and Lincoff, etc. have clearly confirmed that as long as the retinal hiatus closed, subretinal fluid will naturally absorb. However, retinal detachment surgery is not fluid to what extent without the occurrence of short-term and long-term complications, than the liquid itself caused by potential damage without greater risk, is still not sure. The authors now believe that only those cases of retinal detachment complicated cases of the need to discharge subretinal fluid.
