Abstract:
〈 b 〉 〈 i 〉 Purpose: 〈 /i 〉 〈 /b 〉 To evaluate the visual prognostic factors in patients with pseudophakic epiretinal membrane (ERM) after vitrectomy using spectral domain optical coherence tomography (SD-OCT). 〈 b 〉 〈 i 〉 Method: 〈 /i 〉 〈 /b 〉 A retrospective review of patients with pseudophakic ERM having undergone vitrectomy was conducted. Best corrected visual acuity (BCVA) and SD-OCT were conducted before and 1, 3, and 6 months after vitrectomy. Known visual prognostic factors, such as inner-retina irregularity index, central foveal thickness (CFT), central inner retinal layer thickness (CIRLT), cone outer segment tip defect length, and photoreceptor outer segment length, were reviewed and their correlation with BCVA was analyzed. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Forty-three patients (mean age: 64.88 ± 10.46 years) with pseudophakic ERM were included. BCVA significantly improved after vitrectomy (logMAR 0.30 ± 0.24 vs. 0.11 ± 0.14, 〈 i 〉 p 〈 /i 〉 & #x3c; 0.001). The preoperative high inner-retina irregularity index significantly correlated with poor postoperative BCVA in patients with pseudophakic ERM (correlation coefficient 0.583, 〈 i 〉 p 〈 /i 〉 & #x3c; 0.001). Postoperative improvements of inner retinal SD-OCT findings, such as inner-retina irregularity index, CFT, and CIRLT, were significantly associated with the amount of BCVA improvement after ERM surgery (correlation coefficients were as follows: inner-retina irregularity index – 0.711, 〈 i 〉 p 〈 /i 〉 & #x3c; 0.001; CFT – 0.462, 〈 i 〉 p 〈 /i 〉 = 0.002; CIRLT – 0.596, 〈 i 〉 p 〈 /i 〉 & #x3c; 0.001). However, preoperative outer retinal SD-OCT findings were not associated with postoperative visual prognosis. 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 From this study, we determined the visual prognostic factors of ERM surgery without confounding factors, such as visual acuity improvement following combined cataract surgery, and inner retinal SD-OCT findings more significantly associated with the visual prognosis of ERM surgery compared to outer retinal SD-OCT findings.
