■探讨单纯性孔源性视网膜脱离(RRD)患者术后发生变形的发生率及影响因素。
■通过在PubMed中搜索确定了变形目的相关研究,Embase,和科克伦直到2022年8月。采用ReviewManager5.4统计软件对孔源性视网膜脱离术后变形发生率进行Meta分析。
■共有12项研究报告了1133名参与者和469名患者的术后变形。荟萃分析显示,与黄斑上RRD相比,黄斑脱落病例的变形发生率更高(RR=2.88,95%CI:2.35至3.52)。在平坦部玻璃体切除术(PPV)中使用全氟化碳液体(PFCL)可降低变形视的发生率(RR=0.61,95%CI:0.41至0.92)。没有证据表明PPV组和巩膜扣带术(SB)组的参与者之间在变形方面存在任何重要差异(RR=1.04,95%CI:0.82至1.33)。在PPV组中,气体和硅油(SO)之间的变质差异很小或没有差异(RR=0.89,95%CI:0.69至1.13)。
■黄斑脱离型RRD术后变形的发生率较高,和PFCL应该是预防黄斑变性RRD病例术后变形的首选选择。
UNASSIGNED: To investigate the incidence and factors influencing the occurrence of
metamorphopsia in patients with simple rhegmatogenous retinal detachment (RRD) after surgery.
UNASSIGNED: Relevant studies of
metamorphopsia were identified by searching in PubMed, Embase, and Cochrane until August 2022. Meta-analysis of the incidence of
metamorphopsia after rhegmatogenous retinal detachment surgery was performed using
Review Manager 5.4 statistical software.
UNASSIGNED: A total of 12 studies reported 1133 participants with 469 patients with postoperative metamorphopsia. The meta-analysis showed a higher incidence of metamorphopsia in macular-off cases compared with macular-on RRD (RR = 2.88, 95% CI: 2.35 to 3.52). The use of perfluorocarbon liquid (PFCL) during pars plana vitrectomy (PPV) reduced the incidence of metamorphopsia (RR = 0.61, 95% CI: 0.41 to 0.92). There was no evidence of any important difference in metamorphopsia between participants in the PPV group and the scleral buckling (SB) group (RR = 1.04, 95% CI: 0.82 to 1.33). There was little or no difference in metamorphopsia between gas and silicon oil (SO) in the PPV group (RR = 0.89, 95% CI: 0.69 to 1.13).
UNASSIGNED: The incidence of postoperative metamorphopsia is higher in macular-off RRD, and PFCL should be a preferred choice to prevent postoperative
metamorphopsia in macula-off RRD cases.
