Three eyes with preretinal macular fibrosis (PMF) were treated with the Q-switched Nd-YAG laser. The PMF was idiopathic in two eyes and associated with a vitreous hemorrhage, due to ocular trauma, in the third eye. The three eyes had in common a partial posterior vitreous detachment with vitreous traction on the macula. The Nd-YAG laser beam was focused on the detached posterior hyaloid in front of the macular region. Some holes were made in this membrane or in the adjacent collapsed vitreous cortex. Treatment increased the visual acuity in the three eyes; the vitreous remained partially detached in the two eyes with idiopathic PMF and detached completely in the eye with the secondary PMF. The disentanglement of the fovelar area was revealed by the unfolded appearance of the retinal vessels on fluoangiography.
对三只患有视网膜前黄斑纤维化（PMF）的眼睛进行了调Q Nd:YAG激光治疗。其中两只眼睛的PMF为特发性，第三只眼睛的PMF与眼外伤导致的玻璃体积血有关。这三只眼睛的共同特点是存在部分玻璃体后脱离，伴有黄斑部玻璃体牵拉。Nd:YAG激光束聚焦于黄斑区前方分离的后玻璃体膜。在该膜或相邻塌陷的玻璃体皮质上制造了一些小孔。治疗后三只眼睛的视力均有所提高；两只特发性PMF的眼睛玻璃体仍部分脱离，继发性PMF的眼睛玻璃体完全脱离。荧光血管造影显示视网膜血管展开，提示黄斑区松解。
