The release of subretinal fluid is only required in certain complicated types of retinal detachment and should be avoided when possible. An important consideration in releasing subretinal fluid is the timing of this step in relation to the application of diathermy or cryotherapy as the primary treatment modality. Drainage should precede application of cryotherapy but follow the use of diathermy. The most satisfactory site for drainage is either immediately above or below the medial or lateral long ciliary nerve, just posterior to the equator of the globe. A technique for drainage of subretinal fluid has been developed and evaluated. An 'L'-shaped scleral flap is dissected to produce a relatively staphylomatous zone and the choroid is perforated near its center.
仅在某些复杂类型的视网膜脱离中才需要放出视网膜下液，并且应尽可能避免。放出视网膜下液时的一个重要考虑因素是该步骤相对于作为主要治疗方式的透热疗法或冷冻疗法应用的时机。引流应在冷冻疗法应用之前进行，但要在透热疗法之后。最理想的引流部位是在眼球赤道后方，内侧或外侧睫状长神经上方或下方紧邻处。已经开发并评估了一种视网膜下液引流技术。切开一个“L”形巩膜瓣以形成一个相对的葡萄肿区域，并在脉络膜中心附近穿孔。
