Risk of newly developing visual field defect and neurodegeneration after pars plana vitrectomy for idiopathic epiretinal membrane.

摘要: Background/Aims Pars plana vitrectomy (PPV) is widely performed in patients with idiopathic epiretinal membrane (iERM) to improve vision. Postoperative visual field defects (VFDs) have been previously reported. However, whether they occur when using the most recent PPV system, and frequency of VFDs as measured by standard automated perimetry, remain poorly documented were examined this study. Methods Data 30 eyes (30 patients; mean age, 66.1 years; 15 men) who underwent for iERM during February 2016–June 2019 had preoperative postoperative measurements perimetry (Humphrey analyser 30-2 program) retrospectively analysed. Eyes diseases other than iERM, including moderate-to-severe cataract or excluded. Results VFD, defined Anderson Patella’s criteria, was found 73.3% 1 month after PPV. After age adjustment, internal limiting (ILM) peeling identified a risk factor VFD (p=0.035; 95% CI 1.173 92.8). frequently observed nasally (86.4%, p=0.002), on optical coherence tomography measurements, ganglion cell layer (GCL) thinning temporal fovea (p=0.008). Thinning superior inferior retinal nerve fibre layers GCL significant ILM (all p Conclusion may cause inner degeneration lead development PPV, which should be further examined.
