Traction on the posterior edge of a large tear may be an irreparable consequence of an intraocular gas tamponade used in the first instance to treat the tear. In two of three patients treated with octofluorocyclobutane (C4F8) and perfluoromethane (CF4), redetachment of a retinal tear occurred as a result of traction on the posterior edge of the tear when, prior to the operation, the posterior edge seemed to be free of any traction. With redetachment, a membrane became visible between the anterior and posterior lips of the tear. The membrane was probably posterior hyaloid augmented by cellular proliferation. The gas bubble, which had been intended to press the retina against the pigment epithelium, probably brought the detached posterior hyaloid into contact with the retina as well, and an adhesion between the hyaloid and retina formed.
对大裂孔后缘的牵拉可能是最初用于治疗裂孔的眼内气体填塞不可修复的后果。在接受八氟环丁烷（C4F8）和全氟甲烷（CF4）治疗的三名患者中的两名中，当术前裂孔后缘似乎没有任何牵拉时，由于对裂孔后缘的牵拉，视网膜裂孔再次脱离。随着再次脱离，在裂孔的前后唇之间可见一层膜。该膜可能是由细胞增殖增厚的后玻璃体膜。原本旨在将视网膜压向色素上皮的气泡，可能也使脱离的后玻璃体膜与视网膜接触，并在玻璃体膜和视网膜之间形成了粘连。
