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.
