Retinal detachment with tears can be cured by scleral buckling by synthetic material pressure retino-choroidopathy without cautery (diathermy, cryo- or photocoagulation) to tear edges on conditions: (1) To use the encircling Silastic 3-mm band (equatorial or oblique according to tear site) giving a permanent buckle. The segmental buckle may recede reopening the tear and its retino-choroidopathy effect may not be sufficient to seal the tear. (2) Not to evacuate the subretinal fluid leaving the ocular tension at end of operation a bit high [about 25 mm Hg in the first operation and 5 mm Hg (Schøtz) in the recent reoperation above the preoperative level]. The synthetic material pressure retino-choroidopathy seals the tear and lowers the ocular tension in subsequent days with beter buckling. (3) As these conditions may not be attained, it is wiser to use minimal diathermy or cryo-therapy to seal the tear.
伴有裂孔的视网膜脱离可通过巩膜扣带术治愈，即使用合成材料压迫视网膜脉络膜病变，无需对裂孔边缘进行电烙（透热疗法、冷冻或光凝），条件如下：（1）使用3毫米宽的硅橡胶环扎带（根据裂孔位置采用赤道部或斜行放置），以形成永久性扣带。节段性扣带可能会退缩，导致裂孔重新开放，其对视网膜脉络膜病变的作用可能不足以封闭裂孔。（2）不排出视网膜下液，使手术结束时眼压略高[首次手术时约为25毫米汞柱，近期再次手术时高于术前水平5毫米汞柱（许茨眼压计测量值）]。合成材料压迫视网膜脉络膜病变可封闭裂孔，并在随后几天随着更好的扣带作用降低眼压。（3）由于可能无法达到这些条件，明智的做法是使用最小程度的透热疗法或冷冻疗法来封闭裂孔。
