视网膜前膜/黄斑皱褶 有时在黄斑区的内表面可能会出现一层半透明的细疤痕。 疤痕像一般生物层一样可能会增生和收缩，从而引起黄斑区的变形和皱缩。由于视网膜的黄斑区是光感神经层中最敏感的部分，负责精细的视力，因此患有视网膜前病变的患者可能会视力失真（直线将被视为波浪形）和视力下降。 如果不去除，疤痕层可能会继续增厚并收缩，导致视力进一步丧失。 在某些患者中，疤痕层的收缩可能会导致黄斑神经层破裂（称为黄斑裂孔）并可能导致更严重的视力丧失。早期的切除视网膜前膜手术，可以阻止视力下降并逆转或减少视觉失真。https://www.isec.my/wp-content/uploads/2019/03/img_epiretinal01.jpg
