Purpose: To study retinal thickness using optical coherence tomography (OCT) (Spectralis OCT) in patients after undergone pars plana vitrectomy to repair rhegmatogenous retinal detachment (RRD) during different time points over 1 year follow up. OCT can detect retinal thickness changes in RRD. These changes can modify in the follow up time. RRD by itself or due to the surgical procedure could induces macular thickness changes.
Methods: We performed a single‐center cross‐sectional descriptive study including 49 eyes of patients with macula OFF RRD after 23 PPV + SF6 as tamponade; the contralateral eye was used as the control group. All participants underwent a complete ophthalmic examination that included refraction, axial length (AL), and Spectralis spectral‐domain (SD)‐OCT.
Results: Thirty‐six of the patients were male and 16 female; 40.8% of the eyes were right one. Central foveal thickness was diminished in 1 month and 3 months time points. There were not differences in the 6‐ and 12‐months examination. The parafoveal ring was similar in both groups but there were statistically significant differences in the inferior and nasal outer ring of the ETDRS grid, in the 1 month follow up. After 1 year, differences were only found in the outer temporal and nasal rings.
Conclusions: The findings of this study suggest that retinal thickness remains similar 1 year after RRD was successfully treated. These may indicate that there is a progressive anatomical restoration in the macular area.
