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) in different time points during one year follow up.

Setting/Venue

OCT can detect retinal thickness changes in RRD. These changes can be modified in the follow up time. RRD by itself or secondary to the surgical procedure could modify macular thickness

Methods

We performed a single-center cross-sectional descriptive study including 49 eyes of patients with macula OFF RRD after VPP; the contralateral eye was used as the control group. All participants underwent an ophthalmic examination that included refraction, axial length (AL), and OCT using Spectralis spectral-domain (SD)-OCT.

Results

Thirty-six of the patients were male and 16 female and 40.8% of the eyes were right one. Central foveal thickness was diminished in in 1 month and 3 months’ time points. There were not differences in the 6- and 12-months examination. The parafoveal circle was similar in both groups but there were statistically differences in the inferior and nasal outer ring of the ETDRS grid, in the 1 month follow up. After one year, differences were only found in the outer temporal and nasal rings.

Conlusions

The findings of this study suggest that retinal thickness remains comparable 1 year after RRD was successfully treated. These may indicate that there is a progressive anatomical restoration in the macular area.
