This study aimed to investigate changes in choroidal thickness after pars plana vitrectomy (PPV) with and without air tamponade in patients with idiopathic epiretinal membrane (ERM). We retrospectively reviewed 61 patients with ERM who underwent a 25-gauge transconjunctival sutureless PPV. The patients were divided into two groups: the air tamponade group (30 eyes) and the nontamponade group (31 eyes). Subfoveal choroidal thickness (SFCT) was analyzed over 12 months. No significant differences were seen between the two groups at baseline. For all patients, the SFCT was significantly thicker at 1 month after surgery and significantly thinner at 6 and 12 months after surgery than preoperative values. In the subgroup analysis, there was no significant difference in SFCT 3 months after surgery compared with the preoperative values in both groups, but SFCT was significantly lower 6 months after surgery in both groups. In conclusion, our results showed that choroidal thickness temporarily increased after surgery and then gradually decreased until 12 months after the PPV for ERM.
本研究旨在调查特发性视网膜前膜（ERM）患者在进行或不进行空气填塞的玻璃体切割术（PPV）后脉络膜厚度的变化。我们回顾性分析了61例行25G经结膜无缝合PPV的ERM患者。患者被分为两组：空气填塞组（30只眼）和非填塞组（31只眼）。对黄斑中心凹下脉络膜厚度（SFCT）进行了为期12个月的分析。两组在基线时无显著差异。对于所有患者，术后1个月时SFCT显著增厚，术后6个月和12个月时显著变薄，均低于术前值。在亚组分析中，两组术后3个月时SFCT与术前值相比无显著差异，但两组术后6个月时SFCT均显著降低。总之，我们的结果表明，ERM患者PPV术后脉络膜厚度暂时增加，然后逐渐下降，直至术后12个月。
