Abstract:
Objective To observe the retinal microstructure changes in patients with rhegmatogenous retinal detachment following vitrectomy procedures and its correlation with the best corrected visual acuity (BCVA).Methods Patients who were diagnosed with rhegmatogenous retinal detachment and underwent vitrectomy were recruited in this study.BCVA and optical coherence tomography (OCT) examination were performed at 1 week,1 month,3 months and 6 months after operation for recording the neurosensory retinal thickness and outer nuclear layer thickness as well as observing the occurrence of ellipsoid zone,external limiting membrane rupture,macuiar edema,macular epiretinal membrane.Results A total of 32 eyes from 31 patients were followed up,and the BCVA became better as the follow-up prolonged.Both neurosensory retinal thickness and outer nuclear layer thickness thickened from 1 week [(122.75 ± 111.84) μm and (79.06 ±76.67) μm] to 3 months [(163.28 ± 133.10) μm and (108.66 ± 120.40)μm],and slightly thinned at 6 months [(159.50 ± 99.26) μm and (99.22 ± 74.89) μm].AS follow-up went by,the occurrence rate of ellipsoid zone and external limiting membrane rupture were 68.8％ and 53.1％,65.6％ and 46.9％,56.3％ and 40.6％,50.0％ and 37.5％ at 1 week,1 month,3 months,6 months,respectively,and both variables were significantly correlation with the patients' BCVA.Conclusion The neurosensory retinal thickness and outer nuclear layer thickness in patients with rhegmatogenous retinal detachment became gradually thicker and the vision became better during follow-up.Meanwhile,the ellipsoid zone and external limiting membrane rupture are the key factors for patients' BCVA.
