Abstract
PURPOSE: To investigate retinal thickness in the central and parafoveal subfields, including segmented analysis of the inner and outer retinal layers, after vitrectomy for macula-off rhegmatogenous retinal detachment (RRD) repair. METHODS: Twenty-four eyes of 24 patients who underwent primary vitrectomy for macula-off RRD repair were enrolled in this study. Spectral-domain optical coherence tomography examination and best-corrected visual acuity (BCVA) measurements were performed at 1, 3, and 6 months after vitrectomy. RESULTS: At 1, 3, and 6 months after vitrectomy, retinal thickness in the temporal parafoveal subfield was more significantly (P = 0.004, 0.001, and 0.003, respectively) correlated with BCVA than the central subfield (P = 0.014, 0.001, and 0.022, respectively). Segmented analysis showed significant correlations between the retinal thickness of both the outer layer (P = 0.018, 0.030, and 0.018, respectively) and the inner layer (P = 0.003, 0.002, and 0.001, respectively) in the temporal parafoveal subfield and BCVA at every time point after vitrectomy. CONCLUSIONS: These results suggest that retinal thickness in the temporal parafoveal subfield may most closely reflect postoperative BCVA after macula-off RRD repair.
